Quiz ngir xàmmee way cover

Sooy def quiz bi, tontu yi ak leeral yi dañuy feeñ.

1. Why can a recording fingerprint designed for near-identical audio fail on a cover performance?
   • A cover may change tempo, key, arrangement, and instrumentation while preserving the composition
   • It is guaranteed to match any recording with the same title
   • Every cover uses the same waveform samples
   • It can identify a song only from album artwork
2. Luy màndarga chroma (HPCP)?
   • Niveau decibel bi ci seconde bu nekk
   • classe pitch yi ak octave yi bokk dajaloo
   • Tur waykat yiy jouer
   • The file’s compression format
3. Nan lay def ba sistem yi mëna jëfandikoo cover buñ enregistre ci beneen tombu musical?
   • Dañu xàddi ba noppi wax ni amul benn match
   • Dañuy soppi audio bi ci mbind
   • Dañuy wëlbati vecteur chroma bi am 12 bin ngir saytu bépp toxal
   • Dañuy gaaw enregistrement bi ba 2x
4. Ban pexe mooy tàllal benn audio ngir méngale ko ak beneen bu am tempo bu wuute?
   • kompresioŋ JPEG
   • mélangage aléatoire
   • interpolaasioŋ pixel
   • Deformasioŋ dynamique de temps (DTW)
5. How can a learned cover-song model support retrieval across tracks of different lengths?
   • Map each track to a fixed-dimensional representation and compare representations
   • Require every version to have the same waveform length
   • Search only by file name
   • Compare the full waveform sample-by-sample without alignment
6. Which training loss does ByteCover use to compact same-composition versions in its embedding space?
   • A reconstruction loss only
   • Triplet loss, alongside a classification loss
   • A binary cross-entropy loss between raw waveforms
   • A next-token prediction loss
7. How can chroma features help compare some cover recordings?
   • They make every instrument produce identical features
   • They remove all effects of arrangement and production
   • They summarize pitch-class structure and reduce sensitivity to octave and some timbral changes
   • They prove two tracks are the same composition
8. What information can a single global chroma summary lose when comparing cover songs?
   • The fact that pitch classes repeat across octaves
   • The recording’s file extension
   • Whether the waveform has a left and right channel
   • The temporal order of pitch-class events through the track
