Struct MelFilterbank 

pub struct MelFilterbank {
    pub n_filters: usize,
    pub fft_size: usize,
    pub sample_rate: f32,
    /* private fields */
}

Mel-scale filterbank for perceptual frequency analysis.

Fields

n_filters: usize

Number of Mel filters.

fft_size: usize

FFT size.

sample_rate: f32

Sample rate.

Implementations

impl MelFilterbank

pub fn new(n_filters: usize, fft_size: usize, sample_rate: f32) -> Self

Create a Mel filterbank.

pub fn apply(&self, spectrum: &[f32]) -> Vec<f32>

Apply the filterbank to a power spectrum. Returns n_filters values.

pub fn apply_spectrum(&self, spectrum: &Spectrum) -> Vec<f32>

Apply to a Spectrum struct.
