QUADEK Digital Quadraphonic Audio Decoder
-- Bring back to life the sound of your quadraphonic records! --
QUADEK implements two algorithms capable of decoding four music channels out of a stereo track: QS method is best for “Quadraphonic Sound” recordings and SQ for “Stereo Quadraphonic” recordings. Both these quadraphonic technologies gained their fame during the 70s when many bands and musicians started to experiment with quadraphonic sound: Pink Floyd, King Crimson, The Who and Miles David, to name a few. There are hundreds of great records that came out with a “Quadraphonic” label and up to now could only be decoded with specialized hardware.
With QUADEK in your Mac (*) you can digitally decode those stereo tracks into quadraphonic surround and bring the experience of the quad sound into the 21st century!
(*) Your Mac should be hooked up to an audio interface with four available output channels that would need to be connected to your four speakers.
