Welcome to Universal BACCH. u-BACCH is a series of stereo speaker filters that create a 3D soundstage from any stereo content played through symmetrically placed, matched speakers. This is achieved through our patented, best in class, cross-talk cancellation filters. Our filters are industry leading with no coloration, tonal distortion, or dynamic range loss. So you can hear exceptional 3D audio over stereo speakers any time, with no penalty.

SETUP
uBACCH u-BACCH is a series of cross-talk cancellation filters based on the half-span angle of the speakers at the listening position, ranging from 1 to 90º.
You can imagine the two speakers and listener as forming a triangle: In an equilateral setup where the distance between left and right speaker is the same as the distance from either speaker and the listener, then the angle of the speakers would be 60º. To get your half-span angle, you’d simply divide that in half to get 30º.
EXAMPLES
A lot of studio monitoring situations will have stereo speakers with half-span angles anywhere from 20-35º (or higher).
A far-field listening room may have speakers from 15-30º.
A computer with symmetrical speakers to each side of the keyboard would be somewhere from 12-18º, a tablet held horizontally would be a similar range, and a soundbar several feet away could range from under 10-14º.
Please note these are ballpark numbers, just to give you an idea of where to start looking for your own devices.

NOTE - some DAWs require you to start playback to hear any sound generated from a plugin. Other DAWs, such as Premiere, may not let audio effects play noise themselves. In that case, we recommend tuning in another environment to find a suitable uBACCH u-BACCH angle first.
LISTENING
Start simple with obvious stereo hard panning or even a binaural recording. Tracks like Money by Pink Floyd, Lovesong by Adele, or Afro Freestyle by Erykah Badu are great starting points.
When turning uBACCH u-BACCH on and off, there should be an obvious image change: those instruments and sounds located directly at the speaker in bypass should pop out to either side, or even approach either ear. This may be less obvious on very wide stereo setups, but you will still notice an increase in depth and immersion, especially with ambience and reverb.
...
u-BACCH ideally should be the last processing on your master bus / stereo out. If you use room correction software, more often than not you still want uBACCH u-BACCH after the room correction, as many softwares such as Sonarworks alter delays and levels between left and right to create a more matched signal at the listening position. If this is before u-BACCH, it would ideally create a more symmetrical listening environment for uBACCH u-BACCH to perform in. On the other hand, if room correction is after uBACCHu-BACCH, it could alter the timing and phase within the BACCH filter and decrease performance. However, this is likely to vary depending on setup and software, so do feel free to experiment both ways!
