Auro Technologies launches the Auro-3D® Authoring Tools V2.0

Mol, 12 March 2014 – Auro Technologies officially launches the updated Auro-3D® Authoring tools – now integrating the Auro-Codec® Encoder for a simple and flexible solution to create native 3D audio.

The Auro-3D® format is the next step in sound evolution, and now you can get your hands on the tools to create immersive 3D audio content. The Auro-3D® Authoring Tools allow you to add immersive 3D sound to your existing workflow, whilst making the 3D content available through a single file distribution, and played back in digital cinema, or home theatre via Blu-ray™.

Audio reproduction has evolved from a point source (Mono), to a single dimension (Stereo), to two-dimensional Surround sound (5.1/7.1). To produce true three-dimensional sound, a reproduction system must include a vertical Z-axis (top-to-bottom), in addition to the existing X (side-to-side) and Y (front-to-back) planar axes found in current systems. Auro-3D®’s three-layered approach (Lower, Height, and Top Layers) completes this evolution by creating a realistic three-dimensional soundscape, and the new integrated Auro-3D® Authoring Tools allows content creators to work flexibly and efficiently across all of these dimensions in sound.

The tools

Auro-3D Mixing Engine

The Auro-3D® Authoring Tools consist of a set of plug-ins which now includes 3D panning and mixing with support for all Auro-3D® formats and various Surround formats, as well as encoding with the Auro-Codec®. A basic Auro-3D® session consists of the Auro-Panner, Auro-Bus, Auro-Mixing Engine, and Auro-Return plug-ins. Each plug-in is inserted on its own DAW audio track and connects to the A3DHost processor. The Auro-Panner sends its track’s audio to a selected Auro-Bus, which routes the signals to one or more Auro-Mixing Engines. The Auro-Mixing Engine lets you set Auro-3D® and downmix configuration settings, mixes the audio, and then sends it back to the DAW using the Auro-Return plug-ins for monitoring and bouncing of the mix. It also contains the Auro-Codec® Encoder to immediately output the encoded deliverable.

This set of plugins is designed to be easily integrated into any existing content-creation workflow, while solving many technical limitations present in DAW stations, such as limited bus widths and the lack of 3D panning. All tools allow the creative to work within the uncompressed audio domain, and multiple masters (in different formats) can be mixed at the same time. Combined with the Auro-Matic™ Pro upmixing plug-in, this makes the full Auro-3D® Creative Tool Suite the most flexible and most efficient solution on the market for the creation of 3D immersive sound.
