Thoughts on stereo field
Posted: Sat Feb 27, 2016 9:40 am
It's a bit theoretical, and I only need confirmation if the basic thinking is right or advices, if it's wrong.
My assumptions:
If two signals are the same and I send them to the left and right inputs of an audio chip, the result is mono.
If two signals are totally different and I send them to the left and right inputs of an audio chip, the result is binaural.
If two signals are basically the same but with slight differences and I send them to the left and right inputs of an audio chip, the result is stereo.
Regarding the last assumption, if I take that signal and split it, using synchronized low- and hipass filters (sync = same cutoff), then mathematically smooth the low signal's channels towards 0 (for an extreme example, a series of left -1,+0.5 becomes left -0.5, +0.25), I basically turn the low frequency signal towards mono. Accordingly, if I mathematically sharpen the high signal's channels towards max, I basically turn the high frequency signal towards binaural. In result the signal will gain more stereo depth (aka Stereo Imager).
Don't invest too much time to go in depth. First I need to just know if these basic thoughts are in any way correct?
