Decibel
What it is
Decibel is customizable audio-metering software from Process.Audio for sound engineers and video makers. It measures loudness (LUFS), dynamics (TrueDyn), true peak, RMS, frequency content, and stereo phase in real time. For offline work, users can drag a track into the software and export measurement statistics. Its analysis views include LUFS, histogram, spectrum, spectrogram, VU, digital meter, phase scope, stereo cloud, and super meter. Decibel is available as 64-bit AU, VST3, and AAX plugins, plus a standalone version, and the product page lists compatibility with Pro Tools, Cubase, Logic Pro X, Ableton, Studio One, and Luna. Premiere Pro is listed as compatible; DaVinci Resolve and Final Cut Pro are described as coming soon. Unlimited iOS and Android displays can connect over Wi-Fi or USB for real-time metering. The product page lists a 30-day trial, iLok authorization, and a price from $149. Licenses are described as perpetual with free updates and no subscriptions.
