What’s Recorded on an Audio CD
It’s important to understand that an audio CD contains just that: audio. None of your
project settings are themselves written to an audio CD, only the audio that those
settings produce. It’s therefore critical that your final mix sound
exactly
as you want it
to—with all of the desired tracks, effects, live elements and so on—since that’s what the
audio CD will contain.
An audio CD can hold up to about 74 minutes worth of audio.
What is the Mastering Room?
An audio CD contains just two tracks of audio: a left and a right track. Your project must
therefore be mixed down to just two V-Tracks that can be burned onto a CD. On the
VS-2000, these two V-Tracks are called your “mastering tracks.” The Mastering Room is
where you create mastering tracks.
The Mastering Room has two operating modes. When it’s set to:
•
Record
—You can listen to the signals from all of your input, track, Aux master and
FX return channels as parts of the mix you record onto your mastering tracks.
•
Play
—You can play back your recorded mastering tracks. Input, track, Aux master
and FX return channel signals are silenced since their audio can now be heard in
the final mix recorded on the mastering tracks.
About Mastering Tracks
The mastering tracks that contain your final mix are always a pair of V-Tracks. To record
on these tracks—and to hear them back—you must be in the Mastering Room.
You can select any pair of same-numbered V-Tracks from mastering tracks. We’ll
describe how to select the desired V-Tracks on Page 360.
CD Disk Images
All commercially produced audio CDs conform to a set of standards called the “Red
Book” standards. The VS-2000 produces Red Book audio CDs.
Before the VS-2000 can burn audio onto a CD, it converts the audio into a Red Book-
compliant form of data called a “disk image file,” and stores the file on your internal
hard drive. It’s this stereo file that actually gets written onto the CD. A disk image file
can be as large as 700MB depending on how much audio you’re packing onto a CD.
The disk image file can be stored only on the VS-2000’s internal hard drive.
The VS-2000 can use any free space on your hard drive for creating a CD disk image—
the free space doesn’t have to be in the currently selected drive partition.
