Hi, hope everyone's been enjoying the holidays.
Anyway, I've been working on a Cocoa application that uses a simple Core Audio oscillator that I got from some sample code to play sound. I'm sending data to the oscillator in an array to generate sine waves, but I can't work out the syntax for how to do it.
Here's some of the code to show what I mean:
sinewavedef* def = defptr; // get access to Sinewave's data
int i;
// load instance variables into registers
double phase = def->phase;
double amp = def->amp;
double pan = def->pan;
double freq = def->freq;
NSArray * xArray = def->xArray;
NSArray * xArrayz = def->xArrayz;
double testArray[100][2] = def->testArray[100][2];
I seem to have no problem with NSArrays (though NMutableArray won't work), but I need to change the data in the arrays, so these are no good. I've tried all the variations of the last line I can think of, including the indeces or not including them, etc. And I can't find anything about it on the internet. I'm still pretty new to programming, so there's probably something really obvious I'm missing.
Can anyone help?
Hopefully, Simon
