Capture audio from sound card using ALSA - Simulink
https://www.mathworks.com/help/supportpkg/raspberrypi/ref/alsaaudiocapture.html
The ALSA Audio Capture block determines the sample time (T s) from the samples per audio channel (N) and sampling frequency (Fs). T s = N / Fs. For example, if N is 4410 samples and Fs is 44,100 Hz, the block sample time is 4410/44,100 = …

alsa - how to capture audio by using dummy sound card ...
https://stackoverflow.com/questions/58584405/how-to-capture-audio-by-using-dummy-sound-card-driver
I hope to know how to capture audio by using dummy sound card driver. I'm thinking how to implement the steps below. we play audio in ubuntu, however the audio is just played through dummy sound card driver, to capture audio stream. captured audio is sent to windows through network. audio is actually played in windows.
