Music Technology Glossary

A device that converts continuous analog audio signals into discrete digital samples for computer processing and storage.

The magnitude of an audio signal, corresponding to its loudness. Measured in decibels (dB) in audio engineering contexts.

The number of audio samples processed in a single block by a computer's audio system. Larger buffers increase latency but reduce CPU load; smaller buffers decrease latency but increase processing demands.

A signal path in a mixer or DAW that combines multiple audio channels for collective processing or routing, such as a submix bus or effects send bus.

Distortion that occurs when an audio signal exceeds the maximum level a system can handle, causing the waveform peaks to be flattened or 'clipped.'

A device that converts discrete digital audio data back into a continuous analog signal for playback through speakers or headphones.

Software application used for recording, editing, mixing, and producing audio, serving as the central platform for modern music production.

A logarithmic unit used to express the ratio between two values, commonly used to measure sound pressure level, signal level, and gain in audio systems.

An audio effect that records a signal and plays it back after a specified time interval, creating echoes. Parameters include delay time, feedback, and wet/dry mix.

An alteration of the original audio waveform shape, which can be undesirable (clipping) or intentionally applied as a creative effect (overdrive, fuzz, saturation).

The number of complete oscillation cycles a sound wave completes per second, measured in Hertz (Hz). Determines the perceived pitch of a sound.

The increase or decrease in signal level, measured in decibels. Applied at various stages in the audio chain including preamps, EQ bands, and output faders.

A frequency component of a sound that is an integer multiple of the fundamental frequency. The pattern and amplitude of harmonics determine a sound's timbre.

The difference between the nominal operating level of a signal and the maximum level a system can handle before clipping. Adequate headroom prevents unwanted distortion.

A recording of how an acoustic space or device responds to a brief, broadband sound (impulse). Used in convolution reverb and cabinet simulation to recreate real-world acoustic characteristics.

A filter that allows frequencies below a cutoff point to pass through while attenuating frequencies above it. Fundamental to subtractive synthesis and mix EQ.

The final stage of audio production where a completed mix is optimized for distribution through processes including EQ, compression, limiting, stereo enhancement, and loudness normalization.

The process of combining multiple audio tracks into a final stereo or multichannel output by adjusting levels, panning, EQ, dynamics, and effects for each track.

An electronic circuit or digital algorithm that generates a periodic waveform (sine, sawtooth, square, triangle) serving as the fundamental sound source in a synthesizer.

The distribution of an audio signal between left and right channels in a stereo field, or across multiple channels in surround sound, to create spatial positioning.

48-volt DC power supplied through balanced microphone cables (typically XLR) to power condenser microphones and active direct injection boxes.

A software component that adds functionality to a DAW, typically in VST, AU, or AAX format. Plug-ins include virtual instruments, effects processors, and utility tools.

A circuit that amplifies a low-level signal (such as from a microphone) to a standard operating level suitable for further processing or recording.

A single measured value of an audio waveform at a specific point in time during digital recording, or a recorded segment of audio used as a sound source in composition.

The shape of an audio signal as it varies over time. Common synthesizer waveforms include sine, sawtooth, square, and triangle, each with distinct harmonic content.
