Recoder.js not working for MAC firefox < 43

[rmehta68]

I am trying to record voice using the recorder.js, it is working fine for all the browsers on windows and MAC except MAC Firefox old versions, on current versions i.e 43 it is working fine but when I tried same for Firefox 42 and 41, a broken .wav file was created on the server.

Code used to export recorded sound to wav file :-

recorder.exportWAV(function (wav) { var url = (window.URL || window.webkitURL).createObjectURL(wav); $(".recordr").jPlayer("setMedia", { wav: url }); });
