Implementations§

Source §

impl<T: Float + FftNum + FromPrimitive + Debug> BatchIstft<T>

Source

pub fn new(config: StftConfig<T>) -> Self
where FftPlanner<T>: FftPlannerTrait<T>,

Source

pub fn process(&self, spectrum: &Spectrum<T>) -> Vec<T>

Source

pub fn process_into(&self, spectrum: &Spectrum<T>, output: &mut Vec<T>)

Process spectrum and write into a pre-allocated output buffer. The output buffer will be resized if needed.

Source

pub fn process_multichannel(&self, spectra: &[Spectrum<T>]) -> Vec<Vec<T>>

Reconstruct multiple channels from their spectra. Returns one Vec per channel.

§Arguments

spectra - Slice of Spectrum, one per channel

§Panics

Panics if spectra is empty.

§Example

use stft_rs::prelude::*;

let config = StftConfigF32::default_4096();
let stft = BatchStftF32::new(config.clone());
let istft = BatchIstftF32::new(config);

let left = vec![0.0; 44100];
let right = vec![0.0; 44100];
let channels = vec![left, right];

let spectra = stft.process_multichannel(&channels);
let reconstructed = istft.process_multichannel(&spectra);

assert_eq!(reconstructed.len(), 2); // One channel per spectrum

Source

pub fn process_multichannel_interleaved( &self, spectra: &[Spectrum<T>], ) -> Vec<T>

Reconstruct multiple channels and interleave them into a single buffer. Converts separate channels back to interleaved format (e.g., [L,R,L,R,L,R,...] for stereo).

§Arguments

spectra - Slice of Spectrum, one per channel

§Panics

Panics if spectra is empty or if channels have different lengths.

§Example

use stft_rs::prelude::*;

let config = StftConfigF32::default_4096();
let stft = BatchStftF32::new(config.clone());
let istft = BatchIstftF32::new(config);

// Process interleaved stereo
let interleaved = vec![0.0; 88200]; // 2 channels * 44100 samples
let spectra = stft.process_interleaved(&interleaved, 2);

// Reconstruct back to interleaved
let output = istft.process_multichannel_interleaved(&spectra);
// Output length may differ slightly due to padding/framing
assert_eq!(output.len() / 2, 44032); // samples per channel after reconstruction
