My email can handle wavs up to 20MB but it's not very reliable.
The easiest way is to upload the wavs to my server using FTP.
I can set up a temporary password and folder for you and you can either use your browser or a shareware FTP application. Just email me direct.
When ya send the file btw: send me an entire .wav from beginning to end.
In other words, include any silence at the beginning etc...right from the beginning of the song. That way I can just drop your wav into my software and it should sync up no problem.
