What It Provides ​

The aubio bindings are exposed as a family of canonical submodules for audio vectors, spectral processing, temporal analysis, audio file IO, synthesis, and utility helpers.

API Summary ​

  • Canonical submodules: aubio/vec, aubio/spectral, aubio/temporal, aubio/io, aubio/synth, and aubio/utils.
  • aubio/vec provides FVec, CVec, FMat, LVec, vector math/statistics, thresholds, peak picking, autocorrelation, mixdown, and normalization helpers.
  • aubio/spectral provides FFT, DCT, PVoc, Filterbank, MFCC, SpecDesc, SpectralWhitening, and TSS.
  • aubio/temporal provides Pitch, Onset, Tempo, Notes, Resampler, Filter, FilterBiquad, FilterAWeighting, and FilterCWeighting.
  • aubio/io provides Source and Sink.
  • aubio/synth provides Sampler and Wavetable.
  • aubio/utils provides Parameter, Scale, Hist, log hooks, audio-input-into-fvec, window, frequency/MIDI/bin/mel conversions, unwrap2pi, and cleanup.

Examples ​

fennel
(local aubio-vec (require :aubio/vec))
(local aubio-temporal (require :aubio/temporal))

(local samples (aubio-vec.FVec 1024))
(local pitch (aubio-temporal.Pitch :yin 1024 512 48000))
;; Fill samples from audio input or a file source before running temporal analysis.

Errors and Platform Notes ​

Constructors and processing methods follow aubio's native size, method-name, sample-rate, and buffer constraints. Pair matching buffer and hop sizes across vector, spectral, temporal, and IO modules.
