Capture audio from sound card using ALSA - Simulink
https://www.mathworks.com/help/supportpkg/beaglebone/ref/alsaaudiocapture.html
Capture the left and right audio channels from the AUDIO IN connector or a stereo sound device using the Advanced Linux Sound Architecture (ALSA) driver framework. The block output emits an N-by-2 frame of int16 values. The width of the frame, 2, corresponds to the left and right audio channels. To determine the sample rate of the block output, divide the Frame size (N) by the …

You can use gtkiostream to implement C++ classes for handling audio with ALSA. For example this ALSA::Capture class allows you to capture audio for processing. To use it you include it into your code : #include "ALSA/ALSA.H" using namespace ALSA; Then you can stream in audio to a matrix (matrix columns are audio channels).

ALSA is a good choice if you are performing low-level audio functions for maximum control and performance or want to make use of special features not supported by other sound APIs. If you already have written an audio application, you may want to add native support for the ALSA sound drivers.

A Minimal Capture Program: This program opens an audio interface for capture, configures it for: stereo, 16 bit, 44.1kHz, interleaved conventional read/write: access. Then its reads a chunk of random data from it, and exits. It: isn't meant to be a real program. From on Paul David's tutorial : http://equalarea.com/paul/alsa-audio.html
