Can some1 tell me what are the PCM input/ouput device names (like hw)
for
a speaker(output) and a mic(input)?
ohh and does can some1 tell me what is the vertical axis of the
oscilloscope.py
I tried specifying pcm1c listed in card 0 folder which said its a mic
…but it gives an error that the device is not found . The program
audio_to_file only works with hw:0 specified …
What exactly is hw:0 ? i.e what’s the audio that is considered ? Here is
it possible to give audio through the mic in real time?
