Bacch Dsp, True stereo?

@emergingsoul  Crosstalk is the reason we aren’t fooled into believing that we are not in a live environment. Hearing content coming from the right speaker with your right ear is expected and the time it takes to travel across your face to your left ear locates that sound in space. The same thing is happening with the left ear. This is why super directional speakers like horns can create a magical image due to almost eliminating crosstalk but the place that this magic happens is very small and usually only works for one person and perhaps one more directly behind them. I’ve personally experienced this. BACCH does this digitally in real time with audio queues in the music. As @asctim above notes it isn’t a manufacture equipment issue, the only way to address it on that end is with a hyper directional system as I described or a software based solution like BACCH. You also noted people aren’t interested in this, perhaps you missed my post. I literally built my entire system around Dr. Choueiri’s research and this is the last and most exciting piece I want to add to my system. I don’t believe it is a complicated issue, just a difficult one to address which is why Dr. Choueiri has spent so many years working on a solution.

Very encouraging comments.

So the system is designed for a highly focused Target of one person to achieve results. So group of people probably wouldn't benefit as much.

How come you haven't gotten the system you seem very happy about what it does despite the challenges to implement?

There won’t be any challenges to implement it in my system because it is entirely active and it will be plug and play. The only challenge is money, like many things. I did feel it was important to get the room corrected and have the highest level of DSP processing possible before implementing BACCH. Thus my recent purchase of the dspNexus, which is now processing 8 channels with 12 biquad filters at 192K in real time, the results are stunning. The largest impact in sound reproduction is the speakers, next is the room, and I would say crosstalk is third in my list so it will be my next purchase when I can afford it. It’s really quite simple to implement from my discussions with their team. It simply is added between your source and the speakers and works its magic by using head tracking technology. The initial set up includes using microphones put in your ears to measure your unique ears and head and then it’s set up and you don’t need to do anything else. I’m not sure why you perceive that to be difficult. Much less difficult than measuring the room and developing biquads for my DSP in my opinion.

I agree that highly directional speakers do certainly help with stereo imaging, but I couldn’t get them to do much in terms of crosstalk elimination. I’m using horn speakers right now in conjunction with crosstalk reduction and I’m getting very good results. I heard some big horns at this summer’s Pacific Audiofest that had the best stereo separation of anything at the show in my opinion. Others mentioned it too. Besides inter-aural crosstalk, early side wall reflections can seriously degrade the stereo presentation too, and it is truly amazing how good a standard 2 speaker system without crosstalk reduction can be at producing a wide, spacious sound field with clear separation between instruments when early reflections are properly addressed, either through directional speakers, room treatments, or a combination of both. With crosstalk reduction it can be even more amazing, but dealing with early reflections remains super important, otherwise the full benefits won’t come through. Horns or other directional speakers can make that easier. I’ve also found that the quality of the speakers and other components remains as important as ever. If the tonality is off or there is too much distortion, the sense of realistic space is severely compromised, although you can almost always still hear some benefit. Even when listening to my laptop speakers I can get some sense of spaciousness with crosstalk reduction that would otherwise not happen at all.

Bacch uses microphones in your ears to measure the room and your ears to get the best sound.

I didn't know about this. I wish there was a video giving a full scale view of what you need to do to install this thing.  For some reason they just don't wanna do this.

I have a basic dac streamer connected to a pre-amplifier which is connected to the amplifiers which is connected to the speakers.

Do I need to get a desktop computer integrated to use this thing?
