For those who are genuinely interested in hearing a 3D acoustic image from a traditional streaming stereo system or especially from a headphone rig, BACCH4Mac looks (sounds?) really interesting.
I am incapable of understanding, let alone explaining the theory that underpins how it works, but it is creating a real stir among the lucky few who have tried it.
After hearing just what a difference a decent DSP set up can make with the Dutch & Dutch 8C speaker system, I am more than a little curious about the BACCH4Mac.
Has anyone tried it and is able to share impressions with the rest of us?
If you find that speaker-room interactions impair much of the musical magic, or that headphones sound brilliant yet fail dismally when it comes to re-creating a credible, realistic 3D image, this might just be the answer for you.
Seems to be a stereo spatial filter, perhaps on a similar vein to Dolby Voice and other spatialisers … interesting with headphones many use cross feed filters to produce seemingly the opposite to what BACCH provides in producing a more ‘natural’ listening experience with headphones. Essentially BACCH seems to emulate with loudspeakers more of the unadjusted headphone listening effect.
I note from the FAQ that BACCH will produce an artificial stereo field with much contemporary mixed and produced music, but will work best or most accurately with straight/natural stereo recorded audio from a stereo microphone or microphones.
