Hello everyone, I’m interested in explore new things and trying different techniques that can perform better than Stereo. For my taste surround is not better than stereo. For years I searched for technique alternative or more evolved than Stereo.
I found it: Ambiophonics!
It’s open source, use only 2 speakers like stereo and eliminates the biggest problems and distortion caused by acoustics crosstalk.
Anyone can hear in Ambiophonics rather than in Stereo with just 2 things: one different arrangement of the 2 speakers and one audio processing of stereo signals. The algorithm needed is named RACE that states for Recursive Ambiophonics Crosstalk Eliminator and is open-source and free for any use.
Pay attention that Ambiophonics is not Ambisonic or Olofonic.
Roon has many DSP functionality. Through MUSE we can have parametric EQ, procedural EQ, volume leveling, upsampling, room correction, convolution, headphone crossfeed … but not RACE!
Years ago there was the official site www.ambiophonics.org … Now you can learn more by Wayback Machine at URL like these:

The RACE algorithm is not complex and I’m sure that any Roon user could give it a try if there was a preset on MUSE.
Why not add it?
I think that Ambiophonics had little diffusion within users and now is full extint.
But it is a good piece of technology. It is open source and free to use. It has a great technical documentation and background. It’s sure better than Stereo (and than many other Stereo alternative). Isn’t expensive. Don’t require additional hardware. It only needs a DSP processing!
In the past years, users don’t know Ambiophonics or, if they know it, they don’t give it a try because a “signal-processing” was expensive, complicated and not audiophile.
Nowaday, “signal-processing” is cheap and simple through DSP and many audiophile dogma attached to analog are broken.
Now Ambiophonics can grow in popularity and became for loudspeakers what crossfeed is for headphone.
What is missing? The RACE implemented by default on music management system like Roon.
Please ask me if you wish know more about Ambiophonics.
I have collected many link and documentation that I can share.
But on top af all, please, also you ask to implement RACE on Roon.
Thanks in advance to everybody.
