I want to setup a mike function in mobile app, but the program code is not work. The code is “var audioContext = new AudioContext();”, but it has error and no run any other code after it.

When I try other type of this function, I also get a same result.

var audioContext = new webkitAudioContext();  //Not work
var audioContext = new mozAudioContext();  //Not work
var audioContext = new oAudioContext();  //Not work
var audioContext = new msAudioContext();  //Not work

May I know how to setup recorder function of meteor mobile app, I want to use the function in mobile app, not mobile browser. Please tell me a correct method to setup a mike function. Thank you very much.

Same issue on windows. I use Meteor 1.4.4.6 and Chrome and Firefox. In the Console I have this error: playground.js?hash=d4cf45c097901d108c4fc6b87befc32f7078ba26:3 Uncaught ReferenceError: webkitAudioContext is not defined

Solved with set my variable differently :
try {
acontext = new webkitAudioContext();
} catch (e){
if (e instanceof ReferenceError) {
acontext = new AudioContext;
}
} // catch

instead of :

var acontext = new webkitAudioContext() || new AudioContext;
