BACCH-dSP is a standalone 3D audio powerhouse application for mixing/production and rendering of 3D binaural audio through loudspeakers and headphones.BACCH-dSP is the heart and brain of Theoretica's BACCH4Mac packages.
It is the most advanced binaural audio processing tool available today. It incorporates many techniques, algorithms, and methods that have only recently evolved out of the research laboratory, and allows for the construction and rendering of stereo 3D audio images with breathtaking realism.
It is the result of 4 years of continuous development by Professor Edgar Choueiri, President of Theoretica Applied Physics and Director of Princeton University’s 3D Audio and Applied Acoustics Laboratory.
BACCH-dSP can be easily configured as a parallel processor for the leading DAW applications (e.g. ProTools, Logic Pro, Ableton Live, etc.) or as a standalone application for processing audio from audio files, and audio from audio file players (Roon, iTunes, JRiver, etc...) and streaming services (Tidal, Spotify, etc...).
The wide functionality of the BACCH-dSP includes the following main features:
A main feature of BACCH-dSP is BACCH 3D Sound, which is an advanced patented crosstalk cancellation technology, developed at Princeton University, that yields vivid and accurate 3D imaging from binaural (and regular stereo) audio over loudspeakers. This is the same technology at the heart of Theoretica’s highly acclaimed high-end audio processor, the BACCH-SP.
Unlike other crosstalk cancellation technologies, BACCH® 3D Sound produces no tonal distortion and can be individualized to the listener’s head and ear shape, the particular response of the loudspeakers and the loudspeakers/listening configuration through a quick and easy calibration using the in-ear BACCH-BM binaural microphone.
3D audio through loudspeakers is no longer confined to a tight listening sweet spot. BACCH-dSP’s state-of-the-art head-tracking technology assures real-time dynamic sweet spot adjustment for seamless 3D audio over a wide range of listener locations.
The advanced panel of BACCH-dSP allows further tailoring and optimization of the resulting BACCH filters
The BACCH-dSP is the first product to use the newly developed BACCH-hp headphones technology, which resulted from a 4-year research project at Princeton University.
BACCH-hp filters, produced easily with the BACCH-dSP application, allow binaural audio to be reproduced through headphones with the following main features:
A central feature of BACCH-dSP is its powerful and intuitive 3D mixer: BACCH-3dm.
BACCH-3dm produces vivid and realistic binaural mixes (equivalent to binaural recordings produced through dummy heads or humans with in-ear microphones) from a collection of multiple audio sources such as the tracks of a multi-track recording.
BACCH-3dm’s visually striking graphical interface allows positioning multiple sound sources (each corresponding to a bus line from your DAW, a microphone signal, an audio file or a track from a multi-track file) precisely in 3D space. BACCH-3dm has the following additional features:
The powerful BACCH-hoa module allows for up-to-fourth-order High-Order-Ambisonics-to-binaural rendering and 3D sound-field navigation using up to 20-speaker full dodecahedron virtual speaker system (in BACCH-3dm) and individualized HRTFs.
The BACCH-hoa module has the following main features:
Starting with version 6.0, BACCH-dSP includes the new u-BACCH module (which is the sole module in the BACCH4Mac Intro Edition). The u-BACCH module (where the “u” stands for universal) produces u-BACCH filters, which give 3D sound over loudpseakers (with no head tracking) based on the user's input of quick tape measuremets of the listening geometry.
u-BACCH filters come close to the performance of regular BACCH filters (the latter rely on acoustic measuremts using the BACCH-BM in-ear mic) if the loudspeakers are well-matched in frequency and phase.
The u-BACCH module has the following features:
This new module, fisrt introduced in BACCH-dSP 8.0, allows binaural content creators (e.g. mixing engineers, musicians, composers, AR/VR audio designers) to easily and intuitively design/draw complex trajectories in 3D space for the sources in the 3D mixer to follow.
The 3D Trajectory Designer module has the following main features:
