This crazy dude has managed to squeeze REAL TIME AUDIO effects out of the stock, 1 MHz Commodore 64.
It does filter/EQ, echo, tube distortion, ‘Grungelizer’, compression, dithering, VOCODING and TIME STRETCH. Really ridiculous.
You can download the demo from CSDb and we’re waiting for YouTube recordings of real machines to show you, if they don’t show up tomorrow I’ll make one from my SX-64 (though I wonder if this works on NTSC. We’ll try).
Emulator’s not gonna be good on this one, maybe except HOXS64
