Re: [LAU] Recording a video with High quality audio

Thank you for your help; this is a lot to take in, though I am not

adverse to working on the command line, and many times I prefer it.

In your first example, it seems I need to substitute something
for "jackaudiosrc". What might I put there?

Also, I am surprised to see the use of the "!" character as
opposed to the pipe "|". Is the "!" particular to bash?

I am taking a look at the documentation. Thanks again.
