I'm working with an external sound card device that have 4 microphone inputs and it's conneceted by usb to my laptop. So I need to take samples of the audio that came from the microphones and do a bar chart or any graphic that shows which mic capture first, second, third and fourth the sound! I had thought to capture that information in a csv file and then do the chart? Any help please?
Thank you!!
You might try the Audio Analysis section of the Python Wiki. There seem to be some toolkits for audio processing.
