Struct ZeroCrossingRateDesc

pub struct ZeroCrossingRateDesc { /* private fields */ }

Zero-crossing rate detection object.

Zero-crossing rate is mostly used to detect percussive sounds in an audio signal, as well as whether an audio signal contains speech or not.

It is a good metric to differentiate between songs with people speaking clearly, (e.g. slam) and instrumental songs.

The value range is between 0 and 1.

Implementations

pub fn do_(&mut self, chunk: &[f32])

Count the number of zero-crossings for the current chunk.

pub fn get_value(&mut self) -> Feature

Sum the number of zero-crossings witnessed and divide by the total number of samples.
