BTE Audio releases AEQ1 American Console Equalizer Algorithm
With their symmetrical curves and smooth proportional Q characteristics, the secret ingredient of the legendary LA sound is the discrete channel equalizer modules designed in the late 1960s.
The AEQ1 Algorithm accurately and efficiently simulates the earlier version of these modules in the digital domain with its meticulously designed topology.
AEQ1 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.
There seems to be a demo VST plug-in of AEQ1 (which requires a WIBU Systems CodeMeter Stick), but I couldn’t find a link on the BTE page, so perhaps you need to email them for more info.
