How Songprint detects MusicGen
Songprint runs an ensemble of audio-forensic checks. For MusicGen, these signals carry the most weight:
Token-by-token quantization noise from neural codecs
High-frequency phase smearing
Bandwidth ceilings from training sample rates
Because MusicGen is open-source, it shows up in many white-label tools — making it a common hidden source of AI audio. Treat the score as probabilistic screening, not an absolute verdict.
