Glossary
L
Level Meters Adobe Audition’s Level Meters are found by default along the bottom of the
application window, and they are used to monitor the volume of incoming and outgoing
signals. The red clip indicator to the right of the meters will light up and remain lit when
levels exceed the maximum of 0 dB. Clicking the clipping indicator resets it. The top meter
represents the left channel, and the bottom meter represents the right.
Limiter A signal processor that limits input signals that exceed a specified threshold level.
Above the threshold, the output level remains constant even if the input increases in
volume.
Loop An audio file that contains tempo and pitch information, allowing it to match the
tempo and pitch of other loops in a multitrack session. You can repeat a loop-enabled clip
infinitely by simply dragging its bottom right corner.
M
Mastering The process of finalizing audio for a specific medium, such as the Web or audio
CD. Mastering consists of several processing phases, with equalization and compression
phases being the most essential. You can master audio files either individually or in groups.
(Collectively mastering groups of files is particularly important if the destination medium
is audio CD.)
MIDI Musical Instrument Digital Interface, a way of communicating performance infor-
mation from one piece of software or hardware to another. MIDI can simply relay musical
notes, or it can transmit detailed information about timing, synthesizer patches, and such.
Windows transmits MIDI information internally between applications; to transmit MIDI
information to and from your computer and external devices such as MIDI keyboards,
you must use a hardware MIDI interface (for example, the MIDI In port of a sound card).
MIDI Timecode (MTC) A method of sending timing information between MIDI-capable
devices. For example, you can convert SMPTE timecode to MTC to synchronize Adobe
Audition’s transport controls with a video or audio tape deck.
MIDI Trigger An Adobe Audition shortcut triggered by a MIDI event, such as Note On.
You can send MIDI events to any device capable of issuing a MIDI command, such as
MIDI keyboards and sequencers.
Millisecond (ms) One thousandth of a second. (There are 1000 milliseconds in a second.)
