Struct LogMel 

pub struct LogMel { /* private fields */ }

Whisper log-mel extractor. Owns the FFT plan, window, and filterbank; build once, reuse per utterance.

Implementations

impl LogMel

pub fn new() -> Self

pub fn compute(&self, samples: &[f32]) -> (Vec<f32>, usize)

Computes the log-mel spectrogram of samples (16 kHz mono). Returns row-major [N_MELS, n_frames] with n_frames = samples.len() / HOP_LENGTH (centered STFT, last frame dropped — the Whisper convention).

Trait Implementations

impl Default for LogMel

fn default() -> Self

Returns the “default value” for a type.
