D/EQ
120 Dynamics and EQ processors distributed across 16 channels of
24-bit digital audio
CEDAR Audio launches a radical new combined
Dynamics Processing and EQ package
16 May 1998: 104th AES Convention, Amsterdam.
CEDAR Audio has further enhanced its flagship CEDAR for Windows system with the addition
of D/EQ, a uniquely powerful Dynamics Processing and Equalisation package.
D/EQ offers many powerful facilities, including the unique ability to mix and match -
simultaneously - up to 120 real-time stereo reference-quality 'virtual' IIR Equalisers
and Dynamics Processors distributed across 16 channels of digital audio. Yet despite this
world-beating specification, D/EQ is remarkably simple to configure and use, with all
signal routing, metering, status monitoring and I/O control taken care of by CEDAR's
elegant Console software.
D/EQ's Equalisers offer a frequency accuracy of better than 0.1Hz, and the standard
parametric nodes (bell-curves) offer a superb Q of 100 at 50Hz. The shelving filters
are maximally flat in the pass-band and the stop-band, and offer roll-offs of up to
100dB/octave. These facilities are particularly well suited to mastering and forensic
applications, and are an excellent complement to the FIR-type EQ contained within CEDAR's
NR-3 Noise Reduction module.
Each of D/EQ's Dynamics Processors may be defined as a compressor, a limiter, a downward
expander or an upward expander, so that you can craft almost any dynamics response
individually for each of the possible 16 channels of audio. Each processor has independent
envelope, threshold, and make-up gain controls, and an 'advance/delay' feature makes it
simple to obtain more transparent processing than conventional devices or software can
offer.
The combination of Dynamics Processing and IIR EQ also allows you to tailor the dynamic
response in user-defined frequency bands, thus making this module a superb de-esser.
Almost transparent in use, D/EQ offers the highest standards of quality and flexibility,
far exceeding those of conventional signal processing units.
D/EQ runs on CEDAR's proprietary ProDSP board, up to eight of which can be installed
simultaneously in a single CEDAR for Windows system. Each board offers 24-bit
AES/EBU and SPDIF I/O, and a pair of 40-bit floating-point DSPs. A maximally configured
system offers 16 channels of real-time processing and provides a phenomenal
400Mflops of processing power. Furthermore, every board in a CEDAR
sytem will support every software package provided by the Company, so users of D/EQ
may add facilities such as broadband noise reduction, debuzzing, declicking
or decrackling at a later date.
As usual, this CEDAR product will be available immediately following its launch at
the AES Convention.
