[−][src]Struct thorium::dmg_apu::PulseVoice

pub struct PulseVoice {
    pub play_samples_remaining: usize,
    pub sweep: FrequencySweep,
    pub envelope: LevelEnvelope,
    pub duty: f32,
    pub wave_point: f32,
}

A pulse voice produces a square wave with some optional effects.

  • The "sweep" effect can change the frequency. If frequency shifts out of range the sound stops playback.
  • The "envelope" effect can change the level of active sound moments in the square wave. When the sound level hits max or min it just stays there.\

Fields

play_samples_remaining: usize

How many samples are left to play out.

sweep: FrequencySweep

The sweep effect of this voice.

envelope: LevelEnvelope

The sounds level envelope of this voice.

duty: f32

The time percentage of "on" sound (0.0 through 1.0)

wave_point: f32

The current position within the wave pattern (<32.0).
