BTE Audio releases PEQ3 Program Equalizer algorithm      10/04/08
Mid 1990s EQ Sound


BTE Audio has extended its line of Equalization Algorithms with the PEQ3, a high performance digital equalization algorithm that simulates the sound and feel of the extremely rare program equalizers of the mid 1990s. Looks like one half of a Nightpro EQ3D to us.
They tell us that, with its proprietary topology, the PEQ3 algorithm simultaneously achieves both absolute sonic accuracy and extremely high processing efficiency. Targeted at desktop and embedded professional audio applications, BTE Audio say that the PEQ3 algorithm will enable quality-conscious third-parties to incorporate the highly revered modern program equalizer sound into their products.
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.
  • Clearly and concisely implemented in pure C++: portable to any platform that is supported by a C++ compiler.
PEQ3 Program Equalizer Algorithm features six bands. The first four peaking bands have the center frequencies 10 Hz (SUB), 40 Hz, 160 Hz and 650 Hz. Each band is 2.5 octaves wide. The fifth high frequency shelving band has a cutoff frequency of 2.5 kHz. The sixth "air" band is a -boost only- high frequency shelf with five selectable cutoff frequencies: 2.5 kHz, 5 kHz, 10 kHz, 20 kHz and 40 kHz. The amount of boost or attenuation is continuously variable from -15 dB to 15 dB on all bands except the air band which has an amount of boost that is continuously variable from 0 dB to 20 dB.
Pricing and Availability:
The PEQ3 Demo requires a WIBU Systems CodeMeter Stick and it is only available to well-established audio hardware and software manufacturers More information:
