Console
SPU rate reduction, true 4-bit ADPCM grain, and freeze-stutter hiccups.

Real '90s console audio: SPU-style Gaussian rate reduction on top, a true 4-bit ADPCM encode in the middle, and a small dark ambience that grows as the fidelity falls. Full stereo. It is less about destruction than that soft, rounded, slightly haunted game-soundtrack glow.
The macros here
- AmountDrops the internal rate from 32 kHz toward 11 kHz, closes the lowpass from 12 kHz toward 4.5 kHz, and raises the built-in ambience (about 8% to 22%).
- ToneScales the lowpass ×0.7–1.6 — from murky to surprisingly open.
- NoiseA quiet digital hiss bed.
- DropoutsEmulator hiccups: freezes with a slight pitch drop, and stutters.
