Provided methods

fn create_oscillator(&self) -> OscillatorNode<'_>[src]

Creates an OscillatorNode, a source representing a periodic waveform. It basically generates a tone.

fn create_gain(&self) -> GainNode<'_>[src]

Creates an GainNode, to control audio volume

fn create_constant_source(&self) -> ConstantSourceNode<'_>[src]

Creates an ConstantSourceNode, a source representing a constant value

fn create_delay(&self) -> DelayNode<'_>[src]

Creates a DelayNode, delaying the audio signal

fn create_channel_splitter(
    &self,
    number_of_outputs: u32
) -> ChannelSplitterNode<'_>[src]

Creates a ChannelSplitterNode

fn create_channel_merger(&self, number_of_inputs: u32) -> ChannelMergerNode<'_>[src]

Creates a ChannelMergerNode

fn create_media_stream_source<M: MediaStream>(
    &self,
    media: M
) -> MediaStreamAudioSourceNode<'_>[src]

Creates a MediaStreamAudioSourceNode from a MediaElement

fn create_media_element_source<M: MediaStream>(
    &self,
    media: MediaElement<M>
) -> MediaElementAudioSourceNode<'_>[src]

Creates a MediaElementAudioSourceNode from a MediaElement

fn create_buffer_source(&self) -> AudioBufferSourceNode<'_>[src]

Creates an AudioBufferSourceNode

fn create_panner(&self) -> PannerNode<'_>[src]

Creates a PannerNode

fn create_audio_param(
    &self,
    opts: AudioParamOptions,
    dest: &AudioNodeId
) -> (AudioParam<'_>, AudioParamId)[src]

Create an AudioParam.

Call this inside the register closure when setting up your AudioNode

fn destination(&self) -> DestinationNode<'_>[src]

Returns an AudioDestinationNode representing the final destination of all audio in the context. It can be thought of as the audio-rendering device.

fn listener(&self) -> AudioListener<'_>[src]

Returns the AudioListener which is used for 3D spatialization

fn sample_rate(&self) -> SampleRate[src]

The sample rate (in sample-frames per second) at which the AudioContext handles audio.

fn current_time(&self) -> f64[src]

This is the time in seconds of the sample frame immediately following the last sample-frame in the block of audio most recently processed by the context’s rendering graph.
