AudioSessionManager

Android implementation of AudioSessionManager.

Manages AudioFocus for coordinated player/recorder usage.

Cross-platform audio session manager (ADR-016).

Coordinates audio session/focus for player and recorder to work together. Without coordination, iOS AVAudioSession and Android AudioFocus race conditions cause silent playback or dropped recordings.

Quick Start

Kotlin

AudioSessionManager.configure(AudioMode.PLAY_AND_RECORD, echoCancellation = true)

AudioSessionManager.addFocusListener(object : AudioFocusListener {
    override fun onFocusGained() { player.play() }
    override fun onFocusLost(transient: Boolean) { player.pause() }
    override fun onDuck() { player.setVolume(0.3f) }
})

AudioSessionManager.deactivate()

Swift

AudioSessionManager.configure(mode: .playAndRecord, echoCancellation: true)
// On iOS, also exposes hardwareSampleRate for ADR-017 passthrough
let hwRate = AudioSessionManager.hardwareSampleRate

Manages AVAudioSession configuration for coordinated player/recorder usage.

Desktop-JVM audio session manager. The desktop OS audio stack has no app-level audio-session/focus concept (that's a mobile notion, ADR-016), so there is no session to race: configure just records the mode and reports active. Focus listeners are tracked for contract parity but never fire (no system focus events on desktop). System AEC and shared session ids are mobile-only.
