Does mid-side encoding work?

(1/1)

mattkhan:
I added a mid-side encoding option to DSP studio and played identical content on both L and R channels, the resulting L channel is identical to the input (i.e. what I expect to carry the Mid channel) while the resulting R channel (which I would expect to carry the Side channel) contains the same signal but -6dB lower.

It doesn't seem to match what I understand to be M-S encoding which is

M = (L+R)-6dB
S = (L-R)-6dB

given that L and R were identical, I'd expect the S channel to be completely silent

If I use a 3rd party MS encoder (e.g. http://www.voxengo.com/group/free-vst-plugin-download/#msed) then this behaves exactly as expected.

Is this feature broken?

Matt:
It is broken and I'm working on a fix.  Thanks for letting us know.

pluto:
Just to confirm that I concur that the mid-side functions don't work as expected.

ALSO, a brief question – why are there two functions, encode and decode, when this function ought to be fully symmetrical? I.e. the same function, when presented with either L/R or M/S, outputs the other.

steini0807:
würde mich auch interessieren was die Funktion macht und auch was die Funktion "Mittige Enkodierung" macht. Über die "Mittige Enkodierung" von JRiver finde ich überhaupt keine Info im Internet
