AirAura is de nieuwste Vorsis audio processor voor FM en FM-HD en is meest krachtige tot op heden.
Uitgerust met de Final AirAura Clipper gepatenteerde "AirAura" definitieve Clipper-technologie en met de nieuwe versie van het Sweet Spot Technology (SST)Systeem en Bass Management Systeem (VBMS) algoritmen de AirAura kan moeiteloos concurrerende luidheid wordt bereikt.
Ook de AGC heeft afzonderlijk instelbare lage en hoge inter-band koppeling algoritmen
Maar deze processor kan ook zeer dynamisch klinken dit allemaal zonder de factoren die geassocieerd worden met luistervermoeidheid.
In het " Voice" gebied blijven de stemmen duidelijk open en zonder vervorming de uitgebreide real-time audio meet-en multi-mode verwerking analyse kun je monitoren via twee schermen in breedbeeld formaat.
Tevens kun je de Airaura nu ook draadloos remoten via 802.11g verbinding.
Ook kan deze Vorsis processor kan moeiteloos tegelijk 3 remote sessie actief hebben zonder enige problemen dit in tegenstelling tot andere processors die al moeite hebben met 1 sessie

'AirAura' Distortion-Managed Final Clipper
The technology utilized in our new AirAura final peak clipper does not generate the objectionable aliasing and intermodulation distortions commonly associated with less-complex clipper technology.
Similar in certain ways to our acclaimed 31-band 'Fine Grain' limiter (a Vorsis exclusive), AirAura operates in numerous frequency bands - a necessity for its ability to discern audio from distortion. The fine-grained selectivity afforded by the many bands is the only way to truly mitigate distortion. Without it, other technologies can only make a "best guess" at separating desirable audio components from undesirable distortion products.
By analyzing the audio and the distortion products created during peak control, AirAura utilizes accepted psychoacoustic principles to control distortion products and other artifacts that a listener might find objectionable. It is highly adept at minimizing intermodulation distortion, especially close-spaced difference frequency intermodulation products in the midrange of the audio spectrum where human hearing is usually the most sensitive.
During in-field beta testing listeners commented about how smooth and open mid and high frequency content sounded when processed by our new AirAura clipper. Achieving effortless competitive loudness while remaining subjectively cleaner than their usual on-air processor was never an issue during these tests. In fact, in one top-ten market we were actually asked if we could "turn it down just a little bit."
“Fine Grain” Processing
"Fine Grain" processing overcomes the limitations of previous methods of peak limiting in on-air audio processors. Using 31 frequency bands, the AirAura final limiters (one for FM, one for HD) perform precision spectral energy control without generating the artifacts associated with peak limiters with fewer bands. Operating according to accepted principles of human psychoacoustics, the action of the Fine Grain limiters goes completely unnoticed by the ear. There are absolutely no 'swishing' artifacts; just increased on-air loudness, detail, and "listenability" of the station's programming.
Sweet Spot Technology
Sweet Spot Technology (SST) has been uniquely designed by Vorsis to manage the behavior of the multiband AGC as program content density changes, something a typical broadband AGC simply cannot do. It effortlessly handles transitions between the hyper-compressed recordings of today and those of the past that have considerably more dynamic range. SST achieves uncannily natural-sounding consistency in both on-air loudness and spectral balance regardless of density variations in the incoming source material.
Vorsis Bass Management System - v2.0
The Vorsis Bass Management System (VBMS) enhances bass impact without affecting the clarity of mid and high frequency program. In fact, bass detail and the clarity of higher frequency audio are actually enhanced by this powerful, innovative algorithm. With VBMS operating in conjunction with our 'Fine Grain' limiters, on-air bass has never sounded so good and so natural.
Smart Stereo Enhancement
Stereo enhancement is a standard feature on all Vorsis on-air processors and utilizes a new Vorsis technology; Smart Stereo Enhancement. Operating in the sum and difference domain and utilizing specialized spectral management algorithms it provides a smooth, natural, wide listening experience without triggering multipath effects. It delivers an extremely stable 'on-air' stereo image that's exciting to listen to. Users have reported hearing, for the very first time, artistically important nuances in familiar music that could not be heard when that material was processed by other on-air processors.
