Glossary 617
Control|24 Digidesign-dedicated controller for
Pro Tools systems. Includes 16 premium micro-
phone preamps, a control room monitoring sec-
tion, and a line submixer. Ideal front-end for
Pro Tools recording, mixing, and editing.
crossfade Function for fading out from one re-
gion as you fade in to another region. Crossfade
duration is user-selectable from within the Edit
window. As with fades, portions of audio for
which the crossfade function has been applied
are stored in the session’s Fade Files folder.
d24 Digidesign’s original 24-bit TDM core card,
needs a DSP Farm card to create a Pro Tools|24
TDM system.
D/A (digital-to-analog) Digital-to-analog con-
verters operate at various bit-rate resolutions
and sampling rates, converting digital audio sig-
nals to analog audio signals.
DAE (Digidesign Audio Engine) Digidesign’s real-
time operating system that provides the core
functionality of hard disk recording, digital sig-
nal processing, mix automation, and MIDI re-
quired by Pro Tools and other Digidesign prod-
ucts.
database Databasing is a convenient way of
storing, organizing, searching, and displaying
information. A database file is a collection of
records that hold data. In this guide, the term
“database” refers to a DigiBase database file.
Pro Tools creates and stores database files on lo-
cal volumes as needed.

Digidesign Audio Engine See DAE.
dither “Noise” added to an audio signal when
down-sampling bit rates. Designed to create a
smoother transition at lower amplitudes.
drop frame Refers to a variance of SMPTE/EBU
time code for NTSC color video (29.97 fps) that
omits two frames (frames “0” and “1”) every
minute except for every tenth minute.
DSP (Digital Signal Processing) In audio terms,
DSP refers to manipulation of digital audio—ev-
erything from reverberation to changes in level.
DSP Farm PCI card containing DSP chips, the
basic building blocks of a Pro Tools|24 TDM sys-
tem.
Edit cursor Flashing line that appears when you
click in a track in the Edit window.
edit decision list (EDL) List of edits, or events,
typically with each event’s respective source in
and out times, source reel number, and record in
and out times.
