I am new to using Alsa API for sound processing. I am trying to use Alsa API to receive an input, process and send it back to the output port. I have set the buffer size of 512.
Source = alsaaudio.PCM(alsaaudio.PCM_CAPTURE, device = cards, channels = 2, rate = 48000...
How can I implement a signal processing algorithm (filtering, transformed) using simulation data (stored in a file) or acquired in real time? I want to do this on the Rasberry Pi 4. I have no idea how to do it, some examples like a low pass filter algorithm or FIR, IIR
Or a concrete example of...
