Reviewed the branch and measured every audio file on it.

Howler's fade only completes while the volume moves toward the target, so a fade from a value to itself hangs: the "fade" event never fires, whatever was scheduled on it never runs, and the interval and listener leak. SoundManager.setAmbience already guarded the zero case and the same trap was left open twice elsewhere: - AudioMixer eviction faded from volumeFor(category), which is 0 whenever the channel slider is down or the focus duck has silenced it. The stop scheduled on "fade" never ran, so the evicted cue kept playing outside its budget. - setAmbience guarded target === 0 but not from === target. Panning between two structures at a constant zoom can re-enter before a pending fade-out has stepped the volume, with the loop already sitting at the target. Both now set the volume directly when there is nothing to move.
setAmbience pushed the new gain into the mixer as its first statement.
setAmbienceEnvelope runs applyTo("ambience") synchronously, which calls
back into retargetAmbience -- and that still sees the outgoing track as
current, so it snapped the live loop's volume to the incoming envelope
before anything had faded.
AmbienceController always pairs track === null with gain 0, so every exit
from ambience range silenced the loop first. fadeOutCurrent then read
from === 0 and took its stop-immediately branch, and the 500ms fade never
ran. Leaving range is the common case, so the loop hard-cut to silence
every time; track-to-track crossfades were unaffected because their gain
is non-zero.
The envelope now lands after fadeOutCurrent has captured the level the
loop was audibly at. The outgoing howl is already in fadingOut by then,
so the change listener leaves it alone.
The old test only asserted fade had been called at all, which the earlier
fade-in already satisfied; it now checks the fade runs on the outgoing
howl, from a real level down to zero, with no synchronous stop.
Also stop leaking a Howler listener on every cue. play() and previewCue()
register once() on both "end" and "stop" for the same id, but once() only
strips the listener for the event that fires -- a cue that plays out
leaves its "stop" listener behind, and one stopped early leaves its "end"
listener. The Howls are cached per cue on a mixer that lives as long as
the page, so a cue like click grew its listener list, and _emit's linear
scan with it, for the whole session. Whichever event arrives first now
takes the sibling off.

A playtester reported roughly thirty seconds of silence before the background music started. Howler defaults every sound to its Web Audio path, which XHRs the whole file and decodes it to PCM before a single note plays. gameplay.mp3 is 4.6 MB and menu-theme.mp3 is 2.2 MB, so on a slow connection play() sat queued behind the download plus the decode of a three-and-a-half-minute stereo track. playBackgroundMusic() is called at game start, so the wait landed on every game. html5: true switches those two to a streaming HTML5 Audio element, which starts after a couple of seconds instead of after a full download. It also stops us holding tens of megabytes of decoded PCM per track. The trade-off is that HTML5 looping can leave a very small gap at the loop point where Web Audio is sample-exact. A barely perceptible seam every three and a half minutes is a much better deal than thirty seconds of silence at the start of every game. Deliberately not applied to cues or ambience. Cues need the Web Audio graph and are small enough that the download was never the problem, and ambience loops continuously enough to want sample-exact looping. The mixer keeps working either way: howler applies vol * Howler.volume() to the element for html5 sounds, so both master and per-channel volume still reach them, and fade() still runs as timed volume steps. Tests now assert which path each sound takes, in both directions -- this is exactly the sort of option a later refactor would drop or spread too far without noticing. The menu theme had no test file at all, so that is new.

Two audio-polish bugs, both silent degradation rather than anything loud. Menu music was permanently dead after leaving a lobby. startMenuMusic armed its pointerdown/keydown listeners once and the "game-starting" handler removed them for good, justified by a comment asserting that returning to the home page is always a full page load. It is not: "game-starting" fires at lobby PRESTART (Main.ts, inside lobbyHandle.prestart.then), and handleLeaveLobby restores the menu chrome in place for a leave landing between prestart and the game actually starting (OPE-255). Press anything, join a lobby, leave during that window, and the home page is live again with the theme silent for the rest of the session and no gesture able to bring it back. The arming logic is now re-runnable and re-arms on a new "menu-restored" event, dispatched from the one branch that puts the home page back without navigating. Re-arming rather than replaying is the point: the autoplay rule applies to the second start exactly as to the first. arm() removes before it adds, so repeat events cannot stack listeners or build a second Howl, and the teardown still takes both gestures off -- `once` only removes the listener that fired, so a live keydown would otherwise start the menu theme over a running game. Second, retargetAmbience only protected the outgoing track. The incoming one is taken out of fadingOut immediately before its 500ms fade-in, and Howler's volume() setter calls _stopFade internally, so any volume write during that window cancelled the ramp and jumped to the target. AmbienceController re-emits for the same track every time the zoom gain moves past its epsilon, so zooming in on a structure reliably killed the fade-in and snapped the loop to full -- the abruptness the envelope is there to avoid. The subscription comment already claimed the mixer could not stomp a fade in progress; it is now true in both directions. A fade-in is re-aimed from wherever the ramp actually reached rather than skipped, so a retarget arriving mid-fade still ends on the level the envelope is asking for instead of stalling at a stale one.

The theme was created silent, handed to the mixer, and played. Register writes the channel volume straight onto the Howl, so the first note arrived at full level with no onset at all. It now plays from silence and ramps to the channel volume over two seconds, with the mixer taking the Howl on when the ramp lands. Applied to every start, not just the first: coming back to the home page from a lobby is the same moment on a page that is already open, and music slamming in there is exactly as abrupt. Three things this has to stay clear of, two of them already fixed once on this branch: - A fade whose start equals its end never completes in Howler, so on a silent music channel the settle scheduled on "fade" would never run and the theme would stay unregistered for the rest of the session. A zero target skips the ramp and registers directly -- nothing to hear, and nothing to move. - Registering during the ramp would kill it, since volume() calls _stopFade internally. Hence registering after, not before. - The pending settle is dropped when a game starts mid-ramp. Left alone, the fade-OUT completing would have fired it and handed a departing theme back to the mixer, which would then write volumes to an unloaded Howl and hold it alive for the session. The cost of registering late is that the theme does not follow the music slider for those two seconds, so a change on the channel settles it early: moving a slider is deliberate and should take effect at once. Muting is the case that makes this non-optional -- deferring it would leave the music audible for two seconds after the player silenced it. The alternative, re-aiming the ramp on every change the way ambience does, re-issues a full ramp per slider tick and would lag the slider badly. Duration checked against Howler's html5 fade rather than by ear, which I have no way to use: it steps on a timer in 0.01 increments, so at the default music level of 0.89 this is about 89 steps roughly 22ms apart -- fine-grained enough not to staircase.

…uttons Replaces the two volume sliders with the full mixer surface: Master, Music, Sound Effects, Alerts & Notifications, Ambience and Interface, each a bare 0-100 slider (unit="") because the value is squared into perceptual gain before it reaches the audio — a percentage would be a lie and dB would be worse. Mute-on-blur and a dependent "keep alerts audible when unfocused" sit below, both defaulting on, the second indented and disabled while the first is off. `disabled` is new on setting-toggle and defaults to false, so no other tab changes. Effects, Alerts, Ambience and Interface each get a Test button — Master is tested by every other button and Music is already playing. A button calls audioMixer()?.previewCue(category), stays disabled until its own cue resolves, and shows the audio_test_muted hint when the category is silent or the mixer has not been constructed yet. src/client/sound/AudioMixer.ts is the contract surface only: the interface, and a null-until-registered accessor. The mixer itself lands on #5348 and replaces that file wholesale, at which point the four buttons light up. Until then the tab stores every value correctly and the buttons are honestly disabled. en.json gains the audio_* keys and retires background_music_volume and sound_effects_volume, which nothing else referenced. The repo's TranslationSystem sync test does not catch a missing or unused user_setting key, so the tab's test file asserts the copy exists. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The owner listened to the fade-in and said it does not sound like a fade.
It does not. The mechanism was right and the curve was wrong.
Howler's fade() is linear in amplitude, and loudness is roughly linear in
dB, so a linear ramp is heavily front-loaded: it covers the bottom 30 dB
almost at once and then spends most of its length creeping through the
top few, where nothing is audible. Measured at the real defaults -- music
slider 0.5, squared by perceptualGain, times the -1 dB trim, so a target
of 0.2225, which Howler quantises into 22 steps of 0.01:
90ms 0.01 -26.9 dB 989ms 0.11 -6.1 dB
180ms 0.02 -20.9 dB 1438ms 0.16 -2.9 dB
449ms 0.05 -13.0 dB 1978ms 0.22 -0.1 dB
Within 6 dB of final at one second, 3 dB at 1.4s. The last 600ms are
inaudible and the track has perceptually arrived in about 300ms. The
first step alone is a 6 dB jump, because 0.01 quantisation is a quarter
as fine at this target as it would be at a full-scale one.
The ramp is now driven here, linearly in dB from -48 dB below target to
0, stepped every 25ms off elapsed wall-clock time. That is a flat
24 dB/second: -24 dB at the halfway mark where linear was at -6, and
still climbing 6 dB through the final 250ms. Writing the volume directly
also sidesteps the 0.01 quantisation entirely.
Stepping on elapsed time rather than a tick count matters because a
backgrounded tab throttles timers hard; the ramp then takes coarser steps
and still finishes on schedule instead of stretching out to minutes.
Everything the ramp has to keep doing, it still does: a zero target skips
it and registers directly, a music-channel change settles it early so
muting is immediate, the mixer only takes the Howl on once it lands, and
"game-starting" cancels it before the fade-out.
Completion is now ours to signal, since Howler's "fade" event no longer
fires for this. The old off("fade") guards went with it. The fade-out
still uses Howler's fade(), and fade() internally calls volume(from) ->
_stopFade(), which emits "fade" -- but only when a Howler fade interval
is actually running, which is never true of this hand-driven ramp, and
the fade-out's own handler is registered after that call. Ordering holds.
The 700ms fade-out is deliberately left linear: it is short, it happens
under a scene change, and a linear fade-out errs by dropping away late
rather than by arriving instantly, which is far less noticeable than the
same curve running the other way.
Recommended three times across this branch's reviews and never actioned. Howler's master gain now runs into a DynamicsCompressorNode before the destination, set as a limiter rather than a compressor: hard knee, 20:1 (the Web Audio maximum), 3ms attack, -3 dB threshold. Below that nothing is touched at all; above it peaks are held just under 0 dBFS. It covers the cue channels and ambience, and NOT the music. Worth stating plainly rather than letting the name imply otherwise: Howler has no createMediaElementSource anywhere in it -- the only connection into the graph is the Web Audio path -- so an html5 Howl plays straight out of its media element and past the whole graph. Both music tracks are html5 now, by design, so that they stream instead of decoding 4.6 MB and 2.2 MB up front before the first note. That gap is acceptable. The music is a mastered stereo bounce already carrying a -1 dB trim and only ever one track plays at a time. The summing risk was always the cue layer, where the per-channel budgets allow up to 16 voices at once with nothing holding the sum down. This is not a level control. No make-up gain and no reduction: the -5 dB master cut was removed on purpose and is not coming back, headroom is the -2 dB re-bounce's job, and this is only for concurrency. Installed after applyAll, because Howler builds its AudioContext lazily and the Howler.volume() write in there is what forces it into existence. Absent a context at all -- an html5-only fallback with no Web Audio -- there is no graph to splice into and this does nothing. Dispose puts the routing back, so a later mixer splices in its own rather than chaining a second limiter behind this one.

The hand-driven ramp timed itself from Howl construction. play() on a Howl that has not loaded pushes itself onto _queue and returns immediately (howler.js:800, guarded on the _state = 'loading' set at :715), so the call says nothing about when the first sample lands. These are html5 streams, so that gap is a network fetch: a few hundred ms on a warm CDN, and on a slow connection longer than the whole 2000ms ramp. When it is longer, the ramp finishes while the file is still downloading and the theme starts at full level with no fade at all -- the original complaint, reintroduced under a different cause, and only on the connections least likely to be tested. Howler's own fade() had the same deferral at the top of the function, so the old code was chained behind the play task and started when playback started. Driving the ramp here dropped that coupling; this puts it back explicitly. The ramp now starts on the Howl's "play" event. That is the right signal in every path through play(): for html5 Howler sets _playLock while the media element's play() promise is pending and clears it immediately before emitting, and the non-promise branch clears it and emits inline, so the lock is never held when the event arrives. A rejected promise emits "playerror" instead, which now settles -- no audio to ramp, but the mixer should still own the Howl rather than leak the subscription. Three details that go with it: - Teardown covers the not-yet-started ramp. While the stream is loading there is no interval to clear, only a pending "play" handler, and a departing theme that began ramping after being unregistered would write over its own fade-out. - The target is read when the ramp starts rather than when the Howl is built, since a slow load gives the player seconds to move the slider. The channel subscription still goes up immediately, so a mute during loading is honoured. - The floor is written before play() is called, and fadeIn is armed before play() for the same reason, so nothing can escape above it however the load and the writes interleave. The test double now models the deferral: play() makes no sound and begin() is playback actually starting. The previous tests passed only because they treated play() as instant.

The ramp captured its target once and subscribed to mixer.onChange purely so that muting during those two seconds took effect at once rather than when the ramp finished. That subscription could not tell a deliberate change from an incidental one, so alt-tabbing mid-ramp ducked the music channel, settled the ramp early and left the theme at full level. Since the ramp already writes the volume every 25ms it can just read the target each time instead. `t` stays the ramp's own position in dB and keeps counting on wall-clock time; only the level it scales moves. That fixes the focus case by deletion rather than by special-casing it: blur takes the target to zero, the ramp writes silence and goes on counting, and refocus resumes at the dB position it had reached. A mute still lands within one tick, which was the entire point of settling early. A slider now tracks continuously instead of ending the ramp -- better than either option considered before, and not the re-aiming that was rejected for lagging the handle, because nothing re-issues a ramp or restarts a duration. One multiply per tick. The subscription, the early-settle path, its teardown and the ordering constraints around it all go. Registration now happens in exactly one place: when the ramp completes. The zero-target guard stays at ramp start, so a channel already silent when playback begins registers at once and never starts an interval, and playerror still settles so a blocked play cannot leave the Howl unowned. That guard is the one case with no ramp to carry the level, so the mixer has to be what brings the theme up if music is turned back on. Verified rather than assumed: a new test registers a howl on a silent music channel and checks the mixer writes the new level when the slider moves. The test double no longer offers onChange at all, so reaching for it again fails loudly rather than quietly regrowing the subscription.
beginRamp still asked volumeFor("music") whether there was anything to
ramp, and volumeFor folds in the focus duck. So a play that landed while
the page was unfocused with muteOnBlur on read as a silent channel: the
ramp was skipped, the Howl registered at once, and the theme arrived at
full level the moment the player came back. That is the defect the
per-tick read removed, surviving at the last place that still captured a
level rather than reading one.
Narrow, since playback starts from a pointer gesture, but reachable --
the click arms it and the stream is still loading when the player
alt-tabs, so "play" fires unfocused.
isAudible is the right question here. It reads the master and category
sliders and nothing else, so it answers "has the player turned this
channel off", where volumeFor answers "is it silent this instant". A
ducked channel should still ramp: the tick already writes it silent while
it is ducked and hands it back at the position the ramp reached.
The test double now models the two separately, because the distinction is
the entire point -- a level of zero no longer implies the channel is off.

play() pushes an entry onto `active` and binds end/stop to release it. A cue that never starts fires neither, so its entry stays and that channel is a voice poorer for the rest of the session. The per-channel budgets are new, which sharpens what used to be harmless: alerts holds 3 and ambience 2, so a handful of failures takes a channel to silence. It degrades quietly rather than erroring, which is the bad kind. The two error events need different handling, which the Howler source settles rather than intuition: - playerror is always emitted with the sound's own id (howler.js:930, :948, :967), so it matches an id-bound listener and joins end and stop in releaseOnce. It also means a failed preview cue resolves its promise instead of hanging. - loaderror is emitted with a null id everywhere except a media-element error (:662, :682, :710, :2424, :2464). _emit dispatches on `!events[i].id || events[i].id === id`, so an id-bound listener never matches a null emit -- it would have been dead code for exactly the cases that matter. It is bound per Howl instead, with no id, and clears every active entry for that Howl at once. A discarded Howl also leaves the cache. Left in, the next play() of that cue would hand back the same dead one, and play() on something unloaded queues and returns an id, so it would push another entry nothing can release -- the channel bleeding a voice per attempt until it fell silent. Dropping it means the next play builds a fresh Howl and refetches. That is the deliberate choice between retrying and writing the cue off: a blip on the CDN should not silence a cue for the rest of the session, and these files are small. The cost is that a genuinely missing file is refetched once per play rather than once, which is wasted work but bounded by how often the cue fires and self-cleaning each time.
hadTrainStation is keyed by unit id and cleared when a structure goes inactive, but that clear only runs if an inactive update reaches handleTrainStation. One that leaves view without ever delivering it kept its entry for the rest of the session. Not wrong, just a leak. A sweep every 100 ticks -- ten seconds or so -- drops entries whose unit GameView no longer has, or has as inactive. No cue can be lost to this. GameView removes a unit only once it is inactive, queuing the id on the tick isActive() goes false, so both arms of that test mean destroyed and a destroyed structure never comes back to gain a station. The sweep applies exactly the condition handleTrainStation already does, catching the units whose final update never reached it. Nor can one be replayed, which is the reason handleTrainStation tests `prev === false` rather than a falsy value: a structure whose entry has gone reads as undefined, not false, so it is treated like one first seen with a station already and stays silent. Both properties are now covered by tests, since the second is easy to break by "simplifying" that check.

Rebased onto
mainafter PR A (#5341) landed the settings cogwheel. That PR deleted the in-gameSettingsModalhandlers this branch had addedplaySliderTickto, so the tick moved toUserSettingModal, where the sliders now live.The rest addresses the review findings, most of which were levels and gain staging rather than logic.
Per-channel mixer. New
AudioMixerowns all six channels (master / music / effects / alerts / ambience / interface), the focus duck and the concurrency budgets. It is a page-level singleton, so the home page's menu theme and a running game'sSoundManagershare it. It followsUserSettingsdirectly throughUSER_SETTINGS_CHANGED_EVENTrather than anEventBus, because the page and a game have different bus instances and volume has to reach both. The Audio settings tab (coordinator-B's lane) drives it.Levels.
EFFECTS_MASTER_GAIN(−5 dB) is gone. It was written when the delivery peaked at −0.1 dBFS; the designer has since re-bounced 2 dB down, so it was stacking to roughly −7 dB.gameplay.mp3at +0.11 dBTP andmenu-theme.mp3at +0.19.ka-chingandatom-hit, the two old cues kept for want of replacements, were 9 and 6 dB below the new set and have been matched to it.Ambience now follows the designer's spec instead of playing flat at cue level: a zoom envelope peaking at −20 dB below the channel at maximum zoom and fading to silence at the threshold. It also no longer refuses to start when the volume was 0 at load — the common path, given both sliders defaulted to 0.
Concurrency is per channel (effects 6, alerts 3, interface 4, ambience 2) rather than one pool of 8, so a burst of combat cannot silence an inbound nuke warning. Evicted cues fade over 60 ms instead of being cut.
Menu music registers with the mixer, so the music slider reaches it live — it previously snapshotted the volume once and could not be turned down or muted without a page reload — and fades out into a game rather than hard-cutting.
Defaults are no longer 0 (master 1.0, music 0.5, effects 0.7, alerts 0.8, ambience 0.4, interface 0.5), with read-through from the two legacy keys so existing players keep what they chose. A stored 0 stays 0.
