Audit Your Audio with Confidence. A powerful, open-source toolkit for audio analysis and playback. Verify lossless quality, detect AI-generated tracks, and explore your library with a built-in hi-res player and advanced EQ.

Fake Lossless Detection
Identifies files that claim high quality but are actually upsampled from lower bitrate sources via FFT spectral analysis.

Spectral Analysis
4096-point Hanning-windowed FFT determines the true effective frequency ceiling of your audio with precision.

Clipping Detection
Digital clipping scan with percentage and sample-count reporting. Thorough mode detects clipping even when scaled down.

MQA Detection
Identifies MQA and MQA Studio encoded files, reports original sample rate and encoder information.

AI Audio Detection
Scans metadata, byte patterns, C2PA provenance, AI watermarks, and audio signals to detect AI-generated music. The unified AI column shows Yes / Possible / No verdicts with confidence scores, combining standard detection, SH Labs API, and experimental spectral analysis.

Rich Export
Export to Excel, CSV, Text, PDF, or Word — all matching your DataGrid layout with styled formatting.

Fake Stereo Detection
Identifies mono-duplicate and near-mono files using inter-channel correlation analysis.

Waveform & Spectrogram Compare
Compare audio files in time-domain waveform and full-resolution spectrogram. Features stacked, overlay (with pixel-level difference heatmap), and wipe modes. Ideal for verifying remasters and lossless authenticity.

Batch Tools
Batch rename with auto-rename from tags, duplicate detection, metadata stripping, playlist import, and cue sheet parsing for virtual tracks.

Search and Scrobbling
Connect with music services to discover tracks, search across platforms, and automatically scrobble your listening history.

AcoustID Fingerprinting
Identify unknown tracks by audio fingerprint via the AcoustID and MusicBrainz database. Auto-downloads fpcalc — no setup required.

Full Metadata Editor
Edit, add, or remove tags across all supported formats — ID3, Vorbis, APE, M4A. Includes a Batch Metadata GUI to enrich missing tags from MusicBrainz.

Loudness & Dynamics
Integrated LUFS/LKFS per ITU-R BS.1770, True Peak (dBTP) at 4× oversampling, Dynamic Range (DR), and Replay Gain.

Synced Lyrics & Karaoke
Multi-provider synced lyrics with word-by-word karaoke highlighting, real-time translation, and click-to-seek. Sources include LrcLib, Netease, Musixmatch, embedded tags, and local .lrc files.

Now Playing Panel
Immersive full-screen Now Playing experience with album-cover color-matched glows, customizable layout (cover, title, artist, visualizer positions), and gradient backgrounds extracted from art.

Built-in Player

A full audio player, built right in
No need to switch apps. AudioAuditor includes a complete audio player with features rivaling standalone players — including a full-screen Now Playing experience with synced lyrics.

✅ Hi-Res Audio
Native 96/192 kHz playback with automatic fallback resampling

✅ 10-Band Parametric EQ
32 Hz to 16 kHz with ±12 dB per band, soft clipping protection, built-in presets, and custom profile saving

✅ Spatial Audio
HRTF crossfeed, interaural time delay, head shadow, and early reflections

✅ Crossfade & Normalization
Configurable crossfade (1–15s) with 4 curves (Linear, Equal Power, Natural, Sequential), gapless playback, and peak-based audio normalization

✅ Shuffle, Queue & Loop
Fair Fisher-Yates shuffle, drag-and-drop queue management, and session-persistent loop modes

✅ 6 Visualizer Modes
Bars, Mirror, Particles, Circles, Scope & VU Meter at 60 FPS with independent theming

✅ System Integration
Windows media overlay support (SMTC) — now-playing info in volume OSD, media key controls, and third-party overlays

✅ Now Playing Panel
Immersive full-screen Now Playing with ColorMatch Eyedropper, 4 animated backgrounds (Snow, Rain, Leaves, Underwater), and customizable layouts

✅ Floating Mini Player
Compact player with playback controls and an independent visualizer

✅ Your Wrapped Dashboard

MP3, AAC, M4A / M4B / M4R, OGG, OPUS, WMA, MP2, MPC, AC3, AMR, SPX

Container & Specialty
DSF / DFF (DSD), MP4, MKA, WEBM, 3GP / 3G2, AU / SND

Discord Rich Presence
Shows currently playing track, artist, elapsed time, and duration progress bar. Fetches album art from Last.fm with play/pause state icons and auto-reconnection.

Multi-Service Scrobbling
Full API integration with Last.fm, Libre.fm, ListenBrainz, and Maloja. Configurable thresholds, blacklisting, and simultaneous scrobbling.
Music streaming service integrations including Spotify, Tidal, Qobuz, Apple Music, YouTube Music

6 Music Service Slots
Choose from: Spotify, YouTube Music, Tidal, Qobuz, Amazon Music, Apple Music, Deezer, SoundCloud, Bandcamp, Last.fm, or any custom URL!

🌐 Optional Network Calls
No internet activity except when you explicitly use music search, Discord RPC, Scrobbling services, or the optional SH Labs AI detection. Offline Mode disables everything with one toggle.

< Minimal Disk Usage
Only small settings files and temporary archive extractions are written to disk. Analysis data lives in memory and temp files are cleaned up automatically.

📄 Local Logging Only
All optional logs are stored safely on your machine. No remote crash reports. No usage tracking.

🤖 Zero AI Training
Nothing analyzed or played is ever used to train generative AI. Period.
