Export audio file? about web-audio-editor HOT 4 OPEN

Hi, unfortunately there is not such feature implemented. I wanted to add it, as the app itself is quite useless without this option, however, I'm quite busy with work related tasks all the time.

I found this http://stackoverflow.com/questions/16969201/web-audio-api-scheduling-sounds-and-exporting-the-mix which might be the way to go.

from web-audio-editor.

@janmyler There's a library for exporting to wav (which I've used here) and a somewhat hackily converted version for mp3 (which does seem to work but might be incredibly slow for longer tracks)

Feel free to take export.coffee from my audio editor, compile it online and drop it into your project (along with the workers). From there, usage is simple:

var number_of_channels = 2;
var oactx = new OfflineAudioContext(number_of_channels, sample_rate * length, sample_rate);

start_playing(from_position, oactx);

oactx.startRendering().then(function(rendered_audio_buffer) {
    export_audio_buffer_as(rendered_audio_buffer, file_type);
});

I am finding difficulties to save the project in DB and re render as it is saved , is it possible with it , then what is the idea to be used ?
