Struct Stft

Source

pub struct Stft { /* private fields */ }

Expand description

libDF’s frame-by-frame STFT (analysis memory of one hop, synthesis overlap-add).

Implementations§

Source §

impl Stft

Source

pub fn new(fft_size: usize, hop: usize) -> Stft

Source

pub fn analysis(&self, x: &[f32]) -> Vec<Vec<Complex32>>

Spectra of x (len / hop frames; frame t covers samples (t−1)·hop … (t+1)·hop).

Source

pub fn synthesis(&self, spec: &mut [Vec<Complex32>]) -> Vec<f32>

Overlap-add synthesis: frames × hop samples.
