Hi everyone, can someone tell me how to record an analog audio signal with arduino and plot it in matlab? Thank you

I don't know how to do that, but the Arduino has limited memory, the ADC is only 10 bits, the input has to be biased to capture both the positive and negative halves of the waveform, and I believe there are sample rate limitations.

So, how about recording with your computer's soundcard, and then open the WAV file in MATLAB?.

its been a while since i used matlab, but you used to just be able to use the soundcard to both take in audio, and output audio, directly from matlab.
