The Phonic PAA3X Handheld Audio Analyzer from Phonic is a sound analysis tool for use in checking your audio equipment both in the studio and on location.

It provides an array of sound analysis tools, such as a 31-band and 61-band real-time spectrum analysis, an RT60, SPL and line meter, and other features such as internal generator, EQ setting program, microphone calibration, and speaker phase checking abilities. All functions and menus can be accessed through a central jog dial, leaving your other hand free to adjust audio settings. You can upload information and settings to your computer via the built-in USB interface. A microphone for measurements, a mic extension cable, a microSD card, and an AC adapter with USB cable are included.
