![]() If a custom audio device has been set via SetCustomAudioDevice, this will also trigger the following IAudioDevice methods in order: More. This method must be called whenever a change in output device happens in the custom audio device to let the SDK perform the necessary corrections for the new device. This method must be called whenever a change in input device happens in the custom audio device to let the SDK perform the necessary corrections for the new device. Sets an instance of the IAudioDevice interface as the virtual audio device for a custom audio driver used by all publishers and subscribers. SetCustomAudioDevice ( Context context, IAudioDevice audioDevice) Gets the system default audio output device. Gets the system default audio input device. Sets the output audio device to be used by all subscribers. SetOutputAudioDevice ( OutputAudioDevice device) Sets the input audio device to be used by all subscribers. SetInputAudioDevice ( InputAudioDevice device) ![]() Returns a list of available audio output devices on the system. Returns a list of available audio input devices on the system. See EnumerateOutputAudioDevices and SetOutputAudioDevice. Represents an output audio device (such as headphones or speakers) available on the Windows system. This instance can be disposed when no longer used to release unmanaged resources. This object sends events when a system input or output audio device is added or removed, and when the default system input or output audio device changes. Represents a subscription to system audio device notifications. See EnumerateInputAudioDevices and SetInputAudioDevice. Represents an input audio device (such as a microphone) available on the Windows system. This class is used to both read and write audio samples in order for them to be rendered or sent to remote peers. In JavaScript, the MediaDevices.enumerateDevices() method can be used to enumerate the media devices and find a device ID to pass to fromMicrophone(.).A class that includes methods for setting the audio device to be used by publishers and subscribers.Īn audio bus used for all publisher and subscribers. WithOptions:AVAudioSessionCategoryOptionAllowBluetooth error:NULL] Įnables the use of a Bluetooth headset for a speech-enabled app. Apps that use the SDK can influence audio routing through the AVAudioSession Framework.įor example, the instruction setCategory:AVAudioSessionCategoryRecord Audio device IDs on iOSĪudio device selection with the Speech SDK isn't supported on iOS. Return a non-mutable copy of the arrayĬFArrayRef immutableInputDeviceArray = CFArra圜reateCopy(kCFAllocatorDefault, inputDeviceArray) įor example, the UID for the built-in microphone is BuiltInMicrophoneDevice.

Hr = pProps->GetValue(PKEY_Device_FriendlyName, &varName) Get the endpoint's friendly-name property. Initialize the container for property value. Each iteration prints the name of an endpoint device. Hr = pEnumerator->EnumAudioEndpoints(eCapture, DEVICE_STATE_ACTIVE, &pCollection) Hr = CoCreateInstance(CLSID_MMDeviceEnumerator, NULL, CLSCTX_ALL, IID_IMMDeviceEnumerator, (void**)&pEnumerator) However, if you cannot avoid using separate devices and you experience. Choosing separate devices might cause audio echoing during a call. For best results, select the same device for both the speaker and microphone. ![]() and endpoint ID string of each endpoint device. In Audio Device options, in the Select the device you want to use for audio calls list, select the audio device you want to use. This function enumerates all active (plugged in) audio The following code sample illustrates how to use it to enumerate audio devices in C++: #include Ĭonst CLSID CLSID_MMDeviceEnumerator = _uuidof(MMDeviceEnumerator) Ĭonst IID IID_IMMDeviceEnumerator = _uuidof(IMMDeviceEnumerator) Ĭonstexpr auto REFTIMES_PER_SEC = (10000000 * 25) Ĭonstexpr auto REFTIMES_PER_MILLISEC = 10000 ĬoInitializeEx(NULL, COINIT_MULTITHREADED) Audio device IDs on Windows for desktop applicationsĪudio device endpoint ID strings can be retrieved from the IMMDevice object in Windows for desktop applications. Microphone use isn't available for JavaScript running in Node.js.
