you can...buts its rather stupid to do so...why?, because you are compressing an already compressed file (assuming you are talking about a file other than a .wav file)...the more you compress an audio file, the lower its kwality gets..

how a file gets compressed for online sharing:

one starts by ripping a file from a CD...said CD has the .wav forms of the files (though they are in .cda format, as that is how a commercial cd is manufactured)...you can rip as a direct copy in the form of .wav, or you can directly go to mp3 (or other) format with a compression factor of your choosing...in general, ppl who are kwality minded will choose a bitrate of 320kb/s...192kb/s is the standard scene release bitrate....128 is the bare acceptable minimum

in a nutshell, just reacquire a desired file at a lower bitrate (which = smaller file size)...that is assuming you are looking for a smaller file size...
