Another option is interleaved(?) in one wav file.Ī word of warning: SQ and QS are CPU intensive. Output is channeled to a file recorder in Plogue that will save as individual wavs (4 or 5 if you want a Center, I don't do LFE that's always a problem waiting to happen). Worst case: you have to rip the source to wav or flac the run it. My old computer (Dell running "Vista" with onboard 5.1 card let me but my "newer" system (Dell running Win7 with a Nvidia graphics board with HDMI won't let me. "Real Time" decoding from a source depends on whether your computer/soundcard combination will let you use a "Duplex" setup with ASIO. Please give it a try, spread the word, and let me know what you think. It was years in creating, testing, and improving. I am a retired (disability) Electrical Engineering Tech (Associates Degree) so I always run a generation (or two) behind in the software/hardware area but I think I'm on the right track with this decoder. If you like it consider donating to help me improve it and fix any problems uncovered in the "launch". Like the upmix converter "SPEC" (also found at SBU) Multi-Matrix is Donationware. The download can be found in the SBU Wiki > General Techniques section. You'll have to register to download (but it's free). To get the Plogue Bidule layout for Multi-Matrix go to It decodes wav and flac files in "real time" and properly set up (with an ASIO driver) it can decode "on the fly" straight from vinyl, CD, and other sources. Also a "poor man's" vectorscope using a free VST.) If you rip vinyl the pre-processor can be used to correct minor set-up errors of your stylus and improve separation. There are occasional time-limited trial versions of Plogue but this program is worth the investment and some of the "toys" in the decoder may be useful enough to justify it for many of you (such as a pre-processor inspired by Lynn Olson's "Crosstalk Eliminator" to align phase, balance, and inject crosstalk canceling signals. It runs only in Plogue (sorry, haven't found a free VST host that is capable of math computations). It does SQ (Lynn Olson's "Shadow Vector" - Lynn is a heck of a nice man and was very willing to help me overcome early problems), QS (Vario-Matrix V2), EV-4 (passive), DY (passive with active center removal from rear), Dolby Stereo Surround (old style - not Pro Logic), Uniquad Equal Separation (an idea by Peter Scheiber that I found on MidiMagic's site). I will now make it available for your evaluation. When I came aboard I mentioned that I had a "Work in progress" computer-based decoder.
