Use when a fade drags the volume slider down in the UI, when the app comes back permanently silent with a full slider, when a fade still ends in an audible click, or when audio briefly swells back after a fade completes.\n---\n\n# A fade needs its own gain line\n\nA sleep timer that ends on a bare `pause()` chops the music off. Ramping to silence first\nis a two-line change with three ways to get it wrong. The rule that avoids all three: the\nfade gets **its own gain line**, multiplied with the user's volume at the point the value\nreaches the audio path.\n\n```kotlin\ninterface MediaPlayerInterface {\n    var volume: Float           // the user's level — reported back to the UI\n    var sleepFadeFactor: Float  // 0f..1f, the fade's own line\n}\n```\n\n- **Android (Media3):** a small `AudioProcessor` in the chain, one instance per player, all\n  reading the same `@Volatile` field: `arrayOf(crossfadeFilter, sleepFade)`.\n- **Desktop:** engines commonly expose two levels — a device-mixer level and a software\n  level. Put the fade on one and the crossfade ramp on the other; they then multiply and\n  neither has to know the other exists.\n\n## Traps\n\n**Ramping the user's volume.** It is the obvious implementation and it is wrong twice over.\nThat value is reported back through the volume-changed callback, so the slider visibly\ncrawls to zero while the user watches. Worse, if the process ends mid-fade the persisted\nlevel is now near zero: the app comes back silent with a full-looking slider, and no code\npath restores it because nothing knows a fade was interrupted. The user's level must be\nthe one thing a fade never writes.\n\n**Pausing the instant the ramp reaches zero.** Gain is applied *ahead* of a buffered output\nstage. Several hundred milliseconds of already-attenuated-but-not-silent audio is still\nqueued when the ramp finishes, so the pause cuts it at a clearly audible level. Hold\nsilence for a short tail before pausing:\n\n```kotlin\ndelay(remaining - fadeMs - tailMs)\nfadeOutForSleep(fadeMs)     // ramps to 0\ndelay(tailMs)               // let the tail drain\nplayer.pause()\n```\n\nTune the tail against the platform's own output buffer; measure by ear at the boundary\nrather than copying a number. Both fade and tail must be **clamped to fit inside what is\nleft** (`fadeMs.coerceAtMost(remaining)`, then `tailMs.coerceAtMost(remaining - fadeMs)`),\nor an \"end of current song\" timer runs past the end of the song and pauses inside the next.\n\n**Restoring the gain from the caller, right after `pause()`.** This is the subtle one.\n`pause()` is asynchronous *and* suspends partway through (committing a crossfade joins a\njob). A single-threaded dispatcher therefore does **not** order \"pause, then restore\": the\nsuspension releases the thread, the queued restore runs first, and the mixer re-opens over\nthe last of the audio — a short swell right after the fade. The restore belongs in the\nplayer adapter's own completion path:\n\n```kotlin\noverride fun pause() {\n    scope.launch {\n        try { /* commit any fade, then pause */ }\n        finally { internalSleepFadeFactor = 1f }   // playback has genuinely stopped here\n    }\n}\n```\n\n**Putting the restore on the happy path instead of in `finally`.** The block above can throw\nor be cancelled — committing a crossfade joins a job that may itself be cancelled. Any path\nthat skips the restore leaves every sample multiplied by ~0 for the rest of the process,\nwith a full volume slider and no way back. `finally` is not defensive style here; it is the\nonly correct placement.\n\n**Forgetting an early-return branch of `pause()`.** A handoff to a remote-playback session\ntypically returns before the coroutine is ever launched. That branch must clear the factor\ninline, or the attenuation outlives the remote session: the processor is still in the local\nchain and keeps multiplying by ~0 when playback comes back.\n\n**The timer's own `finally` must not double-restore.** The caller still needs a restore for\nthe *cancelled* path (the user turned the timer off, the scope went away mid-fade). Guard it\nso the completed path leaves the job to the adapter:\n\n```kotlin\nfinally { if (!stoppedPlayback) player.sleepFadeFactor = 1f }\n```\n\n**Capturing the gain instead of reading it fresh.** The processor must read the field on\nevery buffer, not once at configure time — otherwise a fade that starts, or keeps advancing,\nin the middle of a crossfade never reaches the output. Same reason the desktop setter\nre-reads the field inside the queued task rather than capturing the argument: if the queue\nbacks up, pending writes collapse onto the newest value instead of replaying a stale ramp.\n\n**Making the processor inactive at full gain.** A processor that reports `isActive = false`\nis dropped from the chain and is not reconsulted until the next flush — by which time the\ntimer has already stopped playback. Keep it always active and make the full-gain case a\nbulk copy:\n\n```kotlin\noverride fun isActive() = true\n\noverride fun queueInput(input: ByteBuffer) {\n    val out = replaceOutputBuffer(input.remaining())\n    val g = gain()\n    if (g >= 1f) { out.put(input); out.flip(); return }   // every buffer, all playback\n    input.order(ByteOrder.nativeOrder())\n    while (input.remaining() >= 2) out.putShort((input.short * g).toInt().toShort())\n    while (input.hasRemaining()) out.put(input.get())     // consume ALL of it\n    out.flip()\n}\n```\n\nLeaving even one byte unconsumed makes the pipeline re-offer the same buffer forever,\nhaving made no progress.\n\n**Linear ramps and unbounded step counts.** Use the same equal-power (cosine) curve as a\ncrossfade — `cos(progress * PI / 2)` — because loudness is perceived logarithmically and a\nlinear ramp sounds like it drops away early then lingers. And clamp the step count to the\nduration: 50 steps at a 1 ms floor takes 50 ms no matter what duration was requested, so a\n1-second fade silently becomes an instant one.\n\n```kotlin\nval steps = nominalSteps.toLong().coerceAtMost(durationMs).toInt()\nval delayPerStep = (durationMs / steps).coerceAtLeast(1L)\n```\n\n## Verifying it\n\n- Watch the volume slider through a full fade. It must not move.\n- Kill the process mid-fade, relaunch, press play: audio at the user's level, immediately.\n- Let a timer complete, then press play: full level, no swell, no residual attenuation.\n- Cancel a timer mid-fade: level restored within a step or two.\n- If the platform reports the applied gain, log it once per second during the ramp and\n  confirm it reaches 0 *before* the pause and 1 *after* it, never between.\n","tagline":"Implement a programmatic audio fade — a sleep timer, an alarm ramp, a duck — on a gain line of its own instead of the user's volume, and restore that gain from the player's own completion path.

Preserve the core workflow, adapt paths to this repo, and keep the rule scoped to tasks where it is relevant. Skill purpose: Implement a programmatic audio fade — a sleep timer, an alarm ramp, a duck — on a gain line of its own instead of the user's volume, and restore that gain from the player's own completion path. Use when a fade drags the volume slider down in the UI, when the app comes back permanently silent with a full slider, when a fade still ends in an audible click, or when audio briefly swells back after a fade completes.
