I'm developing a webapp that (in part) records some audio using recorder.js, and sends it to a server. I'm trying to target Firefox, so I have to use this hack to keep the audio source from cutting off:

// Hack for a Firefox bug that stops input after a few seconds
window.source = audio_context.createMediaStreamSource(stream);
source.connect(audio_context.destination);

I think that this is causing audio to be played back through the computer speakers, but I'm not sure. I'm kind of a newbie when it comes to web audio. My goal is to eliminate the audio that is being played out of the speakers.

EDIT:

Here's a link to my JS file on Github: https://github.com/miller9904/Jonathan/blob/master/js/main.js#L87

you have to connect the source to the node( through which you retrieve data which you are going to record), replace this.node with what variable name you have assigned to yuor node used for processing.

window.source.connect(this.node);
//this.node.connect(this.context.destination);

edit: just checked, connecting to destination is not compulsory, also make sure your node variable does not get garbage collected( which i am assuming is happening in your case, since recording stops after few seconds.)

  • Thanks, but it still doesn't work. I believe that the input cutting off is a documented bug in Firefox. I added a link to my original post to my Github repo for this project. – miller9904 Oct 01 '14 at 13:56
