bit depth The number of bits a digital recording or digital device uses. The number of
bits in each sample determines the theoretical maximum dynamic range of the audio
data, regardless of sample rate. Also known as bit resolution, word length, or bit rate.
bit rate See bit depth
bit resolution See bit depth
blue noise Highpass-filtered white noise, sounds like tape hiss.
boosting The act of raising an audio level.
bounce To process recorded or streamed MIDI and/or Audio Regions with any applied
effects, such as delay or compression, combining them into one audio file. In Logic, you
can choose between Realtime and Offline bouncing. Offline bouncing is faster, but
doesn’t allow you to apply live automation or record real time audio input.
Bounce button You can bounce the output of any Output Object to an audio file by
clicking the Object’s Bounce button. See also bounce.
bpm Abbreviation for beats per minute, a measure of the tempo of musical piece. As
an example: 120 bpm means that in one minute, there will be 120 musical beats
(quarter notes).
bus The term bus is used to describe a send/return routing scheme for audio channels.
In Logic, effects can be sent to/from Bus Objects for processing or submixing tasks.
Bus Object Audio Object in the Environment’s Audio layer. Usually used to route the
signal of an individual send bus to Output Objects. See also bus.
bypass To deactivate a plug-in. Bypassed plug-ins do not drain system resources. In
Logic you can bypass a plug-in by either clicking its Bypass button in the plug-In
window or by Option-clicking on the appropriate plug-in slot.
cable In Logic the term cable is used to describe the virtual cables that represents the
MIDI connection between two Environment Objects.
carrier In FM synthesis, the carrier is the equivalent of an analog synthesizer oscillator
that is producing a sine wave. The carrier frequency is modulated by the modulator.
Catch button The button in the Transport bar featuring the running man icon. Activate
this button (blue) to turn on automatic horizontal scrolling during playback. This
ensures that the current playback position is always visible.
Catch function A window function that makes the currently displayed song section
reflect the current song position. Also see Catch button.
