Struct idsp::hbf::HbfDecCascade

pub struct HbfDecCascade { /* private fields */ }

Half-band decimation filter cascade with optimal taps

See HBF_TAPS. Only in-place processing is implemented. Supports rate changes of 1, 2, 4, 8, and 16.

pub fn set_depth(&mut self, n: usize)

Set cascade depth

Sets the number of HBF filter stages to apply.

pub fn depth(&self) -> usize

Cascade depth

The number of HBF filter stages to apply.
