Struct BrickwallLimiter 

pub struct BrickwallLimiter { /* private fields */ }

Brickwall limiter state.

Implementations

impl BrickwallLimiter

pub fn new( ceiling_db: f64, lookahead_ms: f64, release_ms: f64, sample_rate: u32, channels: usize, ) -> Self

Create a new limiter.

• ceiling_db: ceiling in dBFS (e.g., -1.0)
• lookahead_ms: look-ahead time in milliseconds (e.g., 1.0)
• release_ms: release time in milliseconds (e.g., 50.0)
• sample_rate: audio sample rate
• channels: number of channels (typically 2)

pub fn default_safe(sample_rate: u32, channels: usize) -> Self

Create a limiter with default safe settings: -1 dBFS, 1ms look-ahead, 50ms release.

pub fn process(&mut self, data: &mut [f64], frames: usize)

Process a block of interleaved f64 audio IN PLACE.

REAL-TIME SAFE: no allocations, no locks, no I/O.

pub fn process_block( &mut self, input: &[f64], output: &mut [f64], frames: usize, )

Process a block of interleaved f64 audio. Correct look-ahead implementation.

REAL-TIME SAFE: no allocations, no locks, no I/O.

pub fn gain_reduction_db(&self) -> f64

Get the current gain reduction in dB (0.0 = no reduction).

pub fn ceiling_db(&self) -> f64

Get the ceiling in dB.

pub fn reset(&mut self)

Reset limiter state (call on track load or major discontinuity).
