Trinnov Audio, a pioneer in active acoustic technologies, designer and manufacturer of reference audio processors for home theaters, high-end hi-fi, professional audio and commercial cinemas, is pleased to announce the release of its latest processor software update, version 4.3.1.
This ambitious release provides multiple improvements and new features to its already acclaimed Trinnov Optimizer technology. The 4.3.1 update will be available during the third week of April, to all Altitude16 and Altitude32 units, regardless of age, and like all Altitude upgrades, at no cost.
This software upgrade brings improvements in multiple areas:
· Strengthens calibrations by improving rejection of ambient noise
· Improves delay alignment of subwoofers through Bass Management
· Enhances the Excursion Curve function and enables separate curves for each speaker
· Provides users with a set of optional predefined target curves
· Adds an option to reduce Pre-Ringing of FIR filters
· Improves the calibration of Active Crossovers
Adaptive Pre-emphasis for Calibrations
One of the issues facing accurate audio calibrations is combating the signal-to-noise ratio (technically the crest factor) inside a room. This is particularly true regarding low-frequency measurements where often inaudible noise, such as an HVAC unit or even outside traffic noise can corrupt the calibration. To correct this potential problem and achieve more robust and reliable measurements, 4.3.1 adds a new feature called Adaptive Pre-emphasis. By measuring the room’s noise floor and making rapid computational adjustments, Adaptive Pre-emphasis rejects the background noise measured during the calibration.
Excursion Curve Enhancements
The Altitude’s Excursion Curve feature determines the maximum amount of boost and cut the Optimizer is permitted to apply when correcting the amplitude response to match a target curve.
In addition to Adaptive Pre-emphasis, the new firmware offers an Adaptive Limiter Excursion Curve, which is based on the Adaptive Pre-emphasis computations. The Adaptive Limiter provides an extra level of protection against excessive correction where ambient noise is mistaken for an actual signal. Calibrators will also rejoice in knowing that the Excursion Curve is no longer applied on a global basis to all speakers and is now available on a per-speaker basis, enabling finer system tuning when needed.
