ADOBE AUDITION 1.5
User Guide
Bit Part of the numbering system used in digital data. Bits are combined in groups to form
digital words, which represent the changing amplitude values of an analog signal. Bit
resolution describes the number of bits used in each word, determining the number of
possible amplitude values. Therefore, higher bit resolutions produce higher dynamic
range.
Bit resolution (or bit depth) The number of bits used to represent audio amplitude.
8-bit resolution provides a maximum of 256 unique amplitude levels, producing a 48 dB
dynamic range; 16-bit resolution provides 65,536 unique amplitude levels, producing a
96 dB dynamic range. Compact disc players have 16-bit resolution, but some sound cards
support resolutions higher than 16-bit. Adobe Audition supports up to 32-bit resolution.
For the best audio quality, remain at the 32-bit level while transforming audio in Adobe
Audition, and then convert to a lower resolution for output.
Brown noise Brown noise has a spectral frequency of 1/f^2, so it emphasizes low-
frequency components, resulting in thunder- and waterfall-like sounds. Brown noise
follows a Brownian motion curve, in which each sample in a waveform contains a mixture
of predefined and random frequency components.
Bus In hardware mixers, a channel that lets you combine several other channels and
output them together. In Adobe Audition’s Multitrack View, you can similarly use software
buses to combine several tracks.
Burn To write to a CD-R or CD-RW disc.
C
CD-R A recordable compact disc that you can write to only once. These discs typically hold
650 MB of data, which equals 74 minutes of stereo audio. CD-R sometimes refers to the
computer drives that burn CD-R discs.
CD-RW A rewritable compact disc. These discs typically hold 650 MB of data, which
equals 74 minutes of stereo audio. Unlike a CD-R, however, a CD-RW disc can be erased
and written to again.
Chorus A delay effect that simulates several voices by adding multiple short delays with a
medium amount of depth and a small amount of feedback.
Click track An audio track comprised of clicks that occur on the beat, like a metronome.
Click tracks are often used at the beginning of a session to provide timing information for
musicians and then removed from the session before mixing down.
