But this post isn't about that. This post is about me attempting to use the nice headphones Parallels sent me, which have a microphone attached to them. Ubuntu apparently didn't come with any recording software installed, and a quick google search pulled up Audacity, which is so old I remember Eric included it as a case study in The Art of Unix Programming (which I edited back in 2003), so presumably it's reasonably mature by now.
So I plug the thing in, fire up audacity, fiddle with it for 10 minutes until I find out how to get it to listen to/output to the headphones (it's under edit->preferencs->device) and then try to figure out how to get it to record right.
The first time you record something with audacity, you get audio with a pronounced annoying hum. (Yes, from a digital input. No, I dunno how it managed that.) The second and later times you record, the audio is chopped up into maybe quarter-second chunks with noticeable gaps between them. You can go from the chopped up audio back to the annoying hum by exiting and restarting audacity.
Did I mention this project is at least 7 years old?
