how to generate random noise without making function calls? 2007-11-09T01:11:51+00:00 hi, i've read in the sticky, that you should keep function calls outside of the processReplacing() function, but i don't know how i would do that now. i just modified the again.dll (my first succesful sound woot(thanks to everyone that helped)) the only things that are different is this function at the top of the again.cpp: #include <time.h> #define RANDoMAX int(0xFFFFFFFF*0.5f) float GenerateRandomNumber( void ) { /* Change this for different random sequences. */ static unsigned long randSeed = time(NULL); randSeed = (randSeed * 196314165) + 907633515; return float(randSeed); } and the process and double process functions: //----------------------------------------------------------------------------------------- void AGain::processReplacing (float** inputs, float** outputs, VstInt32 sampleFrames) { float* in1 = inputs[0]; float* in2 = inputs[1]; float* out1 = outputs[0]; float* out2 = outputs[1]; while (--sampleFrames >= 0) { fGain = GenerateRandomNumber()/float(RANDoMAX); fGain -= 1.0f; (*out1++) = (*in1++) * fGain; (*out2++) = (*in2++) * fGain; } } //----------------------------------------------------------------------------------------- void AGain::processDoubleReplacing (double** inputs, double** outputs, VstInt32 sampleFrames) { double* in1 = inputs[0]; double* in2 = inputs[1]; double* out1 = outputs[0]; double* out2 = outputs[1]; double dGain = fGain; while (--sampleFrames >= 0) { fGain = GenerateRandomNumber()/float(RANDoMAX); fGain -= 1.0f; (*out1++) = (*in1++) * dGain; (*out2++) = (*in2++) * dGain; } } so how would i fix that to work without the function call. is that where these "virtual" functions come in?? also. again no longer works as a gain plugin. just outputs white noise. laserbeak https://www.kvraudio.com/forum/memberlist.php?mode=viewprofile&u=334

there was a joke you missed. Any programmer must be obsessive compulsive to a high degree in order to get anything done in the first place.

i agree. i don't remember what i was thinking exactly, but it provoked a nice detailed explaination(IMO) so i'm happy
