WaveLock™ is a powerful patented embedded algorithm and tool suite for audio companies seeking superior voice interfacing and listening enjoyment.


It is well known that distortions in loudspeakers are the primary technical cause of poor dialogue in half and full duplex systems and is the ultimate constraint in achieving the highest quality audio output. For decades, the industry has been seeking a viable solution to this frustration.

Why WaveLock™

  • Zero BOM cost adder
  • No hardware changes required
  • Better wake word detection through less intermodulation and harmonic distortion
  • Smart amp-type thermal and mechanical protection at no added cost
  • Easy integration with firmware
  • Lower distortion enables higher output and bass extension

WaveLock™ treats the root cause, not the symptoms


    Echo canceller receives reference signal

  • approximate reference

    WaveLock™ algorithm linearizes transducer to better approximate reference signal

  • cleaner signal

    Echo canceller processes linearized direct path from acoustic output of loudspeaker

"This technology provides not only significant enhancement in lower frequencies but offers so much more—higher acoustic output, improved voice performance, and new freedom in acoustic design."

Explore WaveLock™ Features

  • WaveLock Virtual™ performs what-if analysis of distortion, efficiency and output tradeoffs
  • WaveLock Essential™ - the core of technology, a self-contained embedded algorithm that corrects for nonlinearities where required. No sensor needed.
  • Intelligent displacement monitoring to manage peak excursion
  • WaveLock Adaptive™, a self-contained nonlinear correction module using the product’s existing sensors to match parameters on a unit-by-unit basis. Ensures reliable performance despite product aging and environmental changes.
  • Precise voice coil temperature compensation and protection

WaveLock™ works with moving coil loudspeakers, communications applications like Skype, ZOOM and others, and any voice interface system like Alexa, Siri, Cortana, and Google Assistant.
