Mix it up …

When you have audio from multiple sources, it helps to have a mixer to blend that audio. The Alesis  Multimix 8USB product has many features and is a good workhorse. The USB allows a computer to both record and play through the mixer. So, Audacity is just one step away from recording audio input coming from the mixer.

While this may not be an exciting product, this definitely gets the job done.
