Thanks a lot for the information rakshat and wolfgang.
I have done numerous tes of recording (under openwrt mainly, some on
Debian) each time I have a very noisy background and the voice is not
clear at all. But may be my settings are not good since Rubén just

I have each time only tested with arecord and play back the file on
nano or on desktop with aplay, on nano it appears very weak, we cannot
recognize what was told, on the desktop I cn increase the level but
the background is very noisy and the sound very distorted.
Rubén I don't understand what you mean by correct format ?
I would be very interested to know what other people could have
experienced, am I doing something wrong?
since the post of Rubén, I don't know what to think.
