Struct BPMDesc

Source

pub struct BPMDesc { /* private fields */ }

Expand description

Beats per minutes (BPM) detection object.

It indicates the (subjective) “speed” of a music piece. The higher the BPM, the “quicker” the song will feel.

It uses SpecFlux, a phase-deviation onset detection function to perform onset detection; it proved to be the best for finding out the BPM of a panel of songs I had, but it could very well be replaced by something better in the future.

Ranges from 0 (theoretically…) to 206 BPM. (Even though aubio apparently has trouble to identify tempo > 190 BPM - did not investigate too much)

Implementations§

Source §

pub fn get_value(&mut self) -> Feature

Compute score related to tempo. Right now, basically returns the song’s BPM.
