I am trying to record audio using the MAX4466 op-amp and VS1053 shield that I bought from Kynix. I am able to record audio by connecting OUT --> MICP, GND --> MICN, GND -> GND.*
The recorded audio seems to have a very low gain i.e. I am barely able to hear what has been recorded in a room. I tried varying the gain using a potentiometer.* The recordings are generally noisy so I’m not able to listen to what is actually being recorded.*
The recordings are marred by some noise (Link for the*sample). While I am not trying to achieve high quality audio using an arduino + a breakout on a breadboard, I would like to record any conversation within a few feet (of course with the consent of people being recorded).*
My questions are:
a) How do I avoid the noise that is affecting the quality of the recording?
b) How do I improve the gain of the recording so that I am able to hear something when I play the recorded file?
c) If it is not possible using the MAX4466 breakout, is there an alternative to record the audio?
