I wrote an Excel document to calculate early reflection delays, interaural phase delays of the direct sound, wall, air absorption and so on, BUT there is a problem. If I simplify the model to make it realizable by my VST plugins, I have to substitute head shading for panning and leave out interaural phase delays of the reflections - which leads to nothing but terrible results. I tried to invert the phase of the reflected sound and messed with mid/side surround but nothing seems to get close to the theoretically perfect model, realizable with a wave editor (very time and disk space consuming). So, Is there some plugin or application that features head shading (lowpass filtering of one channel in case the sound is too off-axis), adjustable absorption coefficients for side, read wall and ceiling (with a lowpass and highpass filter too, if possible), interaural phase delays of the direct sound and reflections, adjustable hall properities, instrument and "head" positioning?

I have no idea

Are you trying to determine if anyone else has been able to achieve this so that you can either give up or keep on hacking away at it?

Is this just a ridiculously fancy reverb, or does it sound cool on headphones?

Good Luck!

I''m not talking about reverb in general since late reflections (reverberation) are more or less a matter of accident. My area of interest is the first 80ms that come after the direct sound. Since these 80ms can be easily more than 50% of the total reflected energy, it''s very pleasing to hear a good simulation, especially with headphones.

Here''s the document if someone you''re interested, http://www.user661.wz.cz/articles/vhall/vhall.zip
but as I''ve said, the panning doesn''t work, it should be replaced by lowpass filters and int. phase delays.

i''ve done some very rudimentary binaural perception effects with the freeware modular vst maker, synthedit.. you should be able to translate your formula to it easily. i don''t have excel, and am not following why your model doesn''t translate to whatever you''re programming with, with ''panning..'' what''s hampering you from customising the ''stereoisation'' to your formula?

I''m not a programmer but a musician annoyed with results given by VST effects I''ve met so far, that''s why I''m not able to write my own application or VST plugin. Thank you for telling me about synthedit, let''s hope it''ll help.
