Base64 decode causes out of memory

I'm using MP3RecorderJS. It workkd well except that when the audio I'm recording gets past about 30 seconds, it fails as Javascript throws an out of memory error, which is due to the base64 data being too big.

Here is the code I'm using:

  recorderObject.exportMP3(function(base64_mp3_data) {
    var url = 'data:audio/mp3;base64,' + base64_mp3_data;
  });

This is where it fails as the Ajax function that follows isn't being read.

As mentioned, it works when I record audio for 15-30 seconds. Longer than that and it fails.

Any help is very much appreciated.

you could lower the sampling rate maybe! – Ubdus Samad Feb 27 '17 at 14:10
how do I do that? – Lhen Feb 27 '17 at 14:21
Google it ,you must be using 44100Hz , slide it down to 22050Hz. – Ubdus Samad Feb 27 '17 at 14:24
lowered the sampling rate but it still produces the error – Lhen Feb 27 '17 at 15:01
hmm , you didn't get any increase in time limit ? if not use wav instead of mp3! – Ubdus Samad Feb 27 '17 at 15:10
if this ain't working , you can use an external library like this: https://plugins.jquery.com/jquery-record/ – Ubdus Samad Feb 27 '17 at 15:13
@UbdusSamad yeah. wav gets rid of the error. error now comes when inserting sending the wav data via ajax then decoding – Lhen Feb 28 '17 at 06:22
