Crate rawdio

source ·
Expand description

rawdio is an audio engine that is inspired by the Web Audio API

You can use it to:

  • Create a context
  • Create DSP nodes
  • Connect the nodes together
  • Accurately schedule ‘events’
  • Process the graph with an input and an output

Example

use rawdio::{connect_nodes, create_engine, AudioProcess, Context, Oscillator, OwnedAudioBuffer};

let (mut context, mut process) = create_engine();

let frequency = 1_000.0;
let channel_count = 2;
let oscillator = Oscillator::sine(context.as_ref(), frequency, channel_count);

connect_nodes!(oscillator => "output");

context.start();

// Call `process.process(...)`, passing in the input samples, and using the output
// If you wish to use with your sound card, you could use something like cpal (see the examples)

Modules

Macros

Structs
