Struct StreamingStft 

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

Implementations

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

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

where FftPlanner<T>: FftPlannerTrait<T>,

pub fn push_samples(&mut self, samples: &[T]) -> Vec<SpectrumFrame<T>>

pub fn push_samples_into( &mut self, samples: &[T], output: &mut Vec<SpectrumFrame<T>>, ) -> usize

Push samples and write frames into a pre-allocated buffer. Returns the number of frames written.

pub fn push_samples_write( &mut self, samples: &[T], frame_pool: &mut [SpectrumFrame<T>], pool_index: &mut usize, ) -> usize

Push samples and write directly into pre-existing SpectrumFrame buffers. This is a zero-allocation method - frames must be pre-allocated with correct size. Returns the number of frames written.

Example

let mut frame_pool = vec![SpectrumFrame::new(config.freq_bins()); 16];
let mut frame_index = 0;

let frames_written = stft.push_samples_write(chunk, &mut frame_pool, &mut frame_index);
// Process frames 0..frames_written

pub fn flush(&mut self) -> Vec<SpectrumFrame<T>>

pub fn reset(&mut self)

pub fn buffered_samples(&self) -> usize
