hi fons, hi everyone! playing with aliki and jconvolver again. i've recorded some sweeps from a single neumann kh120 loudspeaker into a tetramic. the IRs have been deconvolved and normalized, and after that their direct part and floor reflection have been trimmed off. now when i put those files in jconvolver with a gain of 1 (which is inserted into a post-fader aux fx bus), the reverb level is way too high. i see that you always use a gain coefficient of .5 in your b-format examples - why? i would like to start with the "correct" reverb level and go from there. the initial (peak) normalisation was done in ardour. maybe i should have normalized the initial impulse area to unit energy rather than the highest peak to unit amplitude, but i'm not quite sure how to accomplish that. the normalization feature in aliki doesn't seem to do anything, or i'm misunderstanding something. below is the config file. ignore the five inputs for now, the level problem is evident when using just a single input. any hints would be much appreciated, and yes, as soon as i've listened through these IRs properly and fixed the config, i'll be happy to share them with everyone. best, jörn /cd . # # # in out partition maxsize density # -------------------------------------------------------- /convolver/new 5 4 256 400000 1.0 # # # num port name connect to # ----------------------------------------------- /input/name 1 Input.LL /input/name 2 Input.L /input/name 3 Input.M /input/name 4 Input.R /input/name 5 Input.RR # /output/name 1 Output.W /output/name 2 Output.X /output/name 3 Output.Y /output/name 4 Output.Z # # # in out gain delay offset length chan file # ----------------------------------------------------------------------------------- /impulse/read 1 1 1 0 0 0 1 LL.wav /impulse/read 1 2 1 0 0 0 2 LL.wav /impulse/read 1 3 1 0 0 0 3 LL.wav /impulse/read 1 4 1 0 0 0 4 LL.wav /impulse/read 2 1 1 0 0 0 1 L.wav /impulse/read 2 2 1 0 0 0 2 L.wav /impulse/read 2 3 1 0 0 0 3 L.wav /impulse/read 2 4 1 0 0 0 4 L.wav /impulse/read 3 1 1 0 0 0 1 M.wav /impulse/read 3 2 1 0 0 0 2 M.wav /impulse/read 3 3 1 0 0 0 3 M.wav /impulse/read 3 4 1 0 0 0 4 M.wav /impulse/read 4 1 1 0 0 0 1 R.wav /impulse/read 4 2 1 0 0 0 2 R.wav /impulse/read 4 3 1 0 0 0 3 R.wav /impulse/read 4 4 1 0 0 0 4 R.wav /impulse/read 5 1 1 0 0 0 1 RR.wav /impulse/read 5 2 1 0 0 0 2 RR.wav /impulse/read 5 3 1 0 0 0 3 RR.wav /impulse/read 5 4 1 0 0 0 4 RR.wav -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net
