REQ: Weldroid Synesthesia x86

Synesthesia is a combined waveshaper / EQ / dynamics processor that is designed to be very light on the CPU, but to sound hi-fi enough to be put on the master buss without hesitation. A special combination of frequency-dependent harmonics generation and oversampling reduces aliasing way below audible levels, allowing smooth coloration of input material.
Synesthesia features flexible per harmonic definition of distortion / waveshaping characteristics, opening up possibilities to emulate static distortion of many nonlinear devices. Apart from the static waveshaping and equalization, dynamics processing is made possible by controlling a separate waveshaper curve with configurable attack and release time constants.
Features:
Static waveshaping.
Dynamic waveshaping.
Unique sounding 4-band equalizer.
DC filter.
Optional oversampling.
No latency.
No audible aliasing.
SSE optimized in assembly.
Easy on the CPU.
