Maybe I'm do not understand ALSA and how it interoperates with the Delta
1010 properly. I have a couple of basic questions about everything works
under the hood:
ecasound -t:3 -f:24,8,44100 -erc:5,1 -o rec1.wav

Does this set the sampling rate of the Delta 1010 to 44100 Hz and lets
the Delta 1010 do all the down-sampling?
Or does it open the Delta 1010 at it's default sampling rate (96 kHz)
and then save the audio at 44100 Hz (using some kind of a budget
