Beat tracking is a music information retrieval technique that determines the temporal positions of perceptual beats in musical audio. The method operates by: (1) extracting an onset function from the audio signal, (2) computing a beat-synchronous representation or autocorrelation of the onset sequence, (3) estimating the tempo from periodicity peaks, and (4) aligning beat positions to the estimated tempo using dynamic programming or Viterbi decoding. The output is a sequence of beat times synchronized to the music's underlying pulse. Persistence mechanism: implemented in beat-detection algorithms within digital audio workstations, rhythm analysis software, and music information retrieval toolkits; taught as a core technique in MIR curricula.

Definition
Why it is in scope

Removal test: beat-tracking operates by first detecting onsets and then analysing their temporal regularity to find beat positions. Remove onset-detection and the technique loses its primary input — the onset sequence — and has no mechanism to produce it.

Beat tracking is designed and maintained for the sake of music information retrieval: identifying perceptual beat positions is a foundational MIR task used in audio indexing, recommendation, and transcription. Its designed purpose is to further MIR's operation.

Beat-tracking algorithms need signal processing for their core operations — FFT, autocorrelation, spectral analysis. Remove signal processing and beat-tracking algorithms collapse. The removal test passes: beat-tracking does not operate without signal processing infrastructure.

Beat-tracking IS a specific kind of music information retrieval task — a competent speaker would call beat-tracking 'an MIR task.' Files against the nearest kind: beat-tracking is a sub-task within the MIR field.

Rhythm as a human concept predates beat-tracking as a computational method. Beat-tracking is the automated extraction of rhythmic structure from audio — it derives from the prior existence of rhythm as both a natural phenomenon mapped by humans and a concept studied in music theory. Which-came-first test passes.
