Struct InputSignalModifier 

pub struct InputSignalModifier {
    pub which: DecorrelatorId,
    pub x_hist: Vec<Vec<(f32, f32)>>,
    pub y_hist: Vec<Vec<(f32, f32)>>,
}

Per-channel + per-decorrelator running state for InputSignalModifier. Carries the tail of x[ts-i-delay][sb] (input history) and y[ts-i][sb] (output history) needed by Pseudocode 111. Sized to the maximum delay+filterLength = 12 + 2 = 14 in the worst region; we allocate 24 per subband for slack.

Fields

which: DecorrelatorId

Decorrelator id (D0/D1/D2).

x_hist: Vec<Vec<(f32, f32)>>

x_hist[sb][k] = previous input sample at offset k slots in the past for QMF subband sb. Complex (re, im) pair.

y_hist: Vec<Vec<(f32, f32)>>

y_hist[sb][k] = previous output sample at offset k slots in the past.

Implementations

impl InputSignalModifier

pub fn new(which: DecorrelatorId) -> Self

pub fn reset(&mut self)

Reset the running history (e.g. on substream restart).

pub fn process_sample(&mut self, sb: u32, x_in: (f32, f32)) -> (f32, f32)

Process one (sb, ts) sample of the input matrix x. Returns the decorrelated output y[ts][sb]. The caller pushes the input (re, im) and receives the corresponding output.

Trait Implementations

impl Clone for InputSignalModifier

fn clone(&self) -> InputSignalModifier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InputSignalModifier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
