Last week we learned how to make simple video screencasts on Linux with recordMyDesktop. Today we’re going to record audio from a microphone, get acquainted with JACK, and convert MyDesktop’s Ogg files into AVI formats.
Even the most low-budget onboard sound chip should have a microphone input. Plug in your mic, and then make sure it is enabled in your mixer. If your system has only a single sound card, enter hw:0,0 as the recording device in your recordMyDesktop configuration. And that’s all you need to do.
