My headset was plugged in into internal audio device, capture level sets to maximum and used command:arecord -c2 -f cd -d 10 internalaudiodevicenoise. Wav. Yes, guys, it's linux! :-). So pretty noise generated by very cheap device!as you can see from the console command, audiofile have the next format: signed 16 bit little endian, rate 44100 hz, stereo, duration 10 seconds.
