I have a sound file I want to attach to an e-mail so I can send it to a friend. I originally had it in wav form with a size of 482 MB. I converted it to mp3 via iTunes, with a resultant size of 54.7 MB. It's apparently still too large to send (I think the largest size you can send as an attachment is 10 MB). Is it possible to compress it so I can send it as an attachment? Thanks for your help.
