Struct thorium::dmg_apu::LevelEnvelope

pub struct LevelEnvelope {
    pub rate: i8,
    pub level: f32,
    pub samples: usize,
}

Fields

rate: i8

How often to adjust the envelope up or down.

• Given in 1/64th Sec units, correct range is +/- 7.
• Use 0 for no envelope update.

level: f32

The level (0.0 through 1.0) when the sound is "on"

samples: usize

How many samples until we trigger the envelops and re-assess things.

Methods

impl LevelEnvelope

pub fn samples_until_trigger(rate: i8, samples_per_second: i32) -> usize

Computes the samples until the envelope triggers

pub fn new(rate: i8, level: f32, samples_per_second: i32) -> Self

Constructs a new LevelEnvelope with a correct samples remaining.

pub fn tick_sample(&mut self, samples_per_second: i32)
