Struct Fdn 

pub struct Fdn { /* private fields */ }

Feedback Delay Network for late reverb synthesis.

N delay lines (default 8) with a Hadamard mixing matrix for energy-preserving feedback, per-line lowpass absorption for frequency-dependent decay, and stereo output tapping.

Implementations

impl Fdn

pub fn new(num_lines: usize, sample_rate: u32) -> Self

Create a new FDN with num_lines delay lines.

num_lines must be a power of 2 (for Hadamard matrix). Typical: 8 or 16.

pub fn set_room_params( &mut self, rt60: f32, damping: f32, size: f32, sample_rate: u32, )

Configure room parameters.

rt60: Reverb time in seconds (0.1 - 10.0) damping: HF damping (0.0 = bright, 1.0 = dark) size: Room size factor (0.5 = small, 2.0 = large)

pub fn process_stereo(&mut self, left: f32, right: f32) -> (f32, f32)

Process one stereo sample pair through the FDN.

Input is mixed into all delay lines. Output is tapped from all lines.

pub fn reset(&mut self)

Reset all delay line state.
