recording three signals to stereo, but keeping seperation

[oinkbanana]

who sells/makes a matrix box that will mix three signals down to two (for recording)


A, B & C encoded to A+B left and A+C right
later i can decode it (to three isolated signals) removing the common A from both sides in a DAW



something like a fake MS, but the side takes two signals instead of a figure 8 doubled and phase flipped....


i'm sure this exists, but i might have imagined it.

this may help if you have more details, situation perhaps...? and what are you trying achieve?
signals are lines or mics?

[oinkbanana]

mic levels. xlr.

umm... won't this be a matter of decoding at the recording stage if you are working with 3 separate signals instead of 2?

i think if you are going B (hard left) + A (Center) + C (hard right) down to stereo with a mixer and decode it in your DAW, this way you will get a good phase cancellation for the A right? but i think the B + C will sound weird tho...

i'm not sure.....

exactly. just figured there was a specific box for this that I could use instead of a mixer.
something built specifically like an MS encoder/decoder box
