Method Details

builder

public static JavaAudioDeviceModule.Builder builder(Context context)

isBuiltInAcousticEchoCancelerSupported

public static boolean isBuiltInAcousticEchoCancelerSupported()

Returns true if the device supports built-in HW AEC, and the UUID is approved (some UUIDs can be excluded).

isBuiltInNoiseSuppressorSupported

public static boolean isBuiltInNoiseSuppressorSupported()

Returns true if the device supports built-in HW NS, and the UUID is approved (some UUIDs can be excluded).

getNativeAudioDeviceModulePointer

public long getNativeAudioDeviceModulePointer()

Description copied from interface: AudioDeviceModule

Returns a C++ pointer to a webrtc::AudioDeviceModule. Caller does _not_ take ownership and lifetime is handled through the release() call.

Specified by:

getNativeAudioDeviceModulePointer in interface AudioDeviceModule

release

public void release()

Description copied from interface: AudioDeviceModule

Release resources for this AudioDeviceModule, including native resources. The object should not be used after this call.

Specified by:

release in interface AudioDeviceModule

setSpeakerMute

public void setSpeakerMute(boolean mute)

Description copied from interface: AudioDeviceModule

Control muting/unmuting the speaker.

Specified by:

setSpeakerMute in interface AudioDeviceModule

setMicrophoneMute

public void setMicrophoneMute(boolean mute)

Description copied from interface: AudioDeviceModule

Control muting/unmuting the microphone.

Specified by:

setMicrophoneMute in interface AudioDeviceModule

setNoiseSuppressorEnabled

public boolean setNoiseSuppressorEnabled(boolean enabled)

Description copied from interface: AudioDeviceModule

Enable or disable built in noise suppressor. Returns true if the enabling was successful, otherwise false is returned.

Specified by:

setNoiseSuppressorEnabled in interface AudioDeviceModule

setPreferredInputDevice

@RequiresApi(23)
public void setPreferredInputDevice(AudioDeviceInfo preferredInputDevice)

Start to prefer a specific AudioDeviceInfo device for recording. Typically this should only be used if a client gives an explicit option for choosing a physical device to record from. Otherwise the best-matching device for other parameters will be used. Calling after recording is started may cause a temporary interruption if the audio routing changes.
