Re: Grey Noise

Hi there,
 
I need to generate grey noise in openal but don't think there is any predefined way of doing it. Only white noise can be generated in openal but what about grey and pink noise. Is there any way to do it. If I generate by using just 'C' then after loading it in openal buffer, while playing I experience clicking. Thank you for help in advance.

Neither OpenAL nor ALUT can generate grey or pink noise.

With your own noise buffer, you're probably getting clicking because the sample at the end of your buffer doesn't match up with the sample at the beginning (even noise has to have continuous samples).

If you were generating sine waves, I'd tell you to make sure you size your buffer as a function of the frequency (so the samples at the beginning and end were both near zero), but I'm not sure what to suggest with a noise waveform (I don't know what parameters go into a particular noise function).
