Question

I have a blob data in this structure:

Blob {type: "audio/wav", size: 655404, slice: function}
size: 655404
type: "audio/wav"
__proto__: Blob

It’s actually sound data recorded using the recent Chrome getUerMedia() and Recorder.js

How can I upload this blob to the server using jquery’s post method? I’ve tried this without any luck:

   $.post('http://localhost/upload.php', { fname: "test.wav", data: soundBlob }, 
    function(responseText) {
           console.log(responseText);
    });

You can use the FormData API.

If you’re using jquery.ajax, you need to set processData: false and contentType: false.

var fd = new FormData();
fd.append('fname', 'test.wav');
fd.append('data', soundBlob);
$.ajax({
    type: 'POST',
    url: '/upload.php',
    data: fd,
    processData: false,
    contentType: false
}).done(function(data) {
       console.log(data);
});
