Ts3 audio loopback windows 7#
That way there are never any “nothing is playing” glitches, because there’s always something playing.ĮDIT : Updated loopback-capture.exe to ignore the glitch flag on the first packet, since Windows 7 sets it. One way is to ignore glitches then if you stop a song, wait a few seconds, and start it again, then the recorded signal will omit the wait and abut the two “audio is playing” portions.īut my particular favorite way of handling this is to run silence.exe. There are a couple of other possible ways to handle this. Eventually the song started up again, and WASAPI dutifully reported that there was a glitch detected. When the song stopped, no more data was available to capture. Windows Vista provides digital rights management (DRM). WASAPI supports loopback recording regardless of whether the audio hardware contains a loopback device, or whether the user has enabled the device. The flag in question is AUDCLNT_BUFFERFLAGS_DATA_DISCONTINUITY. Finally, to select the loopback device to be the default capture device, right-click the device and click Set as Default Device. IAudioCaptureClient::GetBuffer set flags to 0x00000001 on pass 5381 after 1088829 frames You’ll get this output when you start it back up: >loopback-capture While loopback-capture is running, stop the song, and then start it again. When nothing is playing, there is nothing to capture.įor example, play a song, and then run loopback-capture. So this app creates its own waitable timer.Īnother oddity is that WASAPI will only push data down to the render endpoint when there are active streams. One is that “event mode” doesn’t work for loopback capture you can call pAudioClient->Initialize(… AUDCLNT_STREAMFLAGS_LOOPBACK | AUDCLNT_STREAMFLAGS_EVENTCALLBACK, … ), you can call pAudioClient->SetEventHandle(…), and everything will succeed… but the “data is ready” event will never fire. There are a couple of oddities for WASAPI loopback capture. int-16 attempts to coerce data to 16-bit integer format file saves the output to a file (loopback-capture.wav if omitted)) device captures from the specified device (default if omitted) list-devices displays the long names of all active playback devices. This allows you to record the sound that is coming out of your speakers.ĭownload loopback-capture.exe >loopback-capture -? This post is a sample WASAPI loopback capture app.

In a previous post I showed how to play silence to a given audio device and hinted at a possible application.
