How Songprint detects Sonauto
Songprint runs an ensemble of audio-forensic checks. For Sonauto, these signals carry the most weight:
Autoregressive / transformer tokenization noise in the audio codec
Section-level structure regularities from prompt-conditioned generation
Soft saturation and flat dynamics typical of one-shot generation
Sonauto output is widely used in user-generated content, so it commonly shows up in YouTube and TikTok uploads. Treat the score as probabilistic screening, not an absolute verdict.
