I am trying to find out the length (in seconds or milliseconds) of a sound that is of type FSOUND_SAMPLE*
I can get the number of samples in the sample by calling FSOUND_Sample_GetLength()
Now I need to know how to covert that into a time based figure…
Is there a way of getting the sample rate for a sample? – I am assuming that I need to calculate the number of samples per second in order to work out the length of the sample.
Thanks for any help
If you need a value in milliseconds, and you’re running at 44,100 Hz, here’s some code (let’s pretend lSamples is the variable holding your sample count):
fSeconds = (float)lSamples / 44100;
fMillisecs = fSeconds * 1000;
It’s important that at least fSeconds be floating-point, or you will end up with an integer, which can’t represent fractions of a second. fMillisecs CAN be integer, but if it is, you need to typecast, and that’s why I made it floating-point.
The thing is, I don’t want to have to restrict the sounds I am using to be 44100 or any other fixed sample rate.
In fact because of the context, some of the sounds being used are sampled at 22050
What I want is a function to tell me what the sample rate of the sample is, which I can then substitute into a formula like the one you provided.
p.s. I know C++ quite well
