ART (Automatic Room Tailoring)
The Aurora incorporates a ‘room correction’ system called ART (Automatic Room Tailoring),
entirely developed in-house.
At the press of a button, six ultrasonic sensors measure the distance to the surrounding
walls using ultrasound. Then, a 32-bit ARM Cortex microprocessor adjusts the output from
the driver array to precisely tailor Aurora’s performance. The effect is similar to the
adjustments made by a live sound engineer at a mixing desk when adapting sound to suit
different venues.
All the adjustments are made strictly in the analogue domain, without relying on DSP or
feedback in the manner of many other room correction systems. This enables much finer
and more accurate tailoring of the sound, reacting to room modes and reflections from
walls without attempting to ‘neutralise’ the sound in an unnatural way. Wherever the
Aurora is placed – in a large room or a smaller one, in a corner, against a wall or in free space
– it always performs at its best.
Built to be versatile
Aided by ART, the Aurora adapts to the way you want to use it. You might place it on a table
or sideboard and stream your favourite music playlists, radio stations and podcasts. You
might site it under a wall-mounted TV and connect it via Bluetooth or optical cable, thereby
delivering TV sound far better than any soundbar. Or, you might purchase a rechargeable
battery pack and attach it to the Aurora’s 12v input, so you can take it outside for a garden
party. Wherever you place it, the ART system ensures the Aurora is calibrated to perform at
its best.
