Ever heard the story of why CDs can hold 74 minutes of audio? This goes to the question of what CD quality actually means (sample rate and bit depth all contribute to the amount of data needing to be stored).
Well it's all Beethoven's fault apparently, more specifically, his 9th (and last) Symphony.

They use the acronym DAW, which refers to a Digital Audio Workstation. It's what I use to compose, edit and produce my music. Think of it like a word processor or video editor for sound.
