Patch notes

The Atrium, and a few things put right.

• New: The Atrium. A thirteen-speaker layout built for how Atrium's engine works: centre, a front pair, front wides, sides, rears, and two pairs overhead. Every speaker carries something the others do not, so it adds direction and envelopment without stacking copies of the same sound. Pick it from the arrangements in Sources.
• Sources are colored by where they sit. Gold is the centre, orange the front, green the sides, violet the rears, blue anything overhead, in the room, the height strip and the list, with a key under the arrangements. Drag a speaker behind you and it changes color.
• Fixed: head tracking could carry on after you switched it off. It happened when the switch went off within a couple of seconds of the headphones connecting. Turning it off now recentres the sound straight away and stays off.
• Fixed: the room's reverb could stay turned after tracking stopped. Returning to forward now always re-synthesises it.
• The soundstage switch reads "Visualize sound".

A new look, and rooms that behave like rooms.

• Atrium has a new interface. Rebuilt from the ground up in the same language as the website: a calmer layout, larger type, one clear action per screen, and the same four themes. Everything is where it was, it just reads better.
• Head tracking (beta). With supported Sony headphones connected, turn your head and the sound stays where it is in the room. The switch on Spatial Audio only unlocks when a supported pair is connected, and it lists which ones. Windows keeps taking the head tracker for a driver that cannot use it, so the card can repair that once or every time, each with one administrator approval.
• Spatial audio is rendered through measured ears. Every speaker, every reflection and the room's tail now pass through a measured head and ear response instead of a formula, with your spatial test results shaping it. Sources sit outside the head and stay put.
• Every speaker in an arrangement now bounces off the room. A 7.1, Atmos or In The Round room used to reflect only its front and side speakers, at a single bounce. Now every speaker reflects, rears and heights included, with second bounces, so a full room sounds like the same room with one speaker soloed, only fuller.
• Bass hits like the original. A kick through the stereo arrangement was arriving 4.7 dB lighter than the same kick with Atrium bypassed, with its shape intact. The cause was level accounting in the mixer, not the room, and it is fixed. The room's low end is also warmer, since the late tail was losing most of its bass.
• New: Screening Room. A treated home theatre with almost no bounce, so dialogue stays clear and close when you watch something.
• New: Visualise sound. A switch on the soundstage that draws the real traced paths sound takes from each speaker, off the walls, to you. Light leaves the speakers on each bass hit, and the speakers flash with it. It runs on the graphics card and is off by default.
• Fixed: soloing one speaker still let the rest be heard. In a stereo arrangement the centre of the mix kept playing from the other side. Solo now leaves exactly the soloed speaker sounding.
• Fixed: In The Round leaned into the left ear. The layout put every direct channel on the left half of the circle. It is now mirrored pairs.
• Fixed: the room picture drew the same paths for every arrangement until you soloed something. It was drawing the room's own single source rather than the speakers.
• Removed: the Spatial audio switch on Playback. Spatial rendering is on whenever a room is applied, so the switch only duplicated the room choice.

Your headphones are recognized when you connect them.

• Atrium follows whatever you are listening on. Connect a pair of headphones and Atrium selects them, along with the correction made for that model. Switch to your speakers and it steps back to a neutral setting, because a correction shaped for headphones is wrong over speakers. Switch back and your headphones return. Windows cannot tell Atrium what is plugged into a headphone socket or hanging off a USB adapter, so for those it asks you once and then remembers.
• One Signature, across every headphone you own. Your hearing tests, your EQ and your spatial settings used to belong to whichever headphone was selected, so changing headphones swapped them out and a new pair started from nothing. Your ears do not change when you change headphones, so now none of it does. Each pair still gets its own correction, because that part is about the headphone rather than about you.
• Hearing assist turns itself on when your hearing test shows you need it. Atrium already measured this and then waited to be asked. If your test found a real loss, the help is applied from the start. You can still switch it off, and if you do it stays off.
• Fixed: the volume slider could stay at zero after switching devices. Coming back from a muted device to one that was playing normally, the slider could stay down and stay muted. Atrium mistook the new device for an echo of its own volume change.
• Fixed: the level meter could freeze instead of settling. When audio was rebuilt after a device change the meter kept its last reading, which made it look like sound was still flowing when it was not.

Hotfix: a short sound from any app could silence everything.

• Fixed: a brief sound from one app could cut off all your audio. A launcher opening, a notification chime, a message arriving: anything that made a short noise could stop every other app being played through Atrium. The cause was in how Atrium combines several apps into one stream. It lines them up sample by sample so they stay in step, and it waits for the slowest one, but an app that had only just been picked up counted as something to wait for before it had produced any sound at all. When the sound was already over by the time Atrium noticed the app, there was nothing to wait for and everything stayed silent. Atrium now waits only on apps that have actually delivered audio.
• Atrium now records this kind of fault instead of leaving you to notice it. The problem produced total silence and wrote nothing to the diagnostic log, which made it hard to tell from nothing playing. The log now reports when the mix stalls, names the app holding it up, and says when it clears.

Atrium asks your age range, and starts counting two anonymous things.

• New: an optional age range during setup. Hearing changes with age in well-documented ways, so knowing roughly how old you are lets Atrium read your hearing test more accurately, especially at the high frequencies where the test is least certain. It does not change your sound on its own: if you never take the hearing assessment, giving your age changes nothing about what you hear. "Prefer not to say" sits alongside every option and costs you nothing.
• Atrium now sends two anonymous counts once a day: your age range, if you gave one, and which headphone model you have selected. This is how we learn who Atrium is actually for and which headphones to prioritise, which is otherwise close to impossible because most people use Atrium free and never make an account. It is a counter, not a log: one row per install per day, keyed by a one-way hash that is thrown away after two days. No IP address is stored, and nothing links it to you, to an account, or to yesterday. Your hearing results, your settings and what you listen to are not included and never leave your device.
• The privacy policy has been rewritten to say all of this plainly, including that the Sound Tolerance test's answers stay on your device and are never part of those counts. Two older errors are fixed with it: the policy said an account was required (it has been optional since 2.0.3) and described the update check as hashing your browser agent, which it does not.
• Existing setups are unaffected. If you already finished setup you are never asked your age, your tuning is exactly as it was, and your age range simply reads as not given.

A new hearing test for sounds that are uncomfortable, not just sounds you cannot hear.

• New: the Sound Tolerance test. Every other test in Atrium finds sound you struggle to hear, so it can be lifted. This one finds the opposite: frequencies that are uncomfortable, harsh or painful to listen to. Atrium then keeps those frequencies lower, caps how loud they are allowed to get, and will not boost them again for any other reason, including your hearing results, your headphone correction or your sound preference. It takes about four minutes, it is free for everyone, and it is in Personalization.
• The test never gets louder without you asking. Each sound starts at a set level and only comes down. Stop at the first thing you would not want to listen to. You can leave at any point with the Escape key, and whatever you marked before leaving is still used.
• If you use tinnitus relief, Atrium now suggests this test. Reduced tolerance to everyday sound is common alongside tinnitus, so it is worth measuring.
• Fixed: taking a hearing test could leave you with no audio until you restarted Atrium. Any assessment, not just the new one. When a test finished, Atrium did not always hand playback back to your apps, and there was nothing on screen to say so. This affected every version since 2.0.0.
• Atrium now leaves games alone. Games play untouched, with no Atrium processing at all. Game engines manage their own audio and often fight anything that tries to adjust it, which came out as crackle, dropouts and stutter that spread to everything else playing. Stepping aside is the honest fix while that is true. Everything else you play keeps its full tuning.
• The Gaming sound profile has been removed. With games no longer processed, a profile that tuned them promised something it could not deliver. If you were using it, Atrium switches you to Music and your hearing profile is unchanged. Music and Browser are unaffected.
• Your personalization percentage has changed, and nothing was lost. The score now covers six tests instead of five, so a profile that read 100% before will read 85% until you take the new one. Your existing results and your tuning are exactly as they were.

Fixed: the Apple TV app went silent while Atrium was running.

• Fixed: Apple TV, and other apps that play protected video, went completely silent while Atrium was running. Apple TV does not play its own audio on Windows. It hands playback to a separate protected system process, which Atrium saw as an ordinary app and turned down so it could capture it. Windows then refused to hand over that audio, so there was nothing to play back in its place: the app stayed silent for as long as Atrium was open, and it never recovered on its own. Atrium now notices when an app's audio never arrives, hands the volume back within ten seconds, and lets the app play normally. It keeps watching, so an app that was only paused goes straight back to being processed the moment it plays again.
• Apple TV plays at normal volume, without Atrium processing. Protected video is sealed off by Windows itself, so no equaliser, spatial audio or hearing assistance can reach it. Everything else you play keeps its full tuning.

Game audio fixed.

• Fixed: choppy, crackly audio while playing games. Some games (Cyberpunk 2077 and Assassin's Creed Shadows among them) continuously set their own Windows volume, the same control Atrium used to keep an app quiet while capturing it. The two fought over one knob several times a second, and every round of that fight was audible: dropouts, crackle, and stutter that spread to everything else playing. Atrium now keeps apps quiet with a different Windows control that multiplies with the app's own volume instead of competing with it, so the fight cannot happen at all. A side benefit: the Windows volume mixer no longer shows apps at 0% while Atrium runs, and a per-app level you set there keeps working.
• Fixed: games could come out far too quiet. Windows remembers the quiet level older Atrium versions set on an app, and re-applied it when the app next made sound, stacking with the new mechanism. Atrium now repairs that leftover the moment it appears instead of only at launch.
• Atrium now steps aside for audio it cannot capture cleanly. A few games route some audio in a way that bypasses per-app volume entirely. Fighting that is always audible, so after 15 seconds of it Atrium stops processing that app for the session and lets it play exactly as if Atrium were not running. Everything else keeps its tuning. The diagnostic log records when this happens.
• Fixed: skips under heavy load. When a game saturated the processor, Atrium's audio threads could fall behind and then throw away up to a second of sound in a burst of small skips. Its audio threads now run at the same scheduling priority games use for theirs, and when a genuine overload does happen, Atrium drops once and moves on instead of skipping repeatedly.

Hotfix: audio no longer dies and stays dead.

• Fixed: audio could stop and Atrium would show no audio stream until you restarted it. When Atrium rebuilt its audio path after the computer woke from sleep or the output device changed, the rebuild could hit the one moment the device was not ready. The failure then went two ways, both bad: Atrium either fell back to listening to the microphone instead of your apps, or ended up claiming to run with no capture at all. Either way it looked healthy to its own recovery logic, so it never tried again. Atrium now stays silent on a failed rebuild, retries every second until the device is back, and never falls back to the microphone.
• The diagnostic log now survives restarts. It used to be wiped at the start of every capture run, which meant a recovery erased the evidence of the fault that caused it. It now keeps history across runs, with a size cap.

Security hardening. Nothing changes in how Atrium sounds.

• Atrium's interface now runs under a strict content policy. The app window is locked down so it can only load code and styles that ship inside Atrium itself, and can only talk to Atrium's own servers. Nothing about this is visible in normal use; it exists so that a bug in the interface cannot be turned into a way to reach your account.
• Signature Edition now depends on your account alone. A local setting could previously switch on the paid features. It was there for development, it was readable by anyone who looked, and it is gone.
• Behind the scenes: the account page escapes everything it displays by default, the website sends stricter security headers, and Atrium now counts how many people are using it in a way that stores no IP address and cannot be traced back to a machine from one day to the next.

Atrium leaves your volume alone, and stops giving up on itself.

• Fixed: opening Atrium changed your system volume. Atrium was setting your output device to 100% every time it started audio and quietly making up the difference inside itself. That step belongs to the old virtual-cable setup, where the sound passed two volume controls. There is only one now, so Atrium matches the level you already had instead of overwriting it.
• Fixed: a short sound from another app could stop Atrium completely. The guard that watches for runaway feedback measured the time between two loud moments rather than a continuous run of them. An app that plays a brief click, such as a launcher confirming it opened, could arm the guard on one click and trip it on the next one seconds later. Atrium now measures an unbroken run, and recovers by itself if the guard ever does trip.
• Fixed: Atrium could stop working after a long spell with nothing playing. Nothing was watching whether playback was still alive unless audio was flowing, so a stream that ended during a quiet period went unnoticed until you pressed play. Atrium now checks continuously and rebuilds the audio path on its own.
• An account is now optional. The free version runs entirely on your PC with nothing stored on a server. An account is free and adds what needs one: carrying your Signature to another computer, the phone app when it arrives, and the shared song library. Signature Edition still requires an account. Signing out no longer erases anything on your PC.

Switching audio devices now works.

• Fixed: changing your output device did nothing. Atrium kept playing to whichever device an older version had pinned, so plugging in headphones or switching in Windows appeared to be ignored. Atrium now follows your system's output device and moves with it, on launch and whenever you change it.
• Fixed: an app could be left silent on a device you switched away from. App volumes are stored per device by Windows, and Atrium was only putting them back on the device it was using at the time. It now restores every device, and repairs any that were left quiet by an earlier version.
• Fixed: the volume slider did not match your device. Atrium's slider now moves the volume of the device it is playing to, and follows the Windows slider and your volume keys, so there is one number instead of two.

Fixes audio that sounded robotic or warbly.

• Fixed: audio could sound robotic and warbly. Atrium could start capturing twice at launch, so every app was picked up two times and the two copies played over each other a few milliseconds apart. Only one capture can now exist at a time, whatever starts it.
• Fixed: audio could stay silent after the laptop woke from sleep. Atrium now notices when playback has stopped draining and rebuilds the audio path by itself.
• Capture now always runs at the exact rate playback uses, so a device that changes format while the machine sleeps can no longer knock the two out of step.

No more virtual audio cable.

• Atrium now captures each app directly. There is nothing to install, nothing to route, and no "set your output device to CABLE Input" step. Install Atrium and it works. Your Windows sound settings are never changed.
• Setup is gone from onboarding, because there is nothing left to set up. The audio-device pickers are gone from Settings for the same reason.
• Launch at startup was fixed. It no longer opens a terminal window, it starts to the tray instead of opening the full window, and a login entry left behind by an older install is repaired automatically.
• Requires Windows 11. Windows 10 stays on 1.3.4, which keeps working and is still available on the site.

Volume fix.

• Fixed: Atrium could start far too loud, and the volume slider felt useless at low levels. Two bugs from the recent one-knob volume change. On launch the engine ignored your saved volume and ran at full, and restarting audio routing could briefly slam the volume to maximum. Both are fixed: your saved level is applied on launch, and the slider now scales the sound the way it should, all the way down.

The phone remote connects over any network.

• Fixed: the phone remote could not reach a PC connected by Ethernet. The PC now offers the phone every address it has, and the phone uses whichever one it can reach, so the remote works on Ethernet, WiFi, or both at once. If your PC switches networks mid-session the phone reconnects on its own. Re-pair once (Settings, Phone remote) to pick this up.

Hotfix for 1.3.1.

• Fixed: the minimize button did nothing. Hiding to the tray was blocked by a missing window permission, and the failure was silent. It is granted now, and if hiding ever fails again the button falls back to a normal minimize instead of doing nothing.
• Fixed: the level meters went quiet at low volume. The 1.3.1 volume fix moved attenuation into Atrium's own volume, and the meters were measuring after it. They now show the music, not the volume setting.

The basics behave.

• Close means quit. The X (and Alt+F4) now exits Atrium fully, and your real output device is restored as the system default on the way out. Quitting no longer hides to the tray.
• Minimize means tray. The minimize button hides Atrium to the tray with audio still running. The tray icon, or just launching Atrium again, brings it back.
• Only one Atrium at a time. Launching a second copy focuses the one already running instead of starting another engine.
• One volume control, not two. Choosing an output device now sets that device's system volume to 100% and folds what it was absorbing into Atrium's own volume, so loudness does not jump and the volume keys are the single control. Before this, the device's Windows volume silently stacked with everything else.
• Closing the mini player still just hides the mini player.

The hearing assessment goes deeper, and hearing assist is free.

• Hearing assist is now free for everyone. Hearing help is why Atrium exists, so it is no longer part of the paid tier.
• The assessment unlocks a deeper measurement when it matters. Everyone takes the same short assessment. If your responses suggest meaningful hearing loss, the same run seamlessly measures further: more frequencies (down to 125 Hz, up to 12 kHz), a brief full-volume reference (your volume is restored right after), and a few loudness ratings. Listeners with typical hearing never see any of it.
• Hearing assist fits itself from the deeper measurement. With the extra data it prescribes gain the way a real hearing fitting does, at up to twice the previous strength, with a ceiling set from your own loudness comfort so nothing ever gets painful. These are estimates, not a clinical hearing test.
• Works on Mac too. The full-volume reference step now runs on macOS as well as Windows.

Atrium listens to the song, not just your ears.

• Per-song EQ (Signature Edition). Atrium measures the frequency balance of whatever is playing, 31 bands at a time, and fits a gentle correction to each recording on top of your Signature. A first listen is never changed: it learns the song by hearing it through once, then applies the fitted curve from the start of the next play. Records that are meant to be warm or bright stay that way; it only steps in when a master is genuinely out of line. Turn it on in Playback.
• The 9-band graphic EQ returns. Nine sliders on the standard centres (60 Hz to 16 kHz), each controlling a band at exactly that frequency, like a car stereo or hi-fi. Free for everyone.
• New Playback tab. Everything that applies to all your listening in one place: bass enhancement, balance, volume boost, dialogue boost, hearing assist, loudness compensation, linear-phase EQ, and per-song EQ.
• Personalize is now Your Signature. Hearing assessments and the tuning built from them, under the name the app already uses for your sound.
• They are assessments, not tests. There are no wrong answers, so the app and the website no longer call them tests.
• A rebuilt first run. Audio setup first, then your data choices, then an optional hearing assessment, then straight to the app. A short tour then points out what each tab does; replay it any time from Settings.
• Contribute measurements (optional, off by default). Share the tonal profile of what you play, never audio, so Atrium learns how records are mastered. A song is only ever shared back as an average across at least three listeners. See Settings, Privacy.
• Faster EQ response. Parametric edits now apply while you drag instead of after you stop.
• Fixed: the spectrum visualiser froze and lagged. It now tracks the music smoothly without loading the audio engine.
• Settings is back in the top right, and the account menu now opens your account page and the about page on the website.

Your phone becomes a remote.

• Phone remote. Turn it on in Settings, Devices, and pair the new Atrium mobile app by scanning a code. Play, pause, skip, volume, EQ presets, environments and spatial arrangements, all from your phone on the same WiFi. The phone also shows your Signature curve anywhere.
• Refreshed home page. One Environments row with the four base rooms, and recent EQ presets in one place.
• Current setup in the sidebar. Your EQ profile, environment, and spatial arrangement at a glance, each one click from its page.
• One Environments page. Presets, your custom rooms, and the create button together, no tabs.
• Atrium speaks to you. Your Signature, Apply your Signature, Your presets.
• Theme polish. The silver and gold button gradients read clearly in every theme.

A simpler equalizer, custom presets, and a batch of real fixes.

• Simpler graphic EQ. Six broad bands with plain names: Sub, Bass, Mid, Treble. It is a coarse view of the same EQ the parametric view edits: moving a slider adjusts the matching parametric bands, your Signature shows up on the sliders, and Reset returns everything to flat.
• Custom EQ presets (Signature Edition). Save the current EQ under a name and it appears in a Your presets section. Selecting your preset and saving again updates it in place.
• Fixed: sound stayed muted after a hearing assessment. Music now resumes on its own the moment a test closes, on Windows and Mac.
• Fixed: In The Round favored the left ear. The back source now carries balanced content.
• Fixed (Mac): play/pause did nothing. The buttons now control Spotify and Apple Music; macOS asks for permission once.
• Every assessment has Back and Exit. Back returns one step (previous frequency, or the test intro); the X leaves the test at any time. Assessment results apply on their own when a test finishes.
• Input locked to the virtual cable. A microphone can never become Atrium's input, and the setup wizard rescans your devices every time it opens.
• Refreshed home page and sidebar. One Environments row on Home, a Current setup card in the sidebar showing your EQ, room, and spatial arrangement, and recent EQ presets in one place.
• New defaults. Fresh installs start in the Terracotta Light theme with the Music profile. Existing choices are kept.
• Sign in with Google on the website, for both the site and the app's device sign-in.

Atrium is now on Mac, plus audio and interface fixes.

• Atrium for Mac. A signed and notarized Mac build, using the free BlackHole virtual driver. Opens with a normal double-click.
• Audio picks your output automatically. On a fresh launch, Atrium now selects a working output device on its own instead of you having to pick one each time. It never routes into the capture cable by mistake.
• Fixed: the thin light line at the bottom of the window.
• Cleaner top bar. The settings gear moved into the profile menu, and your avatar now shows your account initials.
• The mini player tidies up. Opening it now sends the main window to the tray, and closing it brings the window back.
• Faster sign-out of removed devices. A revoked session now signs out within an hour instead of at the next restart.
• macOS audio reliability: correct device enumeration on recent macOS, unique device labels, and automatic sample-rate matching. On Mac the bottom-bar player also controls Spotify and Apple Music, and standard shortcuts (Cmd+R, copy, paste, quit) work.

Atrium now uses accounts.

• Sign in to use Atrium. Create a free account in seconds; your browser opens, you approve the PC, and you're in. Your subscription and settings follow the account to any PC.
• Settings live on your account. Theme, hearing assessments, profiles, rooms and EQ sync while you use the app. Signing out resets this PC to defaults; signing back in restores everything. Audio device routing stays on the PC.
• Manage everything in one place. Settings → Account → Manage account opens your account page: subscription, password, connected devices, and account deletion.
• New price: $4.99 a month or $49.99 a year. Existing subscriptions keep their current price.
• A shorter first-run setup. One hearing assessment, about 5 minutes. The other tests moved to Personalize.
• Free and Signature tiers adjusted. Free: 9-band graphic EQ, generic headphone profile, the hearing assessment, bass enhancement, balance and volume boost. Signature adds the parametric EQ, the 4,300+ headphone database, the remaining assessments, spatial audio and every enhancement.
• Settings cleanup: output device and UI sounds moved to Audio Devices; several info panels removed.

A shorter spatial assessment, plainer wording, and a spatial audio fix.

• Fixed: sources drifting out to the walls. Applying a room repeatedly pushed your 3D sources further out each time until they piled up against the walls and the arrangement lost its shape. Saved arrangements now keep their intended positions. If an arrangement was already affected, re-pick the arrangement and save it to the room again to reset it.
• The spatial assessment is shorter. The front/back and movement sections now stop as soon as your accuracy is clear, so a confident listener answers fewer questions. Accuracy of the result is unchanged.
• Plainer wording throughout the app. Descriptions now say what each control does, without the marketing language.
• Fixed: the welcome screen showed the old product name.
• The audio setup guide now shows only the Windows instructions.

Smarter tuning, faster tests.

• The hearing assessments are faster and sharper. All four now adapt to your answers as you go · the threshold assessment builds a continuous audiogram, and the loudness, masking, and spatial assessments stop the moment they're confident. Less time, more accurate.
• New Parametric EQ. Switch the Equalizer to a precise multi-band editor · up to 20 bands with adjustable frequency, gain, and Q. It seeds from your Signature, so every tweak refines your personalization instead of starting from flat.
• 4,000+ headphone presets. Search a large AutoEq-based database and apply a neutral correction curve for your exact model.
• One-tap Signature on the Equalizer. Apply your full personalized tuning to the EQ page with a single button.

More in the free tier, and simpler spaces.

• Sound Preferences and L/R Ear Balance are now free. Tune your taste and correct the natural difference between your ears without Signature Edition.
• A focused set of acoustic spaces · Recording Studio, Concert Hall, Bedroom, and Outdoor Space, each carefully modelled. (Custom rooms stay in Signature.)
• A bypass toggle is back on Home. Flip Atrium's processing off for an instant raw-audio A/B from the Live audio card · the Ctrl+Shift+A hotkey still works too.

• Fixed: opening the mini player from the bottom-bar button could crash Atrium. (Opening it from the tray menu always worked.)

Much lighter on the Spatial Audio tab.

• The 3D soundstage and object mixer were redrawing far more than they needed to, driving CPU and GPU use up whenever that tab was open. They now update efficiently · same look, a fraction of the cost.

Lighter and tidier.

• Lower CPU while you listen. The spectrum analyzer now uses a far cheaper method, and Atrium no longer wastes effort drawing meters when it's tucked away in the tray.
• Windows remember where you put them. The main window's size and position · and the mini player's spot · now persist across launches.
• A handful of empty-state and label fixes so nothing reads as broken on the light themes.
• The compare/bypass buttons are gone from the interface (the Ctrl+Shift+A hotkey still does it).

A more finished Atrium, and Signature Edition.

• A custom titlebar in Atrium's own colors replaces the plain Windows bar · themed to match, with the Oculus mark and clean window controls.
• A launch screen with the Atrium medallion while everything spins up, instead of the interface popping in.
• Global hotkeys: Ctrl+Shift+A toggles A/B compare and Ctrl+Shift+M mutes · even inside games and fullscreen video, with a soft confirmation cue.
• Scroll over the volume in the bottom bar to adjust it; middle-click the tray icon to pause or resume.
• Atrium Pro is now Signature Edition · the full personalized sound system. (Pricing: $9.99/mo · $99.99/yr.)
• The Home page's "For you" row now surfaces your recent rooms for one-click recall.
• The equalizer's presets are reorganized into tidy Moods and Activities groups.
• A quiet "what's new" note after each update, and the update prompt now finds you even on long tray sessions.

Your volume keys work again.

• Keyboard volume keys now control Atrium. While Atrium is enhancing your system audio, the volume and mute keys (and the Windows volume display) adjust what you actually hear · in sync with Atrium's own volume slider.
• Listening Insights now records across the whole app, with its on/off switch live in Settings → Privacy.

Simpler settings, smarter foundations.

• A new General tab (the first thing you see) gathers your output device, theme, UI sounds, launch-at-startup · and a Check for updates button that downloads and installs in place.
• The Spatial Realism, Performance, and Updates tabs are gone; their useful parts moved where they belong.
• Atrium can now remember your tuning choices and what was playing when you made them · the foundation for sound that adapts to you. Stored only on this device, never uploaded, with an on/off switch in Settings → Privacy.
• Your personalized profile is now called My Signature.
• Theme refinements: Platinum's light mode gets a soft blue backdrop, and visualizer grids, sliders, and edge highlights now render correctly in both light themes.

A mini player, two new themes, and a smarter bottom bar.

• A compact always-on-top strip · album art, track, play/skip controls, volume, instant A/B, and profile switching · for when the full window is more than you need. Open it from the bottom bar or the tray menu, drag it anywhere.
• Terracotta Light · the warm terracotta gold on bright cream.
• Platinum Dark · silver and ocean blue on dark slate.
• Platinum themes are part of Atrium Pro.
• The bottom bar got a redesign: media controls now sit dead-center and stay put, with your profile and environment grouped on the left.
• The tray's Pause/Resume label now always reflects the engine's real state.
• Atrium now always prefers the virtual audio cable as its input · fresh installs no longer accidentally capture the microphone.

Atrium becomes part of your system.

• Closing the window no longer quits Atrium · it keeps enhancing your audio from the system tray. Left-click the tray icon to reopen; quit from the tray menu.
• The tray menu can also pause/resume audio and switch app profiles without opening the window.
• New Launch at startup toggle (Settings → General) · Atrium starts quietly in the tray when you sign in, so your sound is always tuned.
• The bottom bar now shows the current track with album art, with play/pause and previous/next controls that drive the actual media app (Spotify, your browser, anything with media controls).
• Startup no longer sounds muffled. Atrium now fully restores your active room, its saved arrangement, and the spatial upmixer settings on launch · previously they only applied after re-clicking the room.

• Hearing assessments that map your ears in about ten minutes · threshold, loudness sensitivity, sound separation, spatial hearing, and L/R balance. They use soft, gently *pulsing* tones (not steady sines) so even the faintest sound is easy to identify, with a Replay button whenever you want another listen.
• Per-ear (L/R) correction · measures the difference between your ears and balances it. Almost nobody gets this right.
• A personalization score that grows as you complete more, so you always know how tuned-in Atrium is.
• A precise, personalized equalizer built from your hearing profile.
• An optional linear-phase EQ mode for transparent, phase-perfect playback.
• A modern look-ahead limiter so boosted audio never clips or crunches.
• Loudness compensation that keeps bass and treble balanced at quiet volumes.
• A personalized structural HRTF · externalization, real front/back, and a genuine sense of height, tuned to your spatial-hearing results (or by ear).
• Acoustic environments · from a dry treated studio to a live concert hall · modelled from real room dimensions, materials, and early reflections.
• A 3D spatial mixer for arranging sources around you.
• Three sound profiles · Browser, Music, and Gaming · each tuned to the content it plays, with your hearing profile shared across all of them.
• Switch in a click from the bottom bar.
• Tinnitus relief · match your tone and quietly notch it out (a relaxation aid, not a treatment).
• Hearing-comfort framing throughout.
• No accounts, no cloud, no analytics, no ads. Your hearing data and your audio never leave your computer.
• One-tap Delete all data in Settings.
