Recording mp3 on iPhone by SDK

I'm wondering if it's possible to record an audio file in mp3 format programmatically with Xcode.

I've read a tons of documentations and I've googled for this, but no result.

Please help, if someone knows how this is possible?

The iPhone SDK doesn't support MP3 encoding. It does support hardware AAC/m4a encoding which is in many ways superior to mp3.

AAC/m4a hardware encoding is supported starting in iOS 3.1 for iPhone 3GS and iPod touch (2nd generation) and in iOS 3.2 for iPad.

Take a look here:

I would start here

http://developer.apple.com/library/ios/#referencelibrary/GettingStarted/GS_AudioVideo_iPhone/_index.html,

try to record some raw sound file and then convert it to mp3 with some 3rd party library like LAME. You can pick up LAME source here:

http://lame.sourceforge.net/

Try building a static library for iOS / armv6, I actually managed to build it couple of minutes ago, but I'm too tired to try if it actually works :) There is probably no easy way to do this, hope this helps in your search. I will try LAME in the next couple of days and let you know however.
