TYPE: The type of the wave (random or sawtooth) CUTOFF: How many higher harmonics can go through RESONANCE: No clue how to explain this one, it's weird. Here's a simple lowpass biquad filter taking out the highs in the waveform. I'm going to try to implement some sort of FFT in the future so you can see the filter sweeping in action. This is an IIR filter, which means that it is infinite impulse, which is an easy way of saying it can self oscillate. Like an FIR filter, it needs coeffs to run, but it's only 5 coeffs (that's low). This can be used as an alternative to Perlin Noise, but this can be a bit more rigorous on CPU. You can also have multiple orders, which is a fancy way of making the filter sweep thingy tighter. Oh yeah I'm also back and have a whole new arsenal of M A T H :P If there are any bugs, I made this during the middle class and they were loud sorry
