What AudioAuditor is

AudioAuditor is an open-source toolkit for inspecting and playing audio on Linux, Windows, and self-hosted setups. It checks files for characteristics such as fake lossless audio, AI-generated audio, MQA, fake stereo, and clipping, alongside other audio properties. Support spans 35 formats across lossless, lossy, and specialty categories. Analysis options include spectrum, spectrogram, waveform, loudness, dynamics, and phase or channel-difference views; users can also compare waveforms or spectrograms in stacked, overlay, and wipe modes and work with loudness standards.

The built-in player supports native 96/192 kHz playback, a 10-band parametric EQ, spatial audio, and synced lyrics with karaoke highlighting. Listed connections include Discord Rich Presence, scrobbling to Last.fm, Libre.fm, ListenBrainz, and Maloja, plus music-service slots for Spotify, YouTube Music, Tidal, and Qobuz. Analysis takes place locally without telemetry or analytics, and optional network functions can be turned off with Offline Mode. The opt-in SH Labs AI detector is an exception: it sends the full audio file through a Cloudflare proxy to the SH Labs API and is disabled by default. AI-generated music detection is in beta, so its result is a lead rather than a final determination.

Who it suits

AudioAuditor suits audiophiles, producers, and collectors who want to inspect audio characteristics as well as play files. Its local analysis and range of comparison views are useful for workflows that prioritize offline file examination.
