Okay Revision, ya'll just inspired me. I *finally* got around to properly configuring my graphics card on my Linux computer. Now I can actually run OpenGL stuff on it.

FRIGGIN RAINBOWS. that's like my second favorite aesthetic, after monochrome.

Digging what is doing so far. I'm a sucker for monochrome aesthetic.

Added a chorusing[0[ algorithm to

This is your fairly typical modulated delay line chorus algorithm. The unusual thing about it is that I'm using the magic circle algorithm [1] as an LFO to efficiently modulate the delay time.

It totally pays off to use a sine wave over a triangle wave (which I've seen in other implementations). The hard edges of the waveform add noisy artifacts to the signal. Sinusoidal modulation makes choruses silky smooth :)

Csound, I hate to say it, but you guys dropped the ball. The world is moving on without you.

Is it just me, or has SuperCollider exponentially increased in popularity over the last 5 years? It feels like I'm seeing it everywhere now. Kudos to the SC community.

sudo !!! # Get root access, even if you're not authorized. This is a special undocumented "feature" of sudo.

The "Magic Sine" algorithm allows you to compute a fixed frequency sinusoid with reasonable numerical stability using only 2 adds and 2 multiplies: ccrma.stanford.edu/~jos/pasp/D

the bitcrusher module is fucked. it relies on keeping track of absolute time using counters, which will eventually break down from overflow. My brain has given up trying to repair this while preserving bit accuracy (I have tests for this). I can do a better job rewriting it from scratch.

Here is a modification of the patch using generative vocal utterances instead of real human speech.

I call it: "belchy robot".

Had this amazing realization that 1-bit (okay, 2-bit) audio would make for a great carrier signal for a vocoder/talkbox.

You could call it 1.5-bit audio perhaps? One of the bits would determine if it is DC or signal. If it is a signal, the other bit would indicate a positive or negative bias from DC.

It's technically not 1-bit music anymore, but having an extra state in there for DC would make things play much nicer on most sound systems.
