White noise wavetable

I'm not at my S|M machine, but you can hook up the random generator and normalize it then use a loop to load a float array with random values and then the text save to write them to a file.

It won't sound very much like white noise though becuase of the repetition of the same pattern over and over.

i'm not exactly sure what white noise is, but you can turn the noise from the multi osc into a text file easily.

just take the multi osc set it to noise and then connect that to the analizer primative, and set the analizer to 256 samples, now you can connect up a draw graph to that.

then just connect a float component to the freq on the osc, if you play around with different frequencies you will get different random patterns.

to turn it into a text file just connect a text component after the analizer.

and then you have noise in a text file.

the thing is though that now that it's a text file it's no longer proper noise it just sound s like a fuzzy high pitched sound, i think this is because the output of the wave should be constantly affecting the phase input, where by now that you have it as a text wave it's just a normal wave.

i had a little go at this and you still need to feedback the output back into the phase input (multiplied by 1000) for it to sound like noise.

I'm with Exonerate: white noise in a wavetable oscillator is a bad idea.

Thanks Exo and RL. I wondered why my attempts to produce white noise text file were failing. Oh well. There goes that short cut!
