Supports analog (passive and active) as well as digital filter (FIR and IIR) design.

: Following the passing of Chris Strahm, official technical support ceased. While still valued for its accuracy, many modern designers have transitioned to newer tools like Successor Projects

The "5" in its name signifies a massive leap forward from previous versions, introducing a modernized Windows interface, significantly faster solve engines, and the integration of the LPM (Loudspeaker Parameter Measurement) module—allowing designers to import real-world driver data directly into the simulation environment.

The Leap 5 operates via the Linearx Leap software. The software integration is deep, controlling the hardware’s gain staging, signal generation (sine sweep, pink noise, stepped sine), and data capture.

The integrated crossover module allows passive and active filter design up to any order. Users can simulate component tolerances, impedance equalization, and phase alignment across multiple drivers.
