Audiolense is a speaker & room correction system, and a registered trademark of Juice Hifi. 
With Audiolense you can generate state of the art FIR filters for room correction and digital crossovers for 44.1 kHz, 48 kHz and 96 kHz sample rate for the usual 2.0 and 5.1 playback formats – and the ability to specify further playback formats.
Audiolense comes in three versions. The 2.0 version provides room correction for a conventional stereo setup. The surround version provides room correction and bass management for conventional setups from 2.0 to 7.1. The XO version provides digital crossovers (XO’s) for active systems, full setup customization, customizable sound correction including but not limited to full, partial or no correction on a per driver basis.
