Post Subject: Analog EnhancementPosted by Paul S on: 7/14/2021
Romy, during my own quest for a center channel I met (the late) James Bongiorno, all of which I've written about before at GSC. James was a passionate proponent of the center channel, and to that end he developed the Trinaural Processor, which is analog. James is gone now, and these might be hard to find, but they are the only analog center channel processors I know of. Conversely, when, over lunch, I talked about a center channel to a retired movie sound producer I know, he actually drew a passive mixer network on a napkin for me, and there wasn't much to it, basically scrubbing the gain from merging the channels and preventing blow-back. By telling this, I mean to say it CAN be done very simply, but that would not include the "cross phase injection" algorithm you've mentioned, and that James Bongiorno insisted was necessary to make acceptable "center fill" from stereo, which is processed in its own right in order that it be stereo, which JB believed is an un-natural and very compromised format to start with.
