American EQ For Software Developers


BTE Audio has extended its line of Equalization Algorithms with the AEQ3, a high performance digital equalization algorithm that simulates the sound and feel of the world-renowned American Mixing Consoles of the late 1960s.
BTE Audio tell us that, with its proprietary topology, the AEQ3 algorithm simultaneously achieves both absolute sonic accuracy and extremely high processing efficiency. Targeted at desktop and embedded professional audio applications, BTE say that the AEQ3 algorithm will enable quality-conscious third-parties to incorporate the highly revered American EQ sound into their products.
AEQ3 American Console Equalizer Algorithm features ten bands which have the center frequencies 31Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz. The amount of boost or attenuation is continuously variable from -12 dB to 12 dB on all bands.
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.
Pricing and Availability:
The AEQ3 Demo (integrated into a Windows VST Plug-in) requires a WIBU Systems CodeMeter Stick and it is only available to well-established audio hardware and software manufacturers.
