Linux Audio record and quality comparison

I am starting a project to test the audio performance on linux.

What I need to do is to play the audio on our websystem and check the audio quality (or just check it has audio output) on linux.

1. I am going to record the audio on linux with ffmpeg. Is there any other better choice?


2. I don't know how to (automation) check I recorded is what I played, as well as the quality of recorded audio.
