Gain

Gain controls signal level at the input or processing stage of the signal path.

Level relevance: introduced at Nat 3; tagged for every later level where the same concept remains useful.

Explanation

Gain refers to the level of a signal as it enters or passes through a stage in the signal path. During recording, input gain is adjusted so the source is captured clearly without clipping. In production, gain staging helps keep levels healthy throughout the project. Good gain control leads to cleaner recordings and more predictable mixing.

Clipping

Clipping happens when a signal is too loud and the peaks are cut off, causing distortion.

Normalisation

Normalisation raises or lowers a file’s level so its highest peak reaches a chosen target.
