Both Bounce to Disk and recording to tracks operate on the current Timeline or Edit selection, if one exists. This makes it easy to turn multitrack selections into mono, stereo, or multichannel loops. Submixes, stems, and other specialized types of mixes can also be recorded (or “printed”) to disk using either method, or played out to another recording, transfer, or archiving medium.
Printing effects to disk is the technique of permanently adding real-time effects, such as EQ or reverb, to an audio track by bussing and recording it to new tracks with the effects added. The original audio is preserved, so you can return to the source track at any time. This can be useful when you have a limited number of tracks or effects devices.
