Hi there
I have doing some interesting experiments in time delay in ambient sounds
Much of this work was done in 1970s using the Haas & precedent effect towards the quadrophonic systems of the time and is often used in mastering even today
basically if you delay the onset of ambient info between 10-20 msec then you will here it as ambience and not added to primary wave front
An issue I have always had is as you amplify sound the ambience is amplified linearly
a certain amount can become correlated with the musical signal giving a "white noise" effect to high frequencies and a rather "dry" feeling to play back
Through experimentation with time delay in my cross over
I was able to decorrelate the ambience from the true musical frequencies at about 14msec in my set up
The differences are most impressive musically
