how does stereo enhancer work?
Hi,
I ask this because I think that the "mid" section is mono, right? which means that both the L and R channel are exactly the same.
And so, what is the "side" section? How does this work? Any thoughts thanks.
another way to ask is, how does L and R channels get converted to Mid and Side channels. Its the same
track, sounds the same, but you can make it mono say, below 300 hz, OK, fine. That is easy to understand, just sum L and R or whatever and make it mono. But, how do you get the "side" channel? When you began with L and R?

M = (L+R)/2
S = (L-R)/2
L = M+S
R = M-S
OK?

after a bit of headscratching and such, that DOES make sense...

[I have played with this plugin quite a bit]

When I was first grappling with the concept of M/S it helped me to use the other common naming, Sum and Difference, where sum is mid and difference is side. When you have stereo signal, sum is what is same in each of two channels (L and R) and difference is their difference. all width information is in that difference channel, so if you boost it, it exaggerates width and if you lower it, that narrows it.
It is really useful to use MS encoder and decoder plugins in chain and put any other plugin between them. Just remember to connect only 1st pin ins and outs for mid processing (so channel 2, the side bypasses it) and only connect 2nd pin ins and outs if you want to process side.
Remember that on their own two M/S channels are just two mono channels, and that side channel is usually pretty phasey and funky sounding on its own, but when you combine them with M/S decoder processor, the result is beautiful L+R stereo

stereo spreading can also be achieved by delay a bit one channel, not only using M/S techniques.
For instance, check DLM's Thr33some, which uses both techniques :

OK,
thanks for the descriptions and explanation.
Appreciate it
I will return to the plugins now for experimentation and see if I feel I really know how it all translates.

This is how I manually make stereo. 2 channels paned and one delayed a bit and a slight pitch shift too.
