QUARK enables semi-binaural listening via standard 2-channel playback or 4-speaker listening via Involve Audio hardware decoders, vintage Regular Matrix quadraphonic receivers, Dolby Pro-Logic II receivers (which is virtually every surround sound system made from 2001 to today), or any multi-channel audio interface equipped computer by using the “decode” function of QUARK by routing the audio from your playback browsers through your Digital Audio Workstation such as Reaper, Pro Tools, Logic or Ableton Live. You may also want to use a virtual audio device application like Loopback or BlackHole for more complex internal routing.
A couple of people on the Quadraphonic Quad forum used JUCE and BlackHole to build a stand alone app. Franck made a great video based on instruction from BJMarsh. Many of you probably don’t have Xcode on your computer so here is the already compiled app for download. Just use the instructions on the video starting here. You’ll also need to “Allow Microphone Access” and you also may need to do this to convince your Mac to open the app.
Also, the Stereo Lab software (by Richard Brice) is excellent for offline processing/decoding spatial audio music into discrete tracks. It does all kinds of other amazing tricks too. The difference that is this software does not process in real time like QUARK does.
