You hit the red record button, audio gets captured from your selected input, and the waveform appears on screen. From there, you can trim, split, fade, normalize, apply effects, and export to almost any format. It handles multi-track recording when you need it, but works equally well as a single-track tool. I’ve been using Audacity for as long as I’ve been making music, and I still keep it installed even when I have a full DAW open.
