I’ve not been following this closely so I apologize if this has already been posted. If not I thought it would be of interest here.
Unless I’ve missed the mark, this audiocheck.net test demonstrates what I believe BAACH aims to address.
Regardless, this test is one of many the site offers in a unique toolbox that is quickly helping me troubleshoot short comings in my setup and my own limitations.

The Audiocheck site is great. Spending a few dollars to support the site is worth it given how all the tracks available for download can help.

Thanks for the info. Re the MOTU… “MK2” was a PS Audio typo on my part. I meant to type, “MK5”. The MOTU UltraLite MK5 does indeed have USB in.
It could be timing issue for the request. MUNICH high end is this weekend

It was a few months ago. Everything is in boxes now and waiting for a few more projects to be completed before I can get a chance to get the stereo set up again.

Say I were to introduce Dirac Live to see if improves sound, would BACCH take care of that in addition to the imaging tool?
Still having a blast with BACCH4MAC INTRO, just received our Decware ZROCK 2 … another great addition to our system.
Has anybody been able to do a direct comparison between the INTRO and the AUDIOPHILE and or +?
Thanks,
Steve

Only thing I can say my BACCH DSP transform function sounds different having filter’s calculated to my room and its acoustic changes or between my head and ears and someone else’s. The difference is easily discernible on FR frequency Response and Cross talk cancellation curves and through listening to the different filters created for different people or acoustic panel locations or configurations.
So it boils down how close your room interactions and head and ears match the baseline that ships with the software version.

I did not know about this. I like the price! I like the try it free option! I am going to try it in my computer lab. Thanks for posting this!!

Edgar told me last night that this isn’t a product for you and me, it is a license for manufacturers to add simple BACCH processing to their products. I am so confused about this. I have to guess he knows what he is talking about.

After 48 grueling hours without my BACCH-SP (my choice) it is finally back in the system. Whew! I missed it so much!

Very nice choice! What is Felix’s Dark Days Exit, say track 2 Miss Teardrop or track 4 Falling off a Horse, like in BACCH? Another fine choice would be 5 Squeeze the Trigger from Deaf Safari.
In the queue for a late night listen, thanks!
Anything Felix does sounds splendid. But those are standouts indeed!
New Infrared tracker on order replacing my camera that doesn’t work unless lamp is on in listening room
BACCH-dSP 13
Dear BACCH-dSP user,
Theoretica Applied Physics is pleased to release version 13 of its industry-leading spatial audio application, BACCH-dSP. As described in more details in the Release Notes at the bottom of this message, this new version includes new features and many improvements to all editions (Intro, Audiophile, Audiophile+, and Pro) of BACCH-dSP.
In particular the head tracking functionality (available in the Audiophile edition and above) has been further improved and allows the use of a low-cost infrared camera for head tracking in pitch darkness, without the need of installing software drivers.
BACCH-dSP can run under the latest Mac OS, Ventura 13.4, as well as all previous Mas OS versions down to Mojave 10.13. Please do not update to a version of Mac OS past the present latest version (Ventura 13.4), before you hear from us confirming that BACCH-dSP is compatible with that Mac OS.
Please note that head tracking now works only under the Ventura and Monterey Mac OS (12.x and 13.x) , so if your Mac is running under the Big Sur Mac OS (11.x) or an earlier OS, and you wish to use the head tracking functionality (Audiophile edition and above), you would need to update your Mac OS to at least Monterey (12.x) or preferably to the latest version, Ventura 13.4 before updating BACCH-dSP to version 13.
Please follow the instructions below to update the BACCH-dSP application on your computer. Please choose Option A if you are updating from version 12.1.5 or above, or Option B if you are updating from a version prior to 12.1.5. Option A will not overwrite your existing BACCH or change your existing BACCH-dSP settings.

RELEASE NOTES for v 13.0.1 _________________ _______________________________
-
Head Tracking has been further improved with increased robustness in dim lighting conditions.(Audiophile Edition and above)
-
The use of the Intel RealSense depth camera for head tracking in darkness, introduced in v 12.0.3 of BACCH-dSP, is no longer possible under Mac OS Monterey (12.x) and Ventura (!3.x) due to Intel not releasing the required drivers. Consequently, BACCH-dSP 13 introduces a new IR webcam functionality for head tracking in darkness: simply plug this low-cost infrared camera (which you can purchase directly from Amazon.com, or other suppliers,) or a similar IR webcam, in your Mac instead of the regular webcam, and select “webcam” from the HT Sensor. (Audiophile Edition and above)
-
Webcam Resolution can now be selected from a toggle bar under sensor control sub-panel (upper right corner of the Advanced Settings panel). We recommend leaving this setting in the default “1280” position unless high resolutions are really needed. (Please note that changing the resolution will require remaking head-tracked BACCH filters with the new resolution setting.) . (Audiophile Edition and above)
-
The low frequency resolution of the frequency response plot has been raised significantly. The plotted response below 80 Hz on that plot is now an accurate representation of the actual response.(Audiophile Edition and above)
-
Fixed a bug that caused the feedback detection system to be triggered when the Arm button is activated in systems where TotalMix was altered to allow phono stage input. (Audiophile Edition and above)
-
The “By Ear” mode for designing u-BACCH filters (most relevant in the Intro Edition of BACCH-dSP) has been significantly improved. When the ”Left Image” or “Right Image” buttons (which appear when the “By Ear” mode is selected in the u-BACCH designer interface, after clicking the Arm button) are clicked, a new test signal is emitted for “By Ear” manual selection of the best u-BACCH filter. This new test signal is a specially designed pink noise signal, that is band-passed and HRTF-filtered in such a way that It allows a more precise spatial perception of the u-BACCH-rendered source in 3D space. The object of the u-BACCH design in this mode, is to simply vary the Speaker Span Half-Angle setting (using the large green vernier dial, or directly in the numerical value in the Speaker Span Half-Angle field) so that the pink noise source is perceived to be located as close to 9:00 o’clock, when the ”Left Image” button is selected, or 3:00 o’clock, when the ”Left Image” button is selected. . (Intro Edition and above)
-
Added a “Free All Channels” button at the bottom of the Audio Settings sub-panel that allows freeing all input channels that they are all available In the 3DM mixer, including the channels that were assigned for mic input (typically channels 1 & 2) and loopback input. This setting is typically useful only when using the 3DM mixer (Pro Edition only) and carries the risk of causing feedback if there are live mics on the channels routed by the 3DM mixer to speakers in the same room as the mics (hence the alert window that comes up when this setting is selected, which warns of such a danger). (All editions)
-
Reduced CPU load by making many processes, including audio processing, more efficient. (All editions)
-
Various enhancements to the Graphical User Interface. (All Editions)
-
Various minor bug fixes and enhancements to functionality and stability. (All Editions)
