The Shazam paper describes spectral-peak landmarks and time-offset matching; cover-song identification is a separate task that compares different versions of the same composition.
The Shazam paper describes selecting prominent peaks in a spectrogram, pairing anchor and target peaks into hashes, and indexing those hashes with a recording identifier and time position. Query matches produce candidate offsets; a consistent offset across landmarks supports an exact-recording match. CoverHunter addresses a different problem: matching different versions of the same composition using learned features, attention and alignment. Its paper reports results on SHS100K-Test and DaTacos. These tasks and methods should not be conflated. More explicitly, a Shazam-style landmark hash records two peak frequencies and the time difference between those peaks; matching many such hashes at a consistent time offset supports identifying a recording.
Extracting prominent local spectral peaks as landmarks.
Pairing an anchor peak with nearby target peaks to form an indexed hash.
Using consistent time offsets across hash matches to identify a candidate recording.
Comparing exact-recording fingerprints with CoverHunter’s learned cover-song task and reported SHS100K-Test/DaTacos evaluations.
Compare fingerprinting systems on the intended task, distinguishing exact-recording recognition from cover-song retrieval. Report query length, noise/transform conditions and evaluation data; the cited papers do not establish performance for every product or device.

Sidik jari adalah tanda akustik kental yang dirancang untuk mengidentifikasi rekaman bahkan di tengah kebisingan atau kompresi.
Ini mengidentifikasi puncak spektral, titik frekuensi waktu paling keras, yang bertahan dari kebisingan dan menjadi dasar hashnya.
The classic method pairs an anchor spectral peak with selected peaks in a local target zone to form a compact hash.
Ketika banyak hash kueri sejajar dengan referensi pada saat yang sama, mereka membentuk diagonal yang konsisten, mengonfirmasi kecocokan.
Pasangan puncak di-hash sebagai (frekuensi1, frekuensi2, delta waktu), sehingga menghasilkan landmark yang khas dan sadar posisi.
