Sonnox Oxford SuprEsser now AAX compatible

Sonnox has announced the availability of the Oxford SuprEsser in Avid’s AAX format. Managing Director, Rod Densham comments, “This marks a major milestone in a formidable two-year AAX project. Producers and engineers who have been waiting for full AAX compatibility can now continue working with our top of the line Elite Bundle in Pro Tools 11.


The Oxford SuprEsser is both a very highly-featured professional De-Esser and a Dynamic EQ. There is a simple mode for quick fixes, but also an advanced mode for increased functionality and fine-tuning. The combination of an intuitive FFT display and three listen modes enables the user to easily see and hear exactly where the problem frequencies are, allowing the rapid reduction or removal of the offending audio. As well as being able to trigger the full band compression, only the offending frequencies can be carefully carved out. Since the SuprEsser can operate at all frequencies, ‘plosives’ and other annoyances can also be removed effortlessly, making it more than a simple De-Esser. Additional features include Automatic Level Tracking, Linear Phase Filtering and a Wet/Dry blend control for final balancing.

    Porting our plug-ins for AAX is a complex and time-consuming task, because we feel strongly about respecting and preserving the integrity of the original Oxford plug-ins, which have become a worldwide standard in modern audio production,Densham continues. “With the January 2014 introduction of the SuprEsser AAX, we have completed the final component of the Sonnox Elite Bundle, which we consider the Ultimate Oxford Plug-in collection.”

    AAX development continues with our Sonnox Restore Suite and Fraunhofer Pro-Codec plug-ins due for release in the first half of 2014. We remain committed to developing the best sounding, most useful and user-friendly plug-ins possible.” Densham concludes. “The development of a number of totally new products is now a primary goal of our expanded design team.
