There’s a lot of jargon in the audio world. So we’ve put together this glossary of music production terms for composers and producers to reference.
Most of these are common words and phrases used in music and audio production. Others are specific instruments, brands, or terms we frequently mention here on Sonic Atlas. When relevant, we’ll link to other resources that expand on these topics.
We frequently update this glossary. So be sure to check back if you find another word you’re not familiar with.

Tape Emulation — A common type of plugin designed to emulate the sound and characteristics of magnetic tape machine. They can be used to create a warm or vintage sound.
Tempo — The speed of a piece of music, usually measured in beats per minute (BPM).
Threshold — The level at which a compressor starts to reduce the gain of an audio signal.
Timbre — The quality of a sound that distinguishes it from other sounds. Timbre is often affected by the frequency spectrum, the envelope, and the harmonics of a sound.
Tone — Can describe a single pitch or note. Tone can also describe the overall quality and timbre of a sound.
Track — An individual audio or MIDI channel in a DAW. Can also describe a finished product for listening.
Tracker — A type of music sequencer where notes and other information are represented on a vertical grid. Trackers were widely used to write music for retro video game consoles, and are still popular among chiptune enthusiasts.
Transport — The controls used to play, stop, rewind, and fast forward an audio or video file.
Transpose — The process of changing the pitch of an audio signal. Transpose is often used to change the key of a song or to create new harmonies.
Tremolo — A type of modulation effect that creates a rhythmic variation in the volume of an audio signal. Tremolos are often used to create a sense of movement or excitement in music.
Triangle Wave — A basic waveform shape produced by most synthesizers. As the name suggests, it has a triangular shape.
Trim — The process of adjusting the level of an audio signal. Trim is often used to balance the levels of different tracks in a mix.
Truncate — The process of cutting off the end of an audio signal. Truncate is often used to create a sharp or abrupt sound.
Tube — A type of electronic component often found in vintage audio equipment. They amplify mid-to-low frequencies and add additional warmth to a signal.
Tune — The pitch of an instrument. Most electronic and virtual instruments offer controls to adjust their tuning.
Tweeter — A loudspeaker designed to produce treble frequencies and other high-frequency sounds.
Unison — A feature found on synthesizers that layers multiple oscillators on top of each other. Usually, each oscillator is slightly detuned to create a thicker sound.
USB — A type of connection used to connect hardware devices to computers. Most modern audio interfaces, MIDI controllers, and other keyboards use USB.
VCA (Voltage-Controlled Amplifier) — An amplifier whose gain is controlled by a voltage signal. VCAs are often used in synthesizers to control the volume of an audio signal.
VCF (Voltage-Controlled Filter) — A filter whose cutoff frequency is controlled by a voltage signal. VCFs are often used in synthesizers to shape the sound of an audio signal.
VCO (Voltage-Controlled Oscillator) — An oscillator whose frequency is controlled by a voltage signal. VCOs are often used in synthesizers to generate the basic waveforms that make up an audio signal.
Velocity — The force with which a key is pressed on a MIDI keyboard. Velocity is often used to control the volume or timbre of a synthesizer or other virtual instruments.
Vibrato — The wavy, tremolo effect created by rapidly shifting a pitch up and down. Singers and acoustic instruments can do this naturally through their performance. Synthesizers often accomplish vibrato through an LFO.
Vinyl — A vintage physical audio format. Vinyl discs are created by inscribing information on the disc, which is played back using a needle and turntable.
Vinyl Distortion — A type of distortion that is created by the inherent imperfections of vinyl records.
Virtual Instrument — A software synthesizer or sampler that can be used to create or play back audio.
Vocoder — A device that combines the sound of a voice with the sound of a synthesizer to create electronic vocal effects.
Volume — The loudness of an audio signal, usually measured in decibels (dB).
Vox — Short for “voice” or “vocals”.
VST — A type of software plugin for music and audio production. They expand the capabilities of a DAW to provide new effects or virtual instruments.
WAV — A lossless audio file format. WAV files are often used to store high-quality audio recordings, and are a default output format for most DAWs and recording gear.

Wavetable — A collection of samples that can be scanned through a wavetable synthesizer.
Wavetable Synthesis — A type of synthesis that creates sound by combining and morphing samples from a wavetable.
Wet — A term used to describe the amount of reverb, delay, or other effect applied to an audio signal. The more wet, the more echo-y or saturated it’ll sound.
White Noise — A type of noise that plays sound equally across the entire frequency spectrum. It’s a sound that many synthesizers can produce.
Wind Controller or Wind Synth — An electronic instrument or MIDI controller with an air sensor. Most of them are designed for woodwind players and feature a key layout similar to a saxophone or clarinet.
