SPL HawkEye

Visualize Your Mixes
SPL HawkEye includes a versatile set of audio measurement instruments. Access a Level Meter, Loudness Meter, Bit Monitor, Vector Scope, and Spectrum Analyzer. Unique features like bit-depth analysis and high-frequency monitoring offer a new window into the world of high-resolution audio recordings.

Hit Target Levels and Fix Mix Issues
Monitor your mixes with the Level Meter to ensure you leave enough headroom; avoid distortion when your music is uploaded to Spotify, iTunes, and TIDAL. Target specific integrated loudness levels using the Loudness Meter to prevent your tracks from being reduced in level or increased in level—and limited—by streaming services. Reveal problems in digital signals related to bit usage, depth, distribution, and DC offset. Identify phase-related issues that suck the life out of your mixes using the Vector Scope and pinpoint problematic resonances with the Spectrum Analyzer.

Clean and Flexible GUI
The graphical user interface (GUI) follows aviation industry guidelines for designing cockpit instruments. HawkEye presents all information uncluttered, minimizing eye strain over extended periods of use. HawkEye’s main view shows all measurement instruments within a single window. Any instrument can also be undocked and used within its own resizable window by double-clicking on it, allowing you to reposition the instrument to best fit your screen.

  After years of using free meters, I decided to invest in Hawkeye and it has been well worth it. The information is clear and helpful to get your mix exactly where you want it.

  Although it's a useful single screen… Read More
