Implementations

impl Stft

pub fn new(config: StftConfig) -> Self

pub fn analyze(&self, signal: &[f32]) -> Vec<Spectrum>

Analyze a signal into a sequence of Spectrum frames.

pub fn synthesize(&self, frames: &[Spectrum]) -> Vec<f32>

Synthesize a signal from STFT frames using overlap-add (OLA).

pub fn num_frames(&self, signal_len: usize) -> usize

Number of frames for a signal of given length.

pub fn frame_time(&self, idx: usize, sample_rate: f32) -> f32

Time in seconds of the center of frame idx.
