Spectre makes metering as beautiful as it is useful. Design, speed, accuracy and dependability are all central to Spectre’s design, placing it among the most powerful real-time analyzers in the industry. And, at a fraction of the price of most tools like it, Spectre is ideal for students and professionals alike.


Spectre is mind-blowingly powerful and stable. With this update, we’ve completely rebuilt Spectre's foundation, significantly increasing its responsiveness and performance.

Right On Target

Spectre has always been incredibly accurate, but the enhanced performance in version 1.7 makes your meters more detailed and responsive, providing an even clearer picture of your audio.

Beautiful Meters

Spectre's updated meters are now even easier to configure. Additionally, they are now Retina-ready and fully optimized for OS X Mavericks, including improved full-screen & multiple display support.

Everything in its right place

Each of Spectre's meters comes packed with customizable Meter and Trace options, allowing you to build around your own workflow and metering environments.

Best of all, they're neatly contained in popover menus, meaning Spectre keeps your workspace free of clutter and confusing menus.
