If audio recording is something that you see yourself doing for the foreseeable future,
I would suggest downloading Pro Tools Intro which is free from Avid, and works on both
Windows as well as Mac computers.
If you are in fact heading in this direction with passion and purpose, you are being hurled into
the need to acquire a Digital Audio Workstation (DAW), this is a good thing!
Apple's Garage Band comes free with Mac computers, iPads, and iPhones, and is actually an
introduction to its big brother DAW Logic Audio.
It takes multi track recording capability to overdub and mix effectively so getting started
with a free DAW platform would be very beneficial for your current and future recording
needs.
