Hi I was looking up a CCRMA article on Schroeder Reverb built out of a 3 series allpass filters and 4 parallel comb filters, which are then fed into a mixing matrix which looks like this:

I tried using it and it sounded rather strange (quite psychoacoustic) due the the phase differences. Thanks! Emmett |

In general, the jumbling caused by mixing matrixes makes the reverb decay diffuse more naturally. Which article are you reading specifically? Also, creating an impulse response of the reverb and code would be helpful. On Dec 4, 2016 14:52, "Emmett Palaima" <epalaima@berklee.edu> wrote:
