I imported a WAV file about 11MB in size and was compressed nicely by Flash. Published swf file came out to about 125kb.
Then I used Flash5 to import the same file converted into an MP3 (1.02MB). The resulting published swf file came out to be 1.02MB (the same size as that mp3 coincidentally).

I thought using MP3 would result in a much smaller published file ?

Getting back to the WAV file... it's currently 44000Hz 16-bit stereo... what should I convert it to for better playback (the current sample rate sounds too sharp when played thru swf). I believe it's 22000 Mono... what bitrate, etc.?

THANKS people.
