I need to record audio through the HTML5, but you need to write directly in MP3. The reason is that in the standard version of the sound is written in WAV, 5 minutes = 500Mbit - this is a very high resolution. Write to WAV and then recode also tried (and client-side and server-side) - it is a very expensive process and takes a lot of time and resources (5 minutes of recording time is 5 minutes).

I need to write the sound directly into the format of MP3, convert for me is not suitable.I would be very grateful for any help.

  • where does the output audio file wind up ? server or browser side ? I believe mp3 encoding is patent encumbered so firefox wouldn't touch it with a barge pole – Scott Stensland Feb 06 '15 at 03:11
