The only thing I need is mix the audio files, I need to manage the volume of those files and finaly export an audio file .wav

I was searching in the internet but don't find nothing. Could I use javascript o some plugin to do it?

Thanks and I hope you can help me.

  • what you mean by mix? Add one after the other? You could prbably handle this better by server – juvian Jul 04 '14 at 17:45
  • no, i mean get a new audio file that sounds like the other two was playing at the same time. – Carlos Jul 04 '14 at 17:47

  • these won't work since he want to export as wave and not play them – ESD Jul 04 '14 at 17:54

    Well, in that case it needs to be handled by server – juvian Jul 04 '14 at 17:55
  • Do you know how to do it by server? – Carlos Jul 04 '14 at 17:57

You will need to upload both the file to the server and then run some digital signal processing algorithms to mix the two signals. Once done, return a link to the file.

Here are some books on dsp for audio : http://www.amazon.ca/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=digital%20signal%20processing%20audio

I suggest asp.net mvc or ruby on rails for this project.
