It seems like only yesterday that BTE unrolled their first PEQ algorithm, and now they're all the way up to PEQ6. Like parametric EQs of yore, the filter bands on PEQ6 are connected in parallel rather than series-cascade.

The PEQ6 algorithm works towards simulating the latest version of third generaton units in the digital domain. PEQ5, if you recall, focused on the second generation. Other than that, not too much has changed. They're almost indistinguishable, like chickens.

Fast 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 is automatically enabled at sampling frequencies below 88.2 kHz.
• Clearly and concisely implemented in pure C++: portable to any platform that is supported by a C++ compiler.
