Struct MultiBandDamping 

pub struct MultiBandDamping {
    pub center_frequencies: Vec<f32>,
    pub damping_coefficients: Vec<f32>,
    pub num_bands: usize,
}

Multi-band damping coefficients for efficient GPU computation.

Pre-computes absorption for multiple frequency bands to avoid per-sample FFT computations in the main FDTD loop.

Fields

center_frequencies: Vec<f32>

Center frequencies for each band (Hz)

damping_coefficients: Vec<f32>

Damping coefficient per band (linear multiplier per time step)

num_bands: usize

Number of frequency bands

Implementations

impl MultiBandDamping

pub fn from_environment( env: &Environment, time_step: f32, _cell_size: f32, ) -> Self

Create multi-band damping from environment conditions.

Uses octave bands from 31.5 Hz to 16 kHz (standard ISO bands).

pub fn single_band(damping_factor: f32) -> Self

Create simplified single-band damping.

pub fn damping_for_frequency(&self, frequency: f32) -> f32

Get the effective damping for a dominant frequency.

pub fn average_damping(&self) -> f32

Get average damping across all bands (for simple simulations).
