BEQ3

British Console Equaliser Algorithm

Discrete Class AB channel amplifier modules designed for British consoles in the early 1970s are characterized by their unique sonic qualities: tight and balanced low end, wide and smooth mid range and a warm yet lustrous high end. The BEQ3 Algorithm accurately and efficiently simulates these remarkable characteristics in the digital domain with its meticulously designed topology.



Key Features


  • Extremely High Processing Efficiency.
  • Supports sampling frequencies up to 384 kHz.
  • Clickless parameter update.
  • Proprietary topology which is optimized for low latency, low noise and high dynamic range.
  • Supports both 32 bit (single precision) and 64 bit (double precision) floating-point processing.
  • Built-in reference-quality upsampling algorithm which can be enabled at sampling frequencies 44.1 kHz and 48 kHz to achieve bell shape symmetry at high frequencies.
  • Clearly and concisely implemented in pure C++: portable to any platform that is supported by a C++ compiler.

Specifications


BEQ3 British Console Equaliser Algorithm features four bands and low pass/high pass filters which have the following specifications:

  • High Pass Filter: 18dB per octave slope with five selectable cutoff frequencies: 27Hz, 47Hz, 82Hz, 150Hz and 270Hz.

  • Low Pass Filter: 18dB per octave slope with five selectable cutoff frequencies: 3.9kHz, 5.6kHz, 8.2kHz, 12kHz and 18kHz.

  • Low Frequency Shelving/Peaking: Selectable filter type: Shelving or Peaking. Five selectable center frequencies: 33Hz, 56Hz, 100Hz, 180Hz and 330Hz. The amount of boost or attenuation is continuously variable from -18 dB to 18 dB.

  • Low Mid Frequency Peaking: Selectable 'High Q' or 'Low Q'. Ten selectable center frequencies: 220Hz, 270Hz, 330Hz, 390Hz, 470Hz, 560Hz, 680Hz, 820Hz, 1000Hz and 1200Hz. The amount of boost is continuously variable from 0 dB to 18 dB with 'High Q' and from 0 dB to 12 dB with 'Low Q'. And the amount of attenuation is continuously variable from 0 dB to -18 dB with 'High Q' and from 0 dB to -12 dB with 'Low Q'.

  • High Mid Frequency Peaking: Selectable 'High Q' or 'Low Q'. Ten selectable center frequencies: 1.5kHz, 1.8kHz, 2.2kHz, 2.7kHz, 3.3kHz, 3.9kHz, 4.7kHz, 5.6kHz, 6.8kHz and 8.2kHz. The amount of boost is continuously variable from 0 dB to 18 dB with 'High Q' and from 0 dB to 12 dB with 'Low Q'. And the amount of attenuation is continuously variable from 0 dB to -18 dB with 'High Q' and from 0 dB to -12 dB with 'Low Q'.

  • High Frequency Shelving/Peaking: Selectable filter type: Shelving or Peaking. Five selectable center frequencies: 3.3kHz, 4.7kHz, 6.8kHz, 10kHz and 15kHz. The amount of boost or attenuation is continuously variable from -18 dB to 18 dB.

BEQ3 Demo


In order to demonstrate the sound and performance of the BEQ3 Algorithm, we have integrated it into a VST Plug-in which has the following system requirements:

  • Hardware:                 Intel® Pentium® 1.7 GHz and above or AMD® Athlon® 1800 and above
                                       128 MB RAM
                                       XVGA Video Card (High Color 1024x768)
                                       Low-latency Sound Card
  • Operating System:    Microsoft® Windows®
  • Software:                   VST 2.0 compliant Host Application

Please note that BEQ3 Demo requires a WIBU Systems CodeMeter Stick and it is only available to well-established audio hardware and software manufacturers.
