Struct FirEq 

pub struct FirEq { /* private fields */ }

FIR EQ generator: creates IR from band gain specifications

Implementations

impl FirEq

pub fn new(sample_rate: f64, num_taps: usize) -> Self

Create a new FIR EQ generator

Arguments

• sample_rate - Audio sample rate in Hz
• num_taps - Number of FIR taps (must be odd, will be forced to odd if even)

pub fn set_sample_rate(&mut self, sr: f64)

Set sample rate (triggers IR regeneration)

pub fn set_num_taps(&mut self, taps: usize)

Set number of taps (triggers IR regeneration)

pub fn set_phase_mode(&mut self, mode: FirPhaseMode)

Set phase mode (triggers IR regeneration)

pub fn set_band(&mut self, band_idx: usize, gain_db: f64)

Update a band gain (triggers IR regeneration)

Arguments

• band_idx - Band index (0-9 for standard 10-band EQ)
• gain_db - Gain in dB (-15 to +15)

pub fn set_bands(&mut self, gains_db: &[f64; 10])

Set all bands at once (single regeneration)

pub fn get_bands(&self) -> [(f64, f64); 10]

Get current band gains

pub fn get_ir(&self, channels: usize) -> Vec<f64>

Get current IR (interleaved for all channels) Returns IR repeated for each channel

pub fn ir_length(&self) -> usize

Get IR length (per channel)

pub fn num_taps(&self) -> usize

Get number of taps
