AudioAuditor review
A broad free toolkit for offline audio authenticity, metadata, and library audits.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AudioAuditor is an open-source Windows desktop application and cross-platform command-line toolkit for analyzing and managing audio libraries. It is aimed at listeners, archivists, collectors, and audio professionals who need offline checks for file authenticity, metadata quality, loudness, dynamics, and library organization. Its scope extends from technical inspection to playback, with a built-in hi-res audio player, parametric EQ, and visualizers.
The standout strength is breadth in offline auditing. AudioAuditor checks fake lossless and upsampled audio, MQA and MQA Studio, clipping, scaled clipping, fake stereo, and AI-generated-audio indicators based on metadata, byte patterns, provenance, watermarks, and audio signals. FFT spectral analysis estimates effective frequency cutoffs, while waveform, spectrogram, loudness, dynamics, phase, and channel-difference views support deeper comparisons. Batch renaming, duplicate detection, metadata stripping, playlist import, cue-sheet parsing, MusicBrainz enrichment, and exports to Excel, CSV, text, PDF, and Word make it useful beyond one-off file inspection.
The pricing model is unusually straightforward: the Free plan costs 0 and includes open-source distribution, no paid tiers, no locked features, no ads, and no accounts. Integrations connect the workflow to AcoustID, MusicBrainz, SH Labs API, and a wide range of music services, including Spotify, YouTube Music, Tidal, Qobuz, Amazon Music, Apple Music, Deezer, SoundCloud, Bandcamp, Last.fm, Libre.fm, and ListenBrainz. The main fit question is platform: the desktop application targets Windows, while CLI builds are available for Windows and Linux. Choose AudioAuditor for broad offline analysis and library auditing; choose another option if macOS desktop support or verified real-time analysis is essential.
