BACCH4Mac | Theoretica Applied Physics

BACCH4Mac is a bundle of four components:

Theoretica’s BACCH-dSP software
BACCH-BM binaural microphone
RME’s Babyface Pro
Webcam

It's designed to transform your Mac-based audio gear into the ultimate 3D audio playback system.

BACCH-dSP is a 3D audio powerhouse application for mixing and rendering 3D binaural audio over loudspeakers and headphones.

At the heart of BACCH-dSP is BACCH® 3D Sound, a proprietary technology developed at Princeton University that allows the listener to experience stunning virtual reality 3D imaging using only two loudspeakers.

It is the same technology that lies at the heart of Theoretica's critically acclaimed audio processor, the BACCH-SP.

The optional webcam lets you take advantage of BACCH-dSP’s advanced head-tracking for real-time dynamic sweet spot adjustment for seamless 3D audio over a wide range of listener locations.

The BACCH-BM are high-fidelity in-ear binaural microphones designed and built by Theoretica in Princeton, NJ, USA. With performance characterstics similar to Theoretica's flagship binaural microphone product, the BACCH-BM Pro, the BACCH-BM are used to generate personalized digital filters for BACCH® 3D Sound.

Simply plug the microphones into the Babyface Pro audio interface, perform a quick and easy calibration with BACCH-dSP that takes just a few seconds, and you're ready to experience BACCH® 3D Sound.

While the BACCH-BM are used for calibrating the BACCH4Mac system, they are also ideal for creating your own personalized binaural recordings. They require 48V phantom power, come with washable earbuds, and are individually equalized to generate a perfectly flat frequency response across the entire audio spectrum.

(The BACCH-BM is not inclcuded in the Intro Edition of BACCH4Mac.)

The Babyface Pro is a high-quality audio interface designed and built by RME in Germany. In BACCH4Mac, it is used to interface the BACCH-BM microphones with your Mac.

It can also be used as a digital or analog receiver. It has an optical SPDIF input (up to 192 kHz) to connect your preferred digital source (such as a digital audio streamer/server), and even has line level TRS inputs for your phono stage. Now you can experience your vinyl in breathtaking 3D.

You can choose to use the Babyface's built in D-to-A converters and connect directly to your amplifier or powered speakers, or you can connect to your own DAC via USB or TOSLINK. The Babyface Pro supports sampling rates up to 192 kHz.

* The Intro edition does not come with any hardware and produces only u-BACCH filters, which give 3D sound over loudpseakers (with no head tracking) based on the user's input of two tape measuremets of the listening geometry. u-BACCH filters come close to the performance of regular BACCH filters, which rely on acoustic measuremts using the BACCH-BM in-ear mic, if the loudspeakers are well-matched in frequency and phase.	$6,980	$5,980	$4,980	$980
