A tool used to play a region or event in isolation.
Short for Sony/Philips Digital Interface. A standard transmission format for professional stereo digital audio signals. The format is similar to AES/EBU, but uses 75 ohm coaxial or optical connectors and cabling. Depending on the type of devices involved, AES/EBU and S/P-DIF coaxial interfaces can communicate directly. Most digital audio interfaces available today will feature S/P-DIF connectors.
Often the channels of multichannel audio files (stereo or surround) are interleaved, so that edits to one channel affect the others equally. Logic Pro for Mac allows you to separate these files into split channel audio files, so that you can edit each channel independently. See also interleaved audio file.
Abbreviation for Song Position Pointer. A MIDI Clock timing pulse sub-message that indicates the current “song” (project) position. It is accurate to bars (and beats for some devices), but is not as accurate as MIDI Time Code (MTC), which is preferred when you have a choice when synchronizing Logic Pro for Mac. See also MIDI Clock and MTC.
Determines the appearance of notation on a musical staff. You can define note sizing and spacing, number of staff lines, fonts, and more for each staff style.
The standard file format for exchanging songs between different sequencers or MIDI file players. Standard MIDI files are not specific to a particular sequencer program, type of computer, or device.

When you create a summing stack, the outputs from the subtracks are routed to a bus, the destination aux of which is assigned to the main track. When the main track is selected, you can mute, solo, and adjust volume and send levels for the summing stack, and add and edit plug-ins, affecting the sound of all the subtracks in the summing stack. See also track stack.
Describes playback systems that make use of multiple speakers. The most common surround format is 5.1 channels (front left, front center, front right, left surround, right surround, and an LFE, or subwoofer, channel), typically used in home theater systems and in cinemas. Logic Pro for Mac supports all common surround formats, and provides surround recording, plug-in, and mixing facilities.
Replaces the standard Pan/Balance knob of channel strips for surround projects. The Surround Panner control allows you to control the relative positioning of the channel signal between the available speakers (in the chosen project surround format).

An editor used to define a set of conditions and operations for selecting and manipulating specific MIDI events.
A point in an audio recording where the signal becomes louder over a short time span. It is a short burst of amplitude, normally at the onset of a sound. Because this behavior is typical for rhythmic or percussive parts of music, such as a drumstick hitting a snare drum, transients can be used to indicate where beats occur in an audio signal.
A process in which audio files are analyzed for transients the first time you enable a track for flex editing. See also flex editing.
A marker that denotes a significant point or peak in an audio file. See also transient.

Abbreviation for Volume Unit meter. An analog meter used to monitor audio levels, typically with a circular face and a moving needle.
The primary audio file format used by Windows-compatible computers. In Logic Pro for Mac, all recorded and bounced WAVE files are in Broadcast Wave format, which includes high-resolution timestamp information that stores positional information. This makes it easy to align these files in other audio and video apps.
A visual representation of an audio signal. Waveform graphics run from left to right, and are centered on a horizontal line. Louder portions of the waveform (amplitude peaks) are indicated as taller peaks or curves in the waveform.
Refers to the ratio of a signal that effects have been added to (wet), and the original, unprocessed signal (dry).
A type of noise in which all frequencies in a given frequency band sound simultaneously, at the same intensity. Its name is analogous to white light, which consists of a mixture of all optical wavelengths (all rainbow colors). Sonically, white noise falls between the sound of the consonant F and breaking waves (surf). Synthesis of wind and seashore noises, or electronic snare drum sounds, typically makes use of white noise.
The clock signal required by digital audio interfaces to ensure that the sampling rates of connected devices run synchronously. When two devices are connected via a standard digital audio interface (such as S/P-DIF or ADAT optical), Word Clock is transmitted via the audio circuit. If you want more than two digital audio devices to communicate with each other, you need to use separate Word Clock ports for synchronization, in most cases.
