I have TDM8 mic array. All works fine. But signal which I get from arecord command is shifted to 65000 approximately. This is not problem 'cos I correct shift programmatically. And recently I noticed that at high sound volume I get very bad picture.
It is very similar to overflowing in somewhere. And I suppose this overflowing is connected to signal shift. How I can adjust Nano to remove this signal offset? I have found that fsync width can enlarge and make smaller signal offset, but not so small as I wish.
Thank you in advance!
