Struct GainBlock

pub struct GainBlock<S>
where
    S: Sample,
{
    pub level_db: Parameter<S>,
    pub base_gain: S,
    /* private fields */
}

A gain control block that applies amplitude scaling.

Level is specified in decibels (dB).

Fields

level_db: Parameter<S>

Gain level in dB (-80 to +30).

base_gain: S

Base gain multiplier (linear) applied statically to the signal.

Implementations

impl<S> GainBlock<S>

where S: Sample,

pub fn new(level_db: f64, base_gain: Option<f64>) -> GainBlock<S>

Create a new GainBlock with the given level in dB and an optional base gain multiplier.

pub fn unity() -> GainBlock<S>

Create a unity gain (0 dB) block.
