Audio Dispersion, Spectral Delay, and Tubes
I read everywhere that the speed of sound is approx. independant of frequency.
Unlike, stuff like optics where, depending on the medium, some frequencies travel faster than others.
But the other day I was talking to a guy involved in a company that outfits hi end audio gear for theatres, they were adding overhanging near field speakers to their range and
he was saying he had to get this DSP dude from france over to add special filters to correct the audio dispersion.
Anyway this got me experimenting, I found that spectrally delaying the lower frequencies could make a sound "bigger", especially base-drums, gives it a big "woosh" sound. Like the sound came from a large source some distance away. Also gives it a nice "compressor" sound which makes me wonder if tube compressors also exhibit some spectral delay.
So asking mixer freaks, what do you think of this?
