Code:
output = (buffer[a] + output)/2;
This part I don't quite understand, the number of samples is 44100 a second, and at the moment it is a 10 second sine wave, and this can change....

That is correct, although I thought that having the following line would keep adding the current value of the sine wave 'a' into output and it would build up until all 34 waves are together as one sound.

Heres the whole part of the code, including both loops.
...Code:int main() { //Create ne wav file CWavFile file; file.newWav(SR, 16, 1000, 1); float f = 10; //frequency float PIX2 = PI*2; float wave; float gain; int g = 0; float buffer[34]; //no. voices for(int a = 0; a < 34; a++) { gain = 1; for(int i = 0;Leave a comment:

'a' refers to an integer, which is declared previously as part of another while loop to allow the program to run through the above piece of code for each instance of a sine wave. The buffer is merely there to hold the samples before it is then added to 'output'.
Hope that helps...Leave a comment:

I did expect that to happen but i'm not getting that, all I would get at the end is a sine wave at say 320Hz.
The problem is that the sine waves don't seem to combine...Leave a comment:

Help with Additive Synthesis
Hi, i've been trying to combine a number of sine waves together for the past few days without any luck. No processes i've found on the internet seem to work for me.
I have code which creates different sine waves at different frequencies, but it always only plays the final frequency, so any pointers on what I should do with this code would be appreciated.
...Code:for(int i = 0; i < file.getNumSamples(); i++) {
