Static Methods
-
addChangeListener(
void callback(String type, String id)) → void - Adds a callback that listens to audio device changes (Added, Removed, Default Changed, etc.).
-
enumAudioMixer(
{AudioRole audioRole = AudioRole.multimedia}) → Future< List< ProcessVolume> ?> - Lists all active application audio sessions (mixers).
-
enumDevices(
AudioDeviceType audioDeviceType, {AudioRole audioRole = AudioRole.multimedia}) → Future< List< AudioDevice> ?> - Returns a Future list of audio devices of a specified type.
-
getDefaultDevice(
AudioDeviceType audioDeviceType, {AudioRole audioRole = AudioRole.multimedia}) → Future< AudioDevice?> - Returns the default audio device for the given AudioDeviceType.
-
getSampleRate(
String deviceID) → Future< int> - Gets the current sample rate (in Hz) of the specified audio device.
-
getVolume(
AudioDeviceType audioDeviceType, {AudioRole audioRole = AudioRole.multimedia}) → Future< double> - Gets the master volume level (0.0 to 1.0) for the current default device of the given type.
-
removeChangeListener(
void callback(String type, String id)) → void - Removes a previously added audio device change listener.
-
setAudioDeviceVolume(
String deviceID, double volume) → Future< int> -
Sets the volume of a specific audio device by its
deviceID. -
setAudioMixerVolume(
int processID, double volume, {AudioRole audioRole = AudioRole.multimedia}) → Future< bool> -
Sets the volume for a specific process identified by
processID. -
setAudioMixerVolumeByPath(
String processPath, double volume, {AudioRole audioRole = AudioRole.multimedia}) → Future< bool> -
Sets the volume for a specific process identified by its executable path
processPath. -
setDefaultDevice(
String deviceID, {bool console = false, bool multimedia = true, bool communications = false}) → Future< int> -
Sets the system default audio device using its
deviceID. -
setSampleRate(
String deviceID, int sampleRate) → Future< bool> - Sets the sample rate (in Hz) for the specified audio device.
-
setupChangeListener(
) → Future< void> - Initializes the audio event listener.
-
setVolume(
double volume, AudioDeviceType audioDeviceType, {AudioRole audioRole = AudioRole.multimedia}) → Future< int> -
Sets the master volume for the default device of the given
audioDeviceType. -
switchDefaultDevice(
AudioDeviceType audioDeviceType, {AudioRole audioRole = AudioRole.multimedia, bool console = false, bool multimedia = true, bool communications = false}) → Future< bool> -
Switches the default device to the next available one, or toggles between available devices.
(Logic depends on implementation of
switchDefaultDevicein native code).
