Struct SpectralDelay 

pub struct SpectralDelay<T: Transcendental, const BUF_SIZE: usize, const MAX_DELAY: usize> { /* private fields */ }

Spectral delay effect — applies different delay times to different frequency bins.

Stores a circular buffer of past FFT frames. Each bin’s output is a mix of the current bin and a delayed version with optional feedback.

Type parameters

• T — sample type (f32 or f64)
• BUF_SIZE — processing block size in samples
• MAX_DELAY — maximum delay in FFT frames

Implementations

impl<T: Transcendental, const BUF_SIZE: usize, const MAX_DELAY: usize> SpectralDelay<T, BUF_SIZE, MAX_DELAY>

pub fn new() -> Self

Create a new spectral delay.

Panics

Panics if MAX_DELAY is 0.

pub fn set_mix(&mut self, mix: f32)

Set wet/dry mix (0.0 = dry, 1.0 = wet).

pub fn set_feedback(&mut self, feedback: f32)

Set feedback amount (0.0 = no feedback, 0.99 = near infinite).

pub fn fft_size(&self) -> usize

Returns the FFT size.

pub fn process(&mut self, input: &[T], output: &mut [T])

Process one block of samples.

Combines the current spectrum with a delayed spectrum bin-by-bin. Lower-frequency bins can have longer delays than higher ones, creating unique spatial effects.

fn process( &mut self, input: Option<&[T]>, output: &mut [T], ) -> ProcessResult<()>

Process one block of signal.

fn reset(&mut self)

Reset the algorithm to its initial state.

fn metadata(&self) -> AlgorithmMetadata

Descriptive metadata (defaults to empty).

fn apply_command(&mut self, _value: T)

Receive a real-time command value from the control path.

fn init(&mut self, _sample_rate: f32)

Initialise the algorithm with a sample rate.

fn default() -> Self

Returns the “default value” for a type.
