Audio Token
A discrete identifier produced by an audio codec or tokenizer for a short segment or feature of an audio signal, sometimes across several codebooks.
Why it matters
Discrete audio representations let sequence models process, predict, store, or generate sound using token-oriented architectures.
In practice
Version the codec with the model, preserve sample-rate and codebook metadata, measure reconstruction quality, and distinguish semantic audio tokens from waveform-compression tokens.
Common confusion
An audio token is not a fixed duration, phoneme, or word. Its meaning and time span depend on the tokenizer and codebook design.
