web.audio.AudioContext — clojure-interop/cljs-web-api 1.0.9

The AudioContext interface represents an audio-processing graph from audio modules linked together, each represented by an web.audio.AudioNode.

base-latency cljs

(base-latency this)

Property.

[Read Only] [Experimental]

The baseLatency read-only property of the web.audio.AudioContext returns a double that represents the number of seconds of processing incurred by the AudioContext passing the audio from the web.audio.AudioDestinationNode the audio subsystem.

var baseLatency = audioCtx.baseLatency;

close cljs

(close this & args)

Method.

The close() method of the web.audio.AudioContext Interface the audio context, releasing any system audio resources that uses.

var audioCtx = new AudioContext(); audioCtx.close().then(function() { ... }); await audioCtx.close();

create-java-script-node cljs

(create-java-script-node this
                         buffer-size
                         num-input-channels
                         num-output-channels)

Method.

[Obsolute]

The following script illustrates the use of createJavaScriptNode():

var jsNode = audioCtx.createJavaScriptNode(bufferSize, numInputChannels, numOutputChannels);

create-media-element-source cljs

(create-media-element-source this & args)

Method.

For more details about media element audio source nodes, check the web.audio.MediaElementAudioSourceNode reference page.

var audioCtx = new AudioContext(); var source = audioCtx.createMediaElementSource(myMediaElement);

create-media-stream-destination cljs

(create-media-stream-destination this & args)

Method.

The web.streams.MediaStream is created when the node is created is accessible via the web.audio.MediaStreamAudioDestinationNode's attribute. This stream can be used in a similar way as a MediaStream via navigator.getUserMedia — it can, for example, be sent to remote peer using the RTCPeerConnection addStream() method.

var audioCtx = new AudioContext(); var destination = audioCtx.createMediaStreamDestination();

create-media-stream-source cljs

(create-media-stream-source this stream)

Method.

For more details about media stream audio source nodes, check the web.audio.MediaStreamAudioSourceNode reference page.

audioSourceNode = audioContext.createMediaStreamSource(stream);

create-media-stream-track-source cljs

(create-media-stream-track-source this & args)

Method.

[Draft]

A web.media.MediaStreamTrackAudioSourceNode object which acts a source for audio data found in the specified audio track.

var audioCtx = new AudioContext(); var track = audioCtx.createMediaStreamTrackSource(track);

create-wave-table cljs

(create-wave-table this & args)

Method.

[Obsolute]

The web.audio.AudioContext method createWaveTable() is now you should instead use the method createPeriodicWave().

get-output-timestamp cljs

(get-output-timestamp this)

Method.

[Experimental]

The getOutputTimestamp() property of the web.audio.AudioContext returns a new AudioTimestamp object containing two correlated audio stream position values.

var timestamp = AudioContext.getOutputTimestamp()

See also: https://developer.mozilla.org/en-US/docs/Web/API/AudioContext/getOutputTimestamp

output-latency cljs

(output-latency this)

Property.

[Read Only] [Experimental]

The outputLatency read-only property of the web.audio.AudioContext provides an estimation of the output latency of the current audio

var latency = audioCtx.outputLatency;

See also: https://developer.mozilla.org/en-US/docs/Web/API/AudioContext/outputLatency

resume cljs

(resume this)

Method.

The resume() method of the web.audio.AudioContext interface the progression of time in an audio context that has previously suspended.

completePromise = audioContext.resume();

See also: https://developer.mozilla.org/en-US/docs/Web/API/AudioContext/resume

suspend cljs

(suspend this & args)

Method.

The suspend() method of the web.audio.AudioContext Interface the progression of time in the audio context, temporarily halting hardware access and reducing CPU/battery usage in the process this is useful if you want an application to power down the audio when it will not be using an audio context for a while.

var audioCtx = new AudioContext(); audioCtx.suspend().then(function() { ... });
