the upmix solution seems possible but there is not an echo function in avisynth :( the other function are already within avisynth (the separation of each channel, and the possibility to apply matrix file).

it seems to me soX (the tool used for the reverb is in open source so perhaps someone will made an audio filter for avisynth.
