Hallo!
Scr_gain: no such object Room_sim_3d: no such method for 'room_sim_3d'
Using the help room_sim_2d room_sim _3d-patches, it is also not possible to add a third source (to me). Are these objects restricted to two sources (which would be contradictory to the iem reports e.g. 38/7)?
I know these objects are not so easy to use ... ;)
However, which version do you use ? The one from pd extended or did you compile it yourself ?
I made a tutorial for the LAC, where the roomsimulation is also included (last patch): grh.mur.at/PdSpatialization.tar.gz
Or you can get the patches (and externals) from the author (Thomas Musil) here: http://iem.at/~musil/Binaural_Ambisonic/
