AAC gives maybe half the file size of the equivalent quality for mp3. I guess if 
a factor of 1.7 to 2 is important to you, search for an AAC solution, otherwise:

lame --preset extreme file.wav file.mp3

gives you a variable bit rate codec which you won't know from the original. And 
you can write a script to pipe flac into lame, presumably even on windows ;)

lame is kindof a standard, and will always be available. Tools of the trade :)
