CODA AUDIO SPACE HUB Immersive Processor

Preliminary Information

Explore SPACE SPACE is the next-generation object based immersive audio, where sound objects can be placed and moved in 3D space to enable new emotional experiences unlike anything heard before. Hearing all fine details with incredible clarity, exactly as they are, you are now not only watching, you are inside of what happens around you.

True Immersive Experience means Perfect Timing in the complete audio chain. Basically immersive sound means positioning and moving of audio objects in 3D space and this happens in the time domain.

Humans perceive the direction of sound by comparing the arrival time of transients at the two ears, therefore perfect timing in the entire audio chain is the most essential part for creating a true immersive experience.

While electronics usually provides precise transient response the time-domain characteristics of the loudspeakers are the most critical part. CODA Audio phase-linear loudspeakers are an essential part of the SPACE Immersive System Solution. The principal advantages of phase linear loudspeakers become even more important in multichannel 3D audio. Ensuring phase accuracy with no differences in timing between the various loudspeakers the essential timing information is transmitted to the listener with perfect phase coherency and transient accuracy.

Linear phase response (with DS-FIR filters) purple: N-RAY, white: N-APS

Conventional, minimal–phase loudspeakers have principally nonlinear phase response.

That means that even if they all have linear frequency response they will not match together in the time domain when used in a multichannel set up (especially with different loudspeaker types). The phase error related to the lack of time coherence will destroy the perceived localisation providing a lot of blur and smearing and be unable to produce accurate spatial image.

N-APS / N-RAY minimal phase response without phase correction.

Down (purple): Nearby identical, linear frequency responses of N-RAY and N-APS without phase correction (using IIR filters).

Up (white): The summation of N-APS + N-RAY in minimal-phase mode without phase correction providing irregular summation with deep cancelations caused by their uneven phase responses.

Even if N-RAY and N-APS are the same family loudspeakers with similar size, identical cone drivers, and tuning their phase responses are different and require time correction to be able to work together.

White: N-APS Minimal-Phase response without time correction – typical phase behaviour of a 2-way loudspeaker. purple: N-RAY Minimal-Phase response without time correction – typical phase behaviour of a 3-way loudspeaker.

Conclusion. In a multi-channel immersive system the phase response of every loudspeaker must be 0° to ensure time coherence, improved localisation of sound sources and spatial stability. That enchanted immersive impression is not achievable with conventional speakers.

Next Dimension Space The True Immersive Experience SPACE HUB is a 19”/3U state of the art immersive processor that features highly advanced spatial audio algorithms for positioning and movement of sound objects. Up to 128 audio sources can be rendered into 128 outputs to create an ultimate 3D immersive listening experience in theaters, musicals, HOW, live venues, concerts and production studios. SPACE HUB is an integral part of SPACE Immersive System Solution.

The SPACE HUB Control application provides a reliable control and monitoring of the SPACE HUB processor. It is optimised for both MacOS and Windows, for both tablet and native interfaces. Available plugins (VST3, AU, AAX and AAX-DSP) for automation and control improve the production workflow.

The dreams come true.

For artists, producers and engineers SPACE opens up new possibilities to take the audience inside their story in the most authentic and emotional way.

Loudspeaker set up.

Object based audio production is not limited to a specific speaker setup, it can be reproduced using diverse configurations from 9 up to 128 loudspeakers to allow great flexibility.

System Design System Optimiser Design all sizes of audio system from the smallest of gatherings right up to the largest of stadium productions with incredible ease.

Creating proposals for clients. SPL Pressure mapping is presented to you in incredible detail, with a strong sense of reality. Pushed for time.

Workflow is tantamount to accuracy and with this in mind, bespoke tools are provided to fully enable the system designer.

Accuracy Computationally intensive operations have been highly optimised to deliver results in seconds, not minutes – call it ‘mathemagic’…

Predictions are wholly based on real-world electro-acoustic measurements, heavily utilising multifaceted multipole expansions. A highly complex atmospheric model is employed; taking temperature, dewpoint, humidity and altitude into account. Complex response functions are morphed using cutting edge continuous phase techniques, the end result being authentic free-field predictions indistinguishable from reality.

Power Clever tools are included to create complex designs effortlessly.

Use the layout tool to place loudspeakers in a multitude of shapes and arrangements. The template engine is an incredibly powerful way of managing entities within the layout system.

Measurement microphones can be placed anywhere within the 3D scene. Probes are a smart extension of the measurement microphones that make choosing line array angles stress-free.

Link Groups define how line arrays are connected, and allow electronic filters to be applied to correct for distance and splay angle.
