Thread: Audio stream explanations for Windows and Linux

Hi,

I am familiar with audio streams and processing them when using an MCU, now I am trying to catch the audio stream from the sound processor and use it. Can anyone please explain how to do this? There must be a function of some sort which takes what ever is going through the sound processor and after that I am able to process it and send it to speakers? Perhaps the function catches it before the sound processor or it manipulates the sound processor itself? Can someone please explain how this happens.

For Linux/FreeBSD I recomend ALSA and ffmpeg (lav libraries)... You can try to use SDL sound libraries as well...

You need to read the documentation, write some code, link with the libraries and voilà!

What I am interested in is how does the function access the sound processor and connect this to the OS. Its probably connected to the driver, so in reality we access the driver.
