Struct Normalizer 

pub struct Normalizer { /* private fields */ }

Audio normalizer with RMS targeting and peak limiting.

Configuration

• target_rms: Desired RMS level in range [0.0, 1.0] (e.g., 0.5 for -6 dBFS)
• max_gain: Maximum gain multiplier to prevent over-amplification (e.g., 10.0)

Safety

All output samples are hard-clamped to [-1.0, 1.0] to prevent clipping.

Implementations

impl Normalizer

pub fn new(target_rms: f32, max_gain: f32) -> Result<Self>

Creates a new normalizer with the given target RMS and max gain.

Arguments

• target_rms: Target RMS level in [0.0, 1.0]
• max_gain: Maximum gain multiplier (must be positive)

Errors

Returns Error::InvalidInput if:

• target_rms is not in [0.0, 1.0]
• max_gain is not positive

pub fn normalize(self, samples: &[f32]) -> Result<Vec<f32>>

Normalizes audio samples to the target RMS level.

Arguments

• samples: Input audio samples

Returns

Normalized audio with target RMS level, all samples in [-1.0, 1.0].

Errors

Returns Error::InvalidInput if samples are empty.
