Recording Audio From Web Page

Question

I'm looking for a solution for capturing audio from a user's microphone and posting it (preferably as MP3) to a server. I need something that I can embed in a web page.

I've seen where Flash can do this, but I understand that this approach requires expensive server-side software from Adobe. I'm not aware of whether Silverlight may provide any capabilities to assist with this.

I'm curious what others have done. Any advice would be greatly appreciated.

Answer 1

SilverLight 4 now has the ability to record audio. http://blog.ondrejsv.com/post/Audio-recorder-Silverlight-4-sample.aspx shows encoding PCM to WAV

Answer 2

Silverlight does not have this capability, currently (or in their upcoming 3.0 release). Flash would be the way to go.

Answer 3

You can do it with Flash and either Red5 or haXeVideo or the server, both Open Source. Regarding offering a final MP3 to the user, you will need something else because these 2 tools only record to FLV format due to the licenses needed to encode MP3s. You can use something on the server such as FFMPEG for the transformation, but still, read the small print regarding MP3s.

Good luck
