Struct PVoc 

pub struct PVoc { /* private fields */ }

Phase vocoder object

Implementations

impl PVoc

pub fn new(win_size: usize, hop_size: usize) -> Result<Self>

Create phase vocoder object

• win_size Size of analysis buffer (and length the FFT transform)
• hop_size Step size between two consecutive analysis

pub fn with_window(self, window_type: WindowType) -> Result<Self>

Select window type

pub fn get_hop(&self) -> usize

Get hop size

pub fn get_win(&self) -> usize

Get window size

pub fn do_<'i, 'o, I, O>(&mut self, input: I, fftgrain: O) -> Status

where I: Into<FVec<'i>>, O: Into<CVecMut<'o>>,

Compute spectral frame

This function accepts an input vector of size hop_size. The analysis buffer is rotated and filled with the new data. After windowing of this signal window, the Fourier transform is computed and returned in fftgrain as two vectors, magnitude and phase.

• input New input signal (hop_size long)
• fftgrain Output spectral frame (win_size long)

pub fn rdo<'i, 'o, I, O>(&mut self, fftgrain: I, output: O) -> Status

where I: Into<CVec<'i>>, O: Into<FVecMut<'o>>,

Compute signal from spectral frame

This function takes an input spectral frame fftgrain of size win_size and computes its inverse Fourier transform. Overlap-add synthesis is then computed using the previously synthetised frames, and the output stored in out.

• fftgrain Input spectral frame (win_size long)
• output Output signal (hop_size long)

pub fn set_window(&mut self, window_type: WindowType) -> Status

Set window type

impl Drop for PVoc

fn drop(&mut self)

Executes the destructor for this type.
