Struct usfx::Mixer

pub struct Mixer { /* private fields */ }

Manage samples and mix the volume output of each.

// Instantiate a new mixer with a sample rate of 44100
let mut mixer = usfx::Mixer::new(44_100);

// Create a default sample as the sinewave
let sample = usfx::Sample::default();
// Create another sample with a trianglewave
let mut other_sample = usfx::Sample::default();
other_sample.osc_type(usfx::OscillatorType::Triangle);

// Play two oscillators at the same time
mixer.play(sample);
mixer.play(other_sample);

// This buffer should be passed by the audio library.
let mut buffer = [0.0; 44_100];
// Fill the buffer with procedurally generated sound.
mixer.generate(&mut buffer);

Implementations

impl Mixer

pub fn new(sample_rate: usize) -> Self

Create a new mixer object.

pub fn play(&mut self, sample: Sample)

Play a sample.

pub fn generate(&mut self, output: &mut [f32])

Generate a frame for the sample.

The output buffer can be smaller but not bigger than the sample size.

// Instantiate a new mixer
let mut mixer = usfx::Mixer::default();

// Create a default sample as the sinewave
mixer.play(usfx::Sample::default());

// This buffer should be passed by the audio library
let mut buffer = [0.0; 44_100];
// Fill the buffer with procedurally generated sound
mixer.generate(&mut buffer);

impl Debug for Mixer

fn fmt(&self, f: &mut Formatter<'_>) -> Result
