AndroidAudioRecordingSession

class AndroidAudioRecordingSession(context: Context, requestedDevice: AudioDevice.Input?, format: AudioFormat = DefaultAndroidRecordingAudioFormat) : BaseAudioRecordingSession

Android implementation of BaseAudioRecordingSession.

Emulator note: Recordings made through the Android emulator's QEMU audio bridge can sound noisy or grainy because the bridge resamples the host microphone signal (see GitHub issue #1). For best emulator quality:

request a format that matches the host (AudioQuality.High = 48 kHz / Int16 / mono / interleaved is the safest default), and
launch the AVD with --audio-backend coreaudio (macOS) or --audio-backend pulse (Linux) so the bridge bypasses extra resampling.

Real production audio quality should always be validated on a physical device.

Constructors

AndroidAudioRecordingSession

constructor(context: Context, requestedDevice: AudioDevice.Input?, format: AudioFormat = DefaultAndroidRecordingAudioFormat)

Properties

audioFlow

open override val audioFlow: StateFlow<AudioFlow?>

A flow that emits audio data chunks as ByteArrays while recording.

state

open override val state: StateFlow<AudioRecordingSession.State>

A flow that emits the current state of the recording.

Functions

pause

open suspend override fun pause()

Pauses recording while preserving the captured buffer, the live recording job, and the publicly exposed AudioFlow. Calling resume appends further chunks to the same hot flow, so consumers see one continuous stream.

reset

open override fun reset()

resume

open suspend override fun resume()

Resumes a recording previously paused. The buffered chunks from before the pause remain in the audio flow; new chunks are appended to the same hot flow.

start

open suspend override fun start()

Starts the recording. Sets the state to RECORDING.

stop

open override fun stop()

Stops the current recording. Sets the state to STOPPED.
