sorry, you're correct. i had an error in the code so it was wrongly
implemented. it does indeed work with negative values. thanks again.

Y
i just realized that this formula doesn't work with negative numbers.
for example: shifting a pitch down one octave over a duration from
0.0 to -0.5, or panning a source with a duration from center at 0.0 to
the left -1.0.
any advice?

graham, thanks for your patients and for the detailed response! i was
able to immediately solve my broken logic after reading it.
thanks again.

ok i'll use NSTimer instead of performSelector:withObject:afterDelay,
it should be easier to track this way. however, i'm still having an
issue with executing logic for the callback method:
so i set the timer to fire ever 0.15 seconds with this:
currentVolume =+ targetVolume / (fadeDuration / 0.

So just use NSTimer, within or without a wrapper object of your own devise.
Here's the basics of the code I used, whi
unfortunately i'm developing for iPhone OS (which i should have stated
earlier) so NSAnimation doesn't seem to be an option :-/

i'm attempting to fade out music by supplying a duration and a target
volume, but i'm running into complications.
for this example, the current playing volume is set at 1.0, i want to
fade the volume down to 0.5 over a duration of 4 seconds. this works
alright - it's not perfect because i'm using
11 matches
