Orban/CRL’s Optimod 8585 digital surround audio processor features two- and five-band audio processing for surround sound broadcasting, netcasting and mastering.

Features include compression ratio controls and a look-ahead peak limiter; the company says it is suitable for mastering audio in broadcast productions, as well as productions intended for media such as DVD and Blu-Ray.

A CBS Loudness Controller controls subjective loudness and annoyance, working in two- and five-band modes. It limits subjectively perceived loudness to a broadcaster-set threshold, preventing audience irritation, according to the company.

The controller measures loudness as perceived by the average listener, then closes a feedback loop to limit loudness to a pre-set level. It controls loud commercials, the primary irritant in sound-for-picture applications. Third-generation improvements reduce annoyance better than loudness control alone, doing so without audible gain pumping. Orban says attack time is fast enough to prevent audible loudness overshoots, so the control is smooth and unobtrusive.

Optimod 8585 offers surround processing for up to 7.1 channels plus an independent 2.0 channel processor that can operate stand-alone with its own CBS Loudness Controller. Additional highlights include Orban’s PreCode technology, which manipulates the audio to minimize artifacts caused by low bit rate codecs.
