With the release of APx500 software version 6.1, Audio Precision now offers the broadest set of rub & buzz defect detection methodologies available to speaker designers and manufacturers: Rub & Buzz, SoneTrac, High-Order Harmonic Distortion (HOHD), and Rub & Buzz Loudness. Version 6.1 also adds the Fast Sweep stimulus signal, IEC and IEEE calculation modes for harmonic distortion results, and the ability to save acquired waveforms to .wav files.

New analyzers include one year of software maintenance, licensing that instrument for APx version 7.0 when it is released, as well as any minor releases that occur between versions 6.0 and 7.0. Release 6.0 is compatible with all analyzers in the APx500 Series, however an APx KeyBox is required to run v6.0 on Legacy APx analyzers.

IMPORTANT: Beginning with version 5.0, a paid license is required to run each major release (e.g., v5.0, v6.0, etc.) of APx500 audio measurement software.
