[Swftools-common] Re: stereo sound(track)

[Russell Lyons]

P.S. The soundtrack noise from CS4 was from exporting raw sound; once I 
exported mp3, it was fine. So I have solved my problem by using CS4, but 
that is a huge pain to use. I'd rather use command-line tools, so still 
would like to have my questions answered.

Thanks,
Russ
