hi - sorry for the long absence!
Narbotic: I had already some wavetables in the making, if yours are vastly different I'm interested. Did you have a noise wavetable? I did not do this yet.
For noise I would just use the random function seeded with an analogread from an unused pin
adapted from the ardy reference:
int noisey;
void setup(){
Serial.begin(9600);
randomSeed(analogRead(5));
}
void loop(){
noisey = random(255);
Serial.println(noisey);
}
I'll post results when I give it a go.
I did not make the R2R board yet. Not enough of suited resistors in the box. Would 1K and 2 series 1K's work or is this too low resistance?
From what I've read those lower values might mess up the audio out levels, depending on what you play it through - amp, headphones, etc. But I may very be totally off-base here - definitely worth a try!
Did I see you with an oscilloscope? Might be easier to see what's happening.
yups - I love my scope! you can use software oscilloscopes with your sound card's input for low frequency investigations - very handy. I've used the SignalScope demo on my mac with good results.
just noticed this windows scope software in another thread -
