Open Audio Analyzer review
A standards-based analyzer for live audio, files, DAWs and delivery checks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Open Audio Analyzer is a free, open-source application for musicians, audio engineers and mastering workflows. It covers live-audio analysis, recorded-file analysis, loudness measurement, delivery validation and reporting across Windows, macOS, Linux, iOS and Android. Its configurable canvas provides fourteen meter modules, including loudness, true peak, VU, spectrum, spectrogram, waveform, phase and dynamics views. The result is a focused tool for measuring and reviewing audio rather than producing or editing it.
Its strongest area is standards-based measurement. Open Audio Analyzer supports EBU R 128 and ITU-R BS.1770-4 loudness analysis, delivery targets with pass/fail validation, and both real-time and offline workflows. Offline analysis covers WAV, AIFF, RF64, Wave64, FLAC and MP3 files. Users can export text, JSON, CSV and PNG reports, while the command-line analyzer extends measurement into scripted workflows. For DAW work, the software provides VST3, Audio Unit and AAX plug-ins, giving its analysis views a place inside supported digital audio workstation workflows.
The product also reaches beyond a single desktop use case. A desktop session can be mirrored to a tablet over Wi-Fi, and the platform coverage includes Windows, macOS, Linux, iOS and Android. That breadth is paired with an open-source, no-charge distribution model. Open Audio Analyzer is a strong choice for users who need standards-based metering, multiple analysis views, report exports or delivery checks without a paid license. It is less suitable for anyone looking for audio editing, production tools or a broader creative suite; its role is analysis, validation and monitoring.
