Method Detail

setSampleRate

public JavaAudioDeviceModule.Builder setSampleRate(int sampleRate)

Call this method if the default handling of querying the native sample rate shall be overridden. Can be useful on some devices where the available Android APIs are known to return invalid results.

setAudioSource

public JavaAudioDeviceModule.Builder setAudioSource(int audioSource)

Call this to change the audio source. The argument should be one of the values from android.media.MediaRecorder.AudioSource. The default is AudioSource.VOICE_COMMUNICATION.

setAudioTrackErrorCallback

public JavaAudioDeviceModule.Builder setAudioTrackErrorCallback(JavaAudioDeviceModule.AudioTrackErrorCallback audioTrackErrorCallback)

Set a callback to retrieve errors from the AudioTrack.

setAudioRecordErrorCallback

public JavaAudioDeviceModule.Builder setAudioRecordErrorCallback(JavaAudioDeviceModule.AudioRecordErrorCallback audioRecordErrorCallback)

Set a callback to retrieve errors from the AudioRecord.

setSamplesReadyCallback

public JavaAudioDeviceModule.Builder setSamplesReadyCallback(JavaAudioDeviceModule.SamplesReadyCallback samplesReadyCallback)

Set a callback to listen to the raw audio input from the AudioRecord.

setUseHardwareNoiseSuppressor

public JavaAudioDeviceModule.Builder setUseHardwareNoiseSuppressor(boolean useHardwareNoiseSuppressor)

Control if the built-in HW noise suppressor should be used or not. The default is on if it is supported. It is possible to query support by calling isBuiltInNoiseSuppressorSupported().

setUseHardwareAcousticEchoCanceler

public JavaAudioDeviceModule.Builder setUseHardwareAcousticEchoCanceler(boolean useHardwareAcousticEchoCanceler)

Control if the built-in HW acoustic echo canceler should be used or not. The default is on if it is supported. It is possible to query support by calling isBuiltInAcousticEchoCancelerSupported().

setUseStereoInput

public JavaAudioDeviceModule.Builder setUseStereoInput(boolean useStereoInput)

Control if stereo input should be used or not. The default is mono.

setUseStereoOutput

public JavaAudioDeviceModule.Builder setUseStereoOutput(boolean useStereoOutput)

Control if stereo output should be used or not. The default is mono.

createAudioDeviceModule

public AudioDeviceModule createAudioDeviceModule()

Construct an AudioDeviceModule based on the supplied arguments. The caller takes ownership and is responsible for calling release().
