How U determine first and second reflection points

Tvad, I think we'd exhausted the subject anyway.

Well Cdc, If you want to see that first reflecting point on a permanent basis I suppose that's useful - why else would you want a mirror on the ceiling?

Caught me!!

Tvad and snofun3 - LOL!!!!!

so if you where to hit my instrument and stand in front of it .Lets say you line all 4 walls with humans ,line all the ceiling and floor as well.when you hit the triangle(example)no other person will hear it but you becaue you block it ..right....life is 3d friends.......

I'm not sure what you are trying to say, but if you are saying that you need all of the reflections from the walls, ceiling, and floors to get 3d effect, you are overlooking the fact that on well recorded software that information is already there. To not treat the critical reflection points will distort the original signals and you will lose the value inherrent in making recordings using minimal mic'ing with realistic spatial information. In other words, there goes your depth of field everyone seems to think is so important.
