[known examples]
some artists deliberately encode visual content into the spectrogram. this tool can't identify what those images show, but the famous cases give you a sense of what to look for:
Aphex Twin — Windowlicker (1999) — a self-portrait of Richard D. James appears in the second half of the track "Equation". image lives roughly between 8 kHz and 22 kHz.
Nine Inch Nails — Year Zero ARG (2007) — multiple tracks contained spectrogram images including a phone number, a hand, and other ARG clues.
Plaid — 3 Recurring (1999) — geometric patterns and text embedded in the high-frequency range.
Venetian Snares — Look (2005) — a photograph of a cat occupies most of the track's spectrogram.
Massive Attack — Atlas Air (2010) — encoded text appears toward the end of the track.
deliberate spectrograms tend to live in the high-frequency band (less audible, less destructive to the music) and have sharp edges that natural audio rarely produces — that's exactly what the detector keys on.
