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.

A fade needs its own gain line

A sleep timer that ends on a bare pause() chops the music off. Ramping to silence first is a two-line change with three ways to get it wrong. The rule that avoids all three: the fade gets its own gain line, multiplied with the user's volume at the point the value reaches the audio path.

interface MediaPlayerInterface {
    var volume: Float           // the user's level — reported back to the UI
    var sleepFadeFactor: Float  // 0f..1f, the fade's own line
}
  • Android (Media3): a small AudioProcessor in the chain, one instance per player, all reading the same @Volatile field: arrayOf(crossfadeFilter, sleepFade).
  • Desktop: engines commonly expose two levels — a device-mixer level and a software level. Put the fade on one and the crossfade ramp on the other; they then multiply and neither has to know the other exists.

Traps

Ramping the user's volume. It is the obvious implementation and it is wrong twice over. That value is reported back through the volume-changed callback, so the slider visibly crawls to zero while the user watches. Worse, if the process ends mid-fade the persisted level is now near zero: the app comes back silent with a full-looking slider, and no code path restores it because nothing knows a fade was interrupted. The user's level must be the one thing a fade never writes.

Pausing the instant the ramp reaches zero. Gain is applied ahead of a buffered output stage. Several hundred milliseconds of already-attenuated-but-not-silent audio is still queued when the ramp finishes, so the pause cuts it at a clearly audible level. Hold silence for a short tail before pausing:

delay(remaining - fadeMs - tailMs)
fadeOutForSleep(fadeMs)     // ramps to 0
delay(tailMs)               // let the tail drain
player.pause()

Tune the tail against the platform's own output buffer; measure by ear at the boundary rather than copying a number. Both fade and tail must be clamped to fit inside what is left (fadeMs.coerceAtMost(remaining), then tailMs.coerceAtMost(remaining - fadeMs)), or an "end of current song" timer runs past the end of the song and pauses inside the next.

Restoring the gain from the caller, right after pause(). This is the subtle one. pause() is asynchronous and suspends partway through (committing a crossfade joins a job). A single-threaded dispatcher therefore does not order "pause, then restore": the suspension releases the thread, the queued restore runs first, and the mixer re-opens over the last of the audio — a short swell right after the fade. The restore belongs in the player adapter's own completion path:

override fun pause() {
    scope.launch {
        try { /* commit any fade, then pause */ }
        finally { internalSleepFadeFactor = 1f }   // playback has genuinely stopped here
    }
}

Putting the restore on the happy path instead of in finally. The block above can throw or be cancelled — committing a crossfade joins a job that may itself be cancelled. Any path that skips the restore leaves every sample multiplied by ~0 for the rest of the process, with a full volume slider and no way back. finally is not defensive style here; it is the only correct placement.

Forgetting an early-return branch of pause(). A handoff to a remote-playback session typically returns before the coroutine is ever launched. That branch must clear the factor inline, or the attenuation outlives the remote session: the processor is still in the local chain and keeps multiplying by ~0 when playback comes back.

The timer's own finally must not double-restore. The caller still needs a restore for the cancelled path (the user turned the timer off, the scope went away mid-fade). Guard it so the completed path leaves the job to the adapter:

finally { if (!stoppedPlayback) player.sleepFadeFactor = 1f }

Capturing the gain instead of reading it fresh. The processor must read the field on every buffer, not once at configure time — otherwise a fade that starts, or keeps advancing, in the middle of a crossfade never reaches the output. Same reason the desktop setter re-reads the field inside the queued task rather than capturing the argument: if the queue backs up, pending writes collapse onto the newest value instead of replaying a stale ramp.

Making the processor inactive at full gain. A processor that reports isActive = false is dropped from the chain and is not reconsulted until the next flush — by which time the timer has already stopped playback. Keep it always active and make the full-gain case a bulk copy:

override fun isActive() = true

override fun queueInput(input: ByteBuffer) {
    val out = replaceOutputBuffer(input.remaining())
    val g = gain()
    if (g >= 1f) { out.put(input); out.flip(); return }   // every buffer, all playback
    input.order(ByteOrder.nativeOrder())
    while (input.remaining() >= 2) out.putShort((input.short * g).toInt().toShort())
    while (input.hasRemaining()) out.put(input.get())     // consume ALL of it
    out.flip()
}

Leaving even one byte unconsumed makes the pipeline re-offer the same buffer forever, having made no progress.

Linear ramps and unbounded step counts. Use the same equal-power (cosine) curve as a crossfade — cos(progress * PI / 2) — because loudness is perceived logarithmically and a linear ramp sounds like it drops away early then lingers. And clamp the step count to the duration: 50 steps at a 1 ms floor takes 50 ms no matter what duration was requested, so a 1-second fade silently becomes an instant one.

val steps = nominalSteps.toLong().coerceAtMost(durationMs).toInt()
val delayPerStep = (durationMs / steps).coerceAtLeast(1L)

Verifying it

  • Watch the volume slider through a full fade. It must not move.
  • Kill the process mid-fade, relaunch, press play: audio at the user's level, immediately.
  • Let a timer complete, then press play: full level, no swell, no residual attenuation.
  • Cancel a timer mid-fade: level restored within a step or two.
  • If the platform reports the applied gain, log it once per second during the ramp and confirm it reaches 0 before the pause and 1 after it, never between.

# A fade needs its own gain line

A sleep timer that ends on a bare `pause()` chops the music off. Ramping to silence first
is a two-line change with three ways to get it wrong. The rule that avoids all three: the
fade gets **its own gain line**, multiplied with the user's volume at the point the value
reaches the audio path.

```kotlin
interface MediaPlayerInterface {
    var volume: Float           // the user's level — reported back to the UI
    var sleepFadeFactor: Float  // 0f..1f, the fade's own line
}
```

- **Android (Media3):** a small `AudioProcessor` in the chain, one instance per player, all
  reading the same `@Volatile` field: `arrayOf(crossfadeFilter, sleepFade)`.
- **Desktop:** engines commonly expose two levels — a device-mixer level and a software
  level. Put the fade on one and the crossfade ramp on the other; they then multiply and
  neither has to know the other exists.

## Traps

**Ramping the user's volume.** It is the obvious implementation and it is wrong twice over.
That value is reported back through the volume-changed callback, so the slider visibly
crawls to zero while the user watches. Worse, if the process ends mid-fade the persisted
level is now near zero: the app comes back silent with a full-looking slider, and no code
path restores it because nothing knows a fade was interrupted. The user's level must be
the one thing a fade never writes.

**Pausing the instant the ramp reaches zero.** Gain is applied *ahead* of a buffered output
stage. Several hundred milliseconds of already-attenuated-but-not-silent audio is still
queued when the ramp finishes, so the pause cuts it at a clearly audible level. Hold
silence for a short tail before pausing:

```kotlin
delay(remaining - fadeMs - tailMs)
fadeOutForSleep(fadeMs)     // ramps to 0
delay(tailMs)               // let the tail drain
player.pause()
```

Tune the tail against the platform's own output buffer; measure by ear at the boundary
rather than copying a number. Both fade and tail must be **clamped to fit inside what is
left** (`fadeMs.coerceAtMost(remaining)`, then `tailMs.coerceAtMost(remaining - fadeMs)`),
or an "end of current song" timer runs past the end of the song and pauses inside the next.

**Restoring the gain from the caller, right after `pause()`.** This is the subtle one.
`pause()` is asynchronous *and* suspends partway through (committing a crossfade joins a
job). A single-threaded dispatcher therefore does **not** order "pause, then restore": the
suspension releases the thread, the queued restore runs first, and the mixer re-opens over
the last of the audio — a short swell right after the fade. The restore belongs in the
player adapter's own completion path:

```kotlin
override fun pause() {
    scope.launch {
        try { /* commit any fade, then pause */ }
        finally { internalSleepFadeFactor = 1f }   // playback has genuinely stopped here
    }
}
```

**Putting the restore on the happy path instead of in `finally`.** The block above can throw
or be cancelled — committing a crossfade joins a job that may itself be cancelled. Any path
that skips the restore leaves every sample multiplied by ~0 for the rest of the process,

    input.order(ByteOrder.nativeOrder())
    while (input.remaining() >= 2) out.putShort((input.short * g).toInt().toShort())
