Hello all, I've been playing around with encoding/mixing some four channel tracks down into stereo using the two simpler non-phase shifting formats, Dynaquad and EV-4, in Audacity with little success.
I start by splitting the front and back stereo tracks into four single left/right tracks and duplicating them into eight so I can apply their respective inverting/amplification values to achieve the two L/R Total tracks. So, using Dynaquad's formula for example, for LT I keep LF as it is, reduce RF to .25 (about -12 dB), keep LB as it is, and invert RB while reducing it by .5 (-6 dB). I then take these modified four tracks and mix them down into LT (which actually has a separate right track (thus stereo)) and repeat the procedure for RT, but swapping values/polarities. In the end I get two complex stereo channels which I reduce down into one.
Now, I believe I was doing things right until I began decoding it using a slew of receivers and adaptors, ranging from my main Toshiba SA-504 on its RM setting, my Lafayette LR-220 on its "Composer" setting, and a crummy Realistic Quatravox box with absolutely no success. For starters, I do get frontal stereo separation, but the back seems nonexistent, perhaps even mono. Now, I know Dynaquad/EV-4 practically has no back stereo separation (2 dB if I recall), but I should at least hear something moving around. I also hear hardly any of that ambient out of phase difference in the back, and my test tracks contains a lot of stereo reverb. My only guess is I should mix the 'unwanted' channels (like RF/RB in LT and LF/LB in RT) in mono and then mix them in instead of having them retain their stereo information.
Any suggestions are welcomed!
Thanks!
