Decibel review
A cross-platform meter for detailed loudness, dynamics, phase, and spectrum analysis.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Decibel is an audio metering and analysis application for sound engineers, producers, mixers, mastering engineers, and video makers. It combines real-time monitoring with offline analysis of recorded audio and video files. The tool covers loudness, dynamics, true peak, spectrum, phase, stereo, VU, and digital RMS/peak measurement. It can run as a standalone application or in AU, VST3, and AAX formats, with support for Windows, macOS, iOS, and Android display devices.
According to the vendor's pricing information, Decibel costs $149 as a one-time purchase. The published offer includes a 30-day fully featured trial, and an educational program provides approved students and teachers with a 40% discount. The listed plan includes real-time audio metering, offline file analysis, standalone and plug-in formats, and iOS and Android display support. That structure makes the purchase easier to assess before committing, while the single listed plan keeps the feature set straightforward rather than dividing core analysis across multiple paid tiers.
Its strongest fit is for workflows that need several analysis views in one tool. A LUFS meter and histogram support loudness review, while the spectrum analyzer, spectrogram, Phase Scope, stereo correlation monitoring, VU meters, and true-peak metering cover different parts of technical evaluation. Exportable reports and statistics, customizable modules and layouts, and mobile display mirroring over Wi-Fi or USB add flexibility. Decibel integrates with Pro Tools, Cubase, Logic Pro X, Ableton Live, Studio One, Luna, and Premiere Pro. Choose it for detailed cross-platform metering and offline analysis; choose another tool if you need a broader production environment or mobile devices to perform the full analysis independently.
