Sanri,
NSLevelIndicator is not available in 10.3. If 10.3 is your platform, then
you're out of luck.
QuickTime 7 has some new functions that make this kinda easy. See the
documentation:
<http://developer.apple.com/documentation/QuickTime/APIREF/ModifyingMoviePro
perties.htm#//apple_ref/doc/uid/TP40001187-DontLinkChapterID_1-MeteringSound
LevelandFrequency>
You may also want to look at the old way of doing things. the sndEqualizer
sample code at the QuickTime Reference Library page is a good place to start
with the basic concepts.
later,
douglas
