I am also interested in this tried tunning any available parameter from
with close to a zero change in the noise level.
I tried with this as the background noise which is quite stationary and I expected some change in the noise levels but didn’t notice almost any difference.
Used arecord to record the a wav file
arecord --device=hw:1 --format=S16_LE 1.wav
and here are all the parameters I tried
