USING ADOBE AUDITION 22 Importing, recording, and playing audio Bit Depth Determines the amplitude range of the session, including recordings and files created with the Multitrack > Mixdown To New File command. (See "Understanding bit depth" on page 6.) Important: Choose a bit depth carefully, because it cannot be changed after you create a session. Ideally, you should work at the 32-bit level with CoreAudio and ASIO sound cards, and the 16-bit level with MME cards. If your system performs slowly, try a lower bit depth. Master Determines whether tracks are mixed down to a mono, stereo, or 5.1 Master track. (See "Routing audio to buses, sends, and the Master track" on page 112.)
