SURROUND I made this one just for fun, but does work. It enables you to out-stereo your sound!. It places the delay and detune outside your speakers. The concept is simple and is the same as the surround stuff from Behringer, JBL, etc. You just place the stereo signal out of phase on the opposite side and adjust the mix levels. It works really good with 2 tap stereo delays. But you should be careful with recordings because the phase shifting might give you more troubles then fun.

Hey all, Some important side notes and an improved and updated algorithm!!. One thing I forget to mention is that the stereo expanding sounds cool at home/with the band, but have to watch out with performing and recording. They may cause phase problems (duh!), which results in a weaker signal. I've made a new patch (Single S-Disc) with which you can "outstereo" the delay and/or the Dual Detune. I've tested it at home through my hifi with the speakers lined up next to each other (like a cabinet) and it sounded wonderfull. This line- up of the speakers, close next to each other, is important for the spacial effect. If the speakers were pointed towards each other, then the OUT OF PHASE signal would cancel=lower the volume of the original. Because guitarspeakers are next to each other, the OUT OF PHASE signal pushes the original signal futher away.......... voilą: MAXIMUM STEREO. But this is also the problem when recording this. If you would record it and listen to it on mono, or with the speakers facing each other, you (might) get weird stuff. So watch out, you got your sound faster destroyed then repaired. :o) #======================================================================= # (( SURROUND SOUND )) updated #======================================================================= # # Program: Surround Sound (updated) # Author: Maarten van Helden (mvh@vanhelden.demon.nl) # Date Created: November 9th 2000 # # Ever wondered how surround sound delays would sound through # your guitarspeakers?.
