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.

I can reproduce this in Windows own example code: Im using the CaptureSharedEventDriven sample. In principle it works correctly, but it breaks whenever I try to debug it, after continuing from a breakpoint. Hr = pProps->GetValue(PKEY_Device_FriendlyName, &varName) I am writing a program that captures the output on a Windows device using WASAPI loopback capture. Get the endpoint's friendly-name property. Initialize the container for property value. Recorder Audio Capture Box, Video Capture Converter Audio Video Usb 2.

Each iteration prints the name of an endpoint device. Hr = pEnumerator->EnumAudioEndpoints(eCapture, DEVICE_STATE_ACTIVE, &pCollection) Run it immediately after the successful installation. Hr = CoCreateInstance(CLSID_MMDeviceEnumerator, NULL, CLSCTX_ALL, IID_IMMDeviceEnumerator, (void**)&pEnumerator) Free download the Microsoft screen recording utility on Windows 10/8/7 computer. and endpoint ID string of each endpoint device. 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.
