Sample Rate
In digital audio, the sample rate is the number of individual audio samples captured per second. It determines the highest reproducible frequency and influences file size and perceived fidelity.

Automation (Production)
Automation in audio production is the technique of recording and recalling changes to mix parameters such as volume, pan, and effects over time, enabling precise, repeatable adjustments throughout a track.
Limiter (audio device)
A limiter is a type of dynamic range processor that prevents an audio signal from exceeding a set threshold, ensuring levels stay within a desired range. It is commonly used in recording, mixing, broadcasting, and live sound to protect equipment and maintain consistent loudness.
Noise Gate
A noise gate is an audio processing tool that attenuates or silences signals that fall below a set amplitude threshold, helping to remove unwanted background noise and improve clarity in recordings and live sound.
Loudness Units (LUFS)
Loudness Units relative to Full Scale (LUFS) is a standardized measurement of perceived audio loudness. It is used in broadcasting, streaming, and mastering to ensure consistent playback levels across different platforms.
Waveform
A waveform is a visual representation of how an audio signal varies over time, showing its amplitude, frequency, and shape, which together determine the sound’s timbre and character.
Compression (Audio)
Audio compression is a signal‑processing technique that reduces the dynamic range of sound by attenuating louder passages and/or amplifying quieter ones. It is a fundamental tool in recording, mixing, mastering, broadcast, and live‑sound applications, shaping both the technical and artistic aspects of modern audio.
Mastering (Audio)
Mastering is the final stage of audio production where a stereo mix is refined for consistent playback across formats and devices. It involves equalisation, dynamics processing, sequencing, and preparation for distribution.
Spatial Audio
Spatial audio is a set of techniques that recreate a three‑dimensional sound field, allowing listeners to perceive audio sources as coming from specific directions and distances.
Overdubbing (audio recording technique)
Overdubbing is a studio recording process where additional sounds are recorded on top of an existing track. It enables musicians to layer multiple performances, create harmonies, and correct mistakes without re‑recording the entire piece.
