I want to make a peak meter, specifically for output from the CD
audio via Quicktime (on Mac), but it could probably suffice to be a
meter on the audio in general. I can't find any specific support for
this on the Apple site, although I came across a dated example
(vu-meter.c) of a sound component for that. Would that still be
valid under OS/X? Any better examples? If I did use it, how exactly
would I use a custom sound component for my metering needs?
Hi Tab,
if you're investigating the use of an Audio Unit for this purpose, a
RMS driven VUmeter is part of my CAUGui SDK on my website. It's a bit
outdated (and the RMS code needs some tweaking), but it should be a
nice start into AU world.
I think another AU based meter is in Airy's .nib-based framework on
sourceforge: http://augui.sourceforge.net/
Cheers,
;) Urs
My version is not yet on sourceforge (still waiting to write the
CAUGui/AUGUI comparison...) but is freely available on demand.
Airy
