The Web Audio API's MediaStreamAudioSourceNode()
constructor creates and returns a new MediaStreamAudioSourceNode
object which uses the first audio track of a given MediaStream
as its source.
new MediaStreamAudioSourceNode(context, options);
A new MediaStreamAudioSourceNode
object representing the audio node whose media is obtained from the specified source stream.
This example uses getUserMedia()
to obtain access to the user's camera, then creates a new MediaStreamAudioSourceNode
from its MediaStream
.
var audioCtx = new (window.AudioContext || window.webkitAudioContext)();
if (navigator.mediaDevices.getUserMedia) {
navigator.mediaDevices.getUserMedia (
{
audio: true,
video: false
}).then(function(stream) {
var options = {
mediaStream : stream
}
var source = new MediaStreamAudioSourceNode(audioCtx, options);
source.connect(audioCtx.destination);
}).catch(function(err) {
console.log('The following gUM error occurred: ' + err);
});
} else {
console.log('new getUserMedia not supported on your browser!');
}
