pub struct WaveShaperNode { /* private fields */ }
Expand description

WaveShaperNode allows to apply non-linear distortion effect on a audio signal. Arbitrary non-linear shaping curves may be specified.

Usage

use std::fs::File;
use web_audio_api::context::{BaseAudioContext, AudioContext};
use web_audio_api::node::{AudioNode, AudioScheduledSourceNode};

let context = AudioContext::new(None);

let file = File::open("sample.wav").unwrap();
let buffer = context.decode_audio_data_sync(file).unwrap();
let curve = make_distortion_curve(2048);
let drive = 4.;

let post_gain = context.create_gain();
post_gain.connect(&context.destination());
post_gain.gain().set_value(1. / drive);

let shaper = context.create_wave_shaper();
shaper.connect(&post_gain);
shaper.set_curve(curve);

let pre_gain = context.create_gain();
pre_gain.connect(&shaper);
pre_gain.gain().set_value(drive);

let src = context.create_buffer_source();
src.connect(&pre_gain);
src.set_buffer(buffer);

src.start();

Example

  • cargo run --release --example waveshaper

Implementations

returns a WaveShaperNode instance

Arguments
  • context - audio context in which the audio node will live.
  • options - waveshaper options

Returns the distortion curve

Set the distortion curve of this node

Arguments
  • curve - the desired distortion curve
Panics

Panics if a curve has already been given to the source (though new or through set_curve)

Returns the oversample faactor of this node

set the oversample factor of this node

Arguments
  • oversample - the desired OversampleType variant

Trait Implementations

The number of inputs feeding into the AudioNode. For source nodes, this will be 0.

The number of outputs coming out of the AudioNode.

The BaseAudioContext which owns this AudioNode.

Connect the output of this AudioNode to the input of another node. Read more

Connect a specific output of this AudioNode to a specific input of another node. Read more

Disconnects all outputs of the AudioNode that go to a specific destination AudioNode.

Disconnects all outgoing connections from the AudioNode.

Represents an enumerated value describing the way channels must be matched between the node’s inputs and outputs. Read more

Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen. Read more

Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. Read more
