Getting digital sound into an accessable array
Author
How can I take say a wave file, and put it in a large array that hold the wave in a way where you could get the aplitude for any given exact time. Maybe have an array which held the aplitude of the sound for every 1/44,000th of a second. or whatever the frequency is. Thanx

do you mean aplitude or amplitude?
You would just load the wave into an array. At the frequency, you would have one sample per second, and then you would just read off the value of that part of the array. Although, you might want to do it a little bit at a time, as even a small sound sample would be several megabytes.

I meant amplitude... my m key on my keyboard is goofed. Anyway, so I have a wav and want to have the height of the wave at every (1/frequency)ths of a second and store it in an array. I guess I am wondering how to load it into an array.
thanx for the response!

You find out the file format, read it using file loading functions, allocate the correctly sized array (length depends on duration, data type depends on whether it''s 8, 16, or whatever bits per sample, and you will need 2 arrays for stereo). Then you just read in the values. Try www.wotsit.org to find out file formats. Once you have the file format, loading in a basic wave file is just simple C or C++ code.
