Struct BatchStft 

pub struct BatchStft<T: Float + FftNum> { /* private fields */ }

Implementations

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

pub fn new(config: StftConfig<T>) -> Self

pub fn process(&self, signal: &[T]) -> Spectrum<T>

pub fn process_padded(&self, signal: &[T], pad_mode: PadMode) -> Spectrum<T>

pub fn process_into(&self, signal: &[T], spectrum: &mut Spectrum<T>) -> bool

Process signal and write into a pre-allocated Spectrum. The spectrum must have the correct dimensions (num_frames x freq_bins). Returns true if successful, false if dimensions don’t match.

pub fn process_padded_into( &self, signal: &[T], pad_mode: PadMode, spectrum: &mut Spectrum<T>, ) -> bool

Process signal with padding and write into a pre-allocated Spectrum.

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

Process multiple channels independently. Returns one Spectrum per channel.

Arguments

• channels - Slice of audio channels, each as a separate Vec

Panics

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

Example

use stft_rs::prelude::*;

let config = StftConfigF32::default_4096();
let stft = BatchStftF32::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);
assert_eq!(spectra.len(), 2); // One spectrum per channel

pub fn process_interleaved( &self, data: &[T], num_channels: usize, ) -> Vec<Spectrum<T>>

Process interleaved multi-channel audio. Converts interleaved format (e.g., [L,R,L,R,L,R,...] for stereo) into separate Spectrum for each channel.

Arguments

• data - Interleaved audio data
• num_channels - Number of channels

Panics

Panics if num_channels is 0 or if data.len() is not divisible by num_channels.

Example

use stft_rs::prelude::*;

let config = StftConfigF32::default_4096();
let stft = BatchStftF32::new(config);

// Stereo interleaved: L,R,L,R,L,R,...
let interleaved = vec![0.0; 88200]; // 2 channels * 44100 samples

let spectra = stft.process_interleaved(&interleaved, 2);
assert_eq!(spectra.len(), 2); // One spectrum per channel
