Autopunch function A function that allows you to start and stop recording at predefined
positions. Autopunch mode is most commonly used to re-record a section of an otherwise
successful recording. The advantage is that you can concentrate on playing, rather than
the mechanics of starting and stopping recording. See also Autopunch button.
aux channel strip A channel strip found in the Mixer that can be used as a send/return
(bus) and subgroup control.
backup A saved version of the current project. Backups for the current alternative are
listed in descending order from newest to oldest in the Project > Revert to submenu,
Balance control A rotary knob above the Volume fader of stereo channel strips. It controls
the relative level of the left and right signals at their outputs.
band rejection filter A filter that cuts the frequency band centered around the cutoff
frequency, while allowing the frequencies that lie further away on either side to pass.
Frequencies close to the cutoff frequency are attenuated, while the lows and highs remain
unchanged. See also filter.
bandpass filter A filter that allows only the frequency band centered around the cutoff
frequency to pass, while frequencies that lie further away are cut. Frequencies close to the
cutoff frequency are emphasized, while the lows and highs are attenuated, resulting in a
sound containing mostly mid-range frequencies. See also filter.
bar In musical notation, a measure that contains a specified number of beats, defined by
the project time signature. See also time signature.
bass (1) A musical instrument. (2) Low-frequency sounds or components within a sound.
See also frequency.
beat A musical time interval, commonly a quarter note, that marks the basic pulse of a
piece of music.
Beat Mapping track A Global track used to analyze audio or MIDI regions, and create
tempo events based on note or transient events in these regions, allowing you to more
easily synchronize recordings made without a metronome click with other material in a
project.
binaural hearing Refers to the way human beings process audio positioning information,
allowing the direction of a signal source to be recognized (in front, behind, above, below,
and to the left or right of the listening position).
binaural panning A process that emulates binaural hearing.
bit depth The number of bits used by a digital recording or digital device. The number
of bits in each sample determines the (theoretical) maximum dynamic range of the audio
data, regardless of sample rate.
bit rate When talking about MP3 files, refers to the transfer bit rate at which the files are
encoded. Conversationally, the term is more often used to describe the relative quality of
the file, with lower bit rates resulting in less defined audio.
bit resolution An alternative term for bit depth. See bit depth and sample rate.
blue noise Refers to highpass-filtered white noise, which sounds like tape hiss.
boosting The act of raising an audio level. See also cutting.
