Bouncing means taking audio from one track and placing it on another. The term,
sometimes called “bouncing down,” also describes the process of mixing several
tracks onto one or two.
Bus
A bus generally refers to any common signal pathway. In a mixer, a bus is usually a
wire that is or can be made common to the outputs of any or all channels in the
mixer. Examples of buses include the main stereo mix, sub-mixes, monitor buses and
aux sends.
C
Channel
In audio, a channel is an internal audio path maintained separately from other audio
paths of identical function. Mixer input strips are examples of channels, but an audio
snake also has channels.
Chase/Lock
Chase/Lock refers to a tape machine’s ability to read incoming timecode, locate its
tape to the position indicated by the timecode, and synchronize playback to the
incoming timecode.
Clip
In the analog world, clipping occurs when the input to a circuit exceeds the gain of the
circuit. The circuit passes the signal at its maximum value. All input values exceeding
the maximum value are “clipped.” The result is audio distortion. In digital audio,
clipping occurs when the input to an A/D exceeds the voltage represented by the
maximum number the A/D is capable of transmitting.
Crossfade
A crossfade is a gradual “dissolve” between two portions of audio; one segment of
audio fades out while the other fades in. When punching in on the XT, the audio on
tape is faded out while the new audio which is being recorded is faded in.
D
DAT
Digital Audio Tape. This term has come to mean specific digital audio tape recorders
that use cartridges smaller than those of a standard cassette, and which record two
tracks of digital audio (and sometimes timecode).
Digital I/O
Input and output connections where signals passed from one stage to another remain
in the digital domain. The XT has digital I/O connectors that carry digital data for all
eight tracks.
D/A or Digital-to-Analog Converter
The device that converts digital signals back into an analog format so that they can
be heard.
