TempoScaleBands¶

streaming mode | Rhythm category

Inputs¶

bands (vector_real) - the audio power spectrum divided into bands

Outputs¶

scaledBands (vector_real) - the output bands after scaling

cumulativeBands (real) - cumulative sum of the output bands before scaling

Parameters¶

bandsGain (vector_real, default = [2, 3, 2, 1, 1.20000004768, 2, 3, 2.5]) :
gain for each bands

frameTime (real ∈ (0, ∞), default = 512) :
the frame rate in samples

Description¶

This algorithm computes features for tempo tracking to be used with the TempoTap algorithm. See standard_rhythmextractor_tempotap in examples folder.

An exception is thrown if less than 1 band is given. An exception is also thrown if the there are not an equal number of bands given as band-gains given.

Quality: outdated (the associated TempoTap algorithm is outdated, however it can be potentially used as an onset detection function for other tempo estimation algorithms although no evaluation has been done)
