Crate web_audio_api
source · [−]Expand description
A high-level API for processing and synthesizing audio.
Example
use std::fs::File;
use web_audio_api::context::{BaseAudioContext, AudioContext};
use web_audio_api::node::{AudioNode, AudioScheduledSourceNode};
// set up AudioContext with optimized settings for your hardware
let context = AudioContext::default();
// create an audio buffer from a given file
let file = File::open("samples/sample.wav").unwrap();
let buffer = context.decode_audio_data_sync(file).unwrap();
// play the buffer at given volume
let volume = context.create_gain();
volume.connect(&context.destination());
volume.gain().set_value(0.5);
let buffer_source = context.create_buffer_source();
buffer_source.connect(&volume);
buffer_source.set_buffer(buffer);
// create oscillator branch
let osc = context.create_oscillator();
osc.connect(&context.destination());
// start the sources
buffer_source.start();
osc.start();
// enjoy listening
std::thread::sleep(std::time::Duration::from_secs(4));Modules
The BaseAudioContext interface and the AudioContext and OfflineAudioContext types
Convenience abstractions that are not part of the WebAudio API (media decoding, microphone)
The AudioNode interface and concrete types
Primitives related to audio graph rendering
Structs
Memory-resident audio asset, basically a matrix of channels * samples
Options for constructing an AudioBuffer
Represents the position and orientation of the person listening to the audio scene
AudioParam controls an individual aspect of an AudioNode’s functionality, such as volume.
Options for constructing an AudioParam
PeriodicWave represents an arbitrary periodic waveform to be used with an OscillatorNode.
Options for constructing a PeriodicWave
Enums
Precision of AudioParam value calculation per render quantum
Constants
Maximum number of channels for audio processing
Render quantum size, the audio graph is rendered in blocks of RENDER_QUANTUM_SIZE samples see. https://webaudio.github.io/web-audio-api/#render-quantum
