@audio/beat-detect

import detect from '@audio/beat-detect'

Full pipeline: spectral flux onsets → comb-filter tempo → phase-aligned beat grid. Shares a single STFT pass across onset and tempo stages, so it costs only marginally more than either alone.

import detect from '@audio/beat-detect'
let { bpm, confidence, beats, onsets } = detect(samples, { fs: 44100 })

Returns { bpm, confidence, beats: Float64Array, onsets: Float64Array }.

Use when: Quick one-call solution — good enough for most applications.
Not for: Tempo changes or rubato — the grid is uniform. Use beatTrack for adaptive tracking.

Part of @audio/beat — the beat family umbrella. This README is generated from the umbrella docs.
