Today a tip from the old school days! When tape machines were the only recording medium in studios, there were some sonic compromises to go along with the nice saturation and warmth, namely tape hiss. When recording was limited to 4 or 8 tracks, things would have to be recorded, mixed, and then all recorded down to a single track to free up the rest of the tracks. This process is known as bouncing, and it exists in the modern world of computer recording as well. Except now instead of bouncing down to a single tape track, you're bouncing to a single wave file. Now with tape, the issue was that as you re-recorded things, the hiss would get recorded as well and the more times you bounced something, the more hiss that would build up.
