Struct Stft 

pub struct Stft<S: SpectralStage> { /* private fields */ }

STFT processor implementing the DspStage contract.

Accepts arbitrary input block sizes, buffers in an input FIFO, processes one hop at a time with a SLIDING analysis frame (each hop consumes hop_len new samples and re-uses the previous half — the overlap in “weighted overlap-add”), and emits exactly as many output samples as arrived. sqrt-Hann is applied on analysis and synthesis; with the periodic window at 50% overlap the squared windows sum to exactly 1 (COLA), so an identity spectral stage reconstructs the input delayed by one window length.

Implementations

impl<S: SpectralStage> Stft<S>

pub fn new(stage: S, sample_rate: u32) -> Self

Create a new STFT processor: window 20 ms at sample_rate, hop 10 ms (50% overlap). A sample-rate change re-initializes (flushes).

Trait Implementations

impl<S: SpectralStage> DspStage for Stft<S>

fn name(&self) -> &'static str

Short stable name, shown in metrics snapshots.

fn process(&mut self, bus: &mut AudioBus<'_>)

Process one block in place.

fn latency_samples(&self) -> usize

Group delay this stage introduces, in samples at the bus rate (lookahead, filter delay, block buffering). Default 0.
