I'm using a bare electret cartridge with a 3.9 k resistor from 4.2
volts in from a lithium cell, and a 1 MFD coupling cap. I'd expect to
see something when I tap on it, but nothing.

I think a 1-line script to amixer followed by 1 line to arecord is
what I want. I'd be more comfortable with numbers in binary or hex
than all this parsing of prose.

Wacky idea probably. But most social media sites won't let you post
an mp3 (might be copyrighted) but will let you post videos. So do a
video of the Audacity main window with the cursor moving through the
waveform as the audio is played. Yes, you could capture a screen area

No sound that way though, you'd have to mix in the audio file that
Audacity is playing/displaying. xwd can do screen dumps of a specific

If you only need to do it once Audacity can almost certainly do it.

I'm working on this nifty (heh-heh) MP3 jukebox with a CGI front end.
Part of it scans a directory tree of artists, albums, songs, puts

That seems odd. They don't normally mix I think. You have play devices
0-3 and record devices 0-2.They're separate lists. So device 6 is invalid.
