just used sed
to process an audio file
@Miredly so this sed script takes a wav file converted to a text representation, converts it to *effective* 1 bit pcm (actually 8 bit but everything is -128 or +127), then its converted back to wav and sent to aplay
@hierarchon it converted a file to a text representation
and then used a sed script to process it into effective 1 bit pcm by replacing all lines with the sign of that line
...and it just turned it into a one liner, to do this to an arbitrary audio file
