Free MusicGen (Meta AI) Detector
Detect Meta's MusicGen tracks. Open-source AI music detection. Free, instant, all model sizes supported.
What is MusicGen (Meta)?
MusicGen (Meta) (by Meta AI, launched June 2023) is a leading AI music generation platform supporting versions small, medium, large, melody. It produces full songs from text prompts, including vocals, instrumentation, and arrangement. Since its release, millions of tracks have flooded streaming platforms — raising the need for reliable detection.
How AI Song Checker detects MusicGen tracks
Our ASC v8.3 engine combines 82+ forensic audio signals with a Bayesian inference scoring system specifically tuned for MusicGen's output characteristics:
MusicGen-specific signature: MusicGen uses a transformer with discrete audio tokens (EnCodec). This leaves a distinct neural codec artifact band between 5-8 kHz. The output sample rate of 32 kHz with upscaling to 44.1 kHz creates resampling artifacts. Group delay deviation is uniformly low — a tell-tale sign of token-based generation.
Unique detection capabilities for MusicGen
- EnCodec neural codec artifact detection
- Token-boundary discontinuity analysis
- MusicGen melody-conditioned vs unconditioned distinction
- Open-source community fingerprint database
Why use a dedicated MusicGen detector?
Generic AI detectors often fall short on MusicGen because each AI music engine has distinct mathematical fingerprints. AI Song Checker tunes its detection model specifically for MusicGen's architecture, giving you a 99.3% accuracy rate with only 0.3% false positives — far better than one-size-fits-all tools.
Who needs MusicGen detection?
- Record labels & A&R screening submissions for human originality
- Streaming platforms (Spotify, Apple Music, Deezer, YouTube Music) implementing AI content labeling per the EU AI Act 2026
- Music journalists & curators verifying authenticity before featuring tracks
- Independent musicians protecting their work from AI-generated imitations
- Music supervisors (film, TV, ads) avoiding AI tracks in licensing deals
- Sync agencies & libraries maintaining catalog integrity
How to use the MusicGen detector
Three steps, under 10 seconds:
- Upload any audio file (MP3, WAV, FLAC, OGG, M4A — up to 50 MB) or paste a YouTube/Spotify/SoundCloud URL.
- Analyze — feature extraction happens locally in your browser via Web Audio API. Only numerical features are sent to our secure scoring server.
- Get the verdict — an AI probability score from 0% to 100%, plus platform attribution.

Frequently Asked Questions about MusicGen Detection
Is the MusicGen detector free?
Yes — 3 free analyses per day.
Which MusicGen variants?
All: small, medium, large, and melody-conditioned.
Does it work for community fine-tunes?
Yes. The EnCodec neural codec leaves distinctive artifacts regardless of fine-tuning. ~96% on community variants.
Accuracy?
99.3% on Meta's released models, 0.3% FPR.
Can MusicGen evade detection?
Heavy post-processing can reduce accuracy. We recalibrate weekly.
