Hi Aleksey!

just yesterday, I found a very strange behaviour in "St Nicolaes Church" IM preset.

If you generate that impulse response and open it into an audio editor, you will discover a harmonically rich pitch (fundamental at 400 Hz) standing quite loud after the original "shot".  You can preview it on this image:

Is it maybe a denormalising or ringing error?

Thank you in advance for your help!

Cheers,

This is not a problem that much.  If you change the recepting walls a bit this will go away.  This is caused by some resonance that builds up in this design.  I can't tell what's it is about exactly, but changing recepting walls helps.

Thank you Aleksey, I'll try this night and I'll let you know the result.

Thank you again,

andrea

Ok, I resolved as you suggested.

I have simply reduced the recepting walls dimensions (probably too much large and opposing each other).  No more spurious reflections.

Thank you a lot for help!
