Accuwave's SSA Studio is a free companion app for SPL meters and voltmeters. Specifically designed for Accuwave's APM-2 and APM-X SPL meters and AVM-X Smart Voltmeter, this app enables you to record Basscam videos, display real-time dB SPL, compute average SPL measurements, and share them with your friends. It also comes with a dual-sensor competition mode and voltmeter events and notifications.

However, it's important to note that SSA Studio is not compatible with the APM-1. Overall, Accuwave's SSA Studio is a useful tool for those who own Accuwave's SPL meters and voltmeters, providing a seamless experience for measuring and recording sound and voltage levels.
