FM2000 Audio Processor by Vorsis

FM2000 Audio Processor

The FM2000 is modeled after the popular Vorsis AP1000 31-band audio processor and includes all of the features of the AP2000 except the HD processing chain and its dedicated digital output. The FM2000 hardware is equipped with 30% more DSP horsepower, a completely overhauled five band AGC, new voice distortion management technologies and a new, high-performance distortion managed clipper. The five band AGC now incorporates Sweet Spot Technology (SST), a Vorsis exclusive, which manages the behavior of the five band AGC in real time to ensure that it always operates within its ‘Sweet Spot’. Unlike broadband AGC algorithms of the past, SST is a completely new way to manage the five band dynamics controller to maximize the consistency of the station’s on-air presentation, no matter what the source material or audio levels from source to program source. The newly designed five band AGC also incorporates adjustable inter-band coupling to ensure a consistently set spectral balance regardless of program content.This product targets customers who seek the performance specifications of the AP2000 but do not require the HD processing chain.

“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 AP2000 and FM2000 processors perform precision peak limiting without generating the artifacts associated with peak limiters having fewer bands. Operating in very narrow frequency bands, the operation of the Fine Grain limiters goes completely unnoticed by the ear. There are absolutely no ‘swishing’ artifacts; just increased on-air loudness and a revealing of subtle program details that result in increased “listenability” of the station’s programming.

Vorsis Bass Management System

The Vorsis Bass Management System (VBMS) circumvents bass-related distortion plaguing other broadcast audio processors. It works by monitoring program energy in different parts of the audio spectrum while manipulating the behavior of the final peak limiter. The result is increased bass impact and detail 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 the VBMS algorithm.

Sweet Spot Technology

Sweet Spot Technology (SST) is embedded within the AP2000 and FM2000 processors and is responsible for managing the medium and long-term spectral behavior of the five-band AGC as program content changes. It does so by internally monitoring and then managing certain internal parameters within the multiband AGC as program elements change – something a typical broadband AGC cannot do. The result is an uncannily natural-sounding consistency in both on-air loudness and spectral balance regardless of variations in the incoming source material.

VoiceMaster

The cleanliness of announcer voice poses a challenge for broadcast audio processors when adjusted for maximum loudness. VoiceMaster addresses this by detectingvoice and then specially processing it to accurately control voice peaks prior to the main clipper. The result is absolutely pristine on-air voice regardless of how aggressively the processor may have been adjusted for music.

Smart Stereo Enhancement

Stereo Enhancement is a common feature in audio processors today. However our approach is a new technology we call Smart Stereo Enhancement. It operates in the sum and difference domain and under the management of specialized automatic level and spectral management algorithms. The result is an extremely stable ‘on-air’ stereo image that is wide, alive, exciting to listen to, and yet still natural sounding. End users have reported hearing artistically important nuances in music that were simply inaudible after being processed by competing products.
