this module was actually just a try-out of a code. though I found the response to different frequencies quite surprising. Has something like a fixed samplerate converter, though with higher frequencies, these come back in folding the stairs... just try it out, maybe you like it, maybe not...
Inlets

Outlets

Control Rate
int i;
for (i = 0; i < 16; i++) {
outlet_out[i] = (inlet_in[i] + inlet_in[15 - i]) >> 1;
}
