HawkEye comprises the most versatile audio measuring instruments in one toolset. It has been developed with the highest precision in mind to set a new standard in audio analyzing.

Unique features like bit-depth analysis and high-frequency monitoring offer a new window into the world of high-resolution audio recordings.

The user experience follows aviation industry guidelines for designing cockpit instruments. Therefore, HawkEye presents all information uncluttered, minimizing eyestrain over extended periods of use.

HawkEye’s main view shows all measurement instruments within a single window, yet this is only one mode of operation. To be as flexible as possible any instrument can be undocked in its own resizable window by a simple double-click, and then freely arranged on your screen!

  • Fantastic

    by Sonic Master
    I have used quite a few metering tools over the past two decades. This is the best overall in my experience...by far.
  • was trying out measuring systems for 7 years

    by PMT Studio
    I came across this other fine measuring system that made me forget about all others when CPU resources justification is a top concern such as some modern sessions require nowadays.
  • HawkEye is spectacular

    by PublicRecords
    Super precise metering. The loudness meter is the most comprehensive I've personally dealt with. The histograms are a nice addition. Only gripe is the FFT readout is a bit too twitchy and can be hard… Read More
