How can I convert AAC sound files to MP3 files? For some reason, Powerpoint will not let me insert AAC files as sound files, so I'm looking for an easy way to convert about a dozen short AAC files so Powerpoint can recognize them.
What's the best way to compress a large mp3 file (70MB) to something that I can send via e-mail on AOL (limit 11 MB)? WinZip only compresses it to 68 MB? Any free programs do the trick?
