I got a problem I need to work out, and its actually about JK (i'm not trying to post my homework on here or anything). Before I give you the problem, i'll explain why I need it, that might help you visualize it btter.

I have a cog that slows the speed of my wav file to 1/2 speed, and it does this in 0.05 seconds.

I need to know how much of the wav file has been played (in time) by the time that it reaches 1/2 speed. Get it?

I need this number so I can add exactly that much dead space in the beggining of my wav file, so i don't hear the 1st word in my wav file all fast.

Unfortunently, it seems to me that integrals might have to be used to figure this out. And although I can solve integrals, I don't know how to create them. lol. stupid calculious class never teaches you the important stuff. they always start the problems in the middle.

Well... I can't help you, but I can give you this hint:

Use the cog forum.

The most important information needed to solve this problem is HOW the WAV file is slowed, is it in a linear fashion, or in an exponential fashion? Then we can worry about integrals...

I'm not really sure what you're asking there.
What is 0.05 seconds?

What I am asking is that between time 0 and time 0.05 there is a rate of change, we simply need the Nature of the rate of change in order to determine exactally how much time is used there...

Well West Wind, since it slows the WAV down according to time, I would think it HAS to be done linearly. It only makes since, I mean, dividing the time up into segments equal to the amount of speed steps would be the easiest way to do it, and I'm sure the programmer made the comp slow down WAV files the easiest way.

BTW, why the hell did this topic get kicked out of the general forum? Put it in the cog forum? IT HAS NOTHING TO DO WITH COG! Geez, say the word "cog" once in your post and people get confused.

Well... Ok then, it belongs in the Main Editing Forum. Why would it belong in the Discussion Forum?

It does not HAVE to be done linearly... It most likely is done linearly, but it could be done exponentially... A good mathematician always checks...

Oh, yeah... and Sith_lord, the number your looking for, assuming it DOES decrease lineraly... is .0375 Seconds... You really dont need any integrals, you can just draw it out and use simple geomitry on the areas... but if you are interested, I think what you have is:
The Integral of (-10*x + 1) with respect to X over the inteval of 0 to .05.

Yeah, der, seems like it would work. Integrals are evil, i've trained my mind to forget them. You are uber smart man. I'm happy i changed my major from math to computer science, cuz i know Math is just gonna get harder and harder after calculious.

THANK YOU

0.05 seconds is almost instantaneously, why does there need to be a delay at all?

Because the wav file speed is set to double, and when it slows from double to half (which is really normal speed) it is very noticeible because of the high pitch.
