Kediska Aqoonsiga Heesta Dabool

Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

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. Waa maxay astaanta chroma (HPCP) u taagan tahay?
   • Heerka decibel ee saxda ah ee ilbiriqsi kasta
   • 12-kii fasal ee garoonnada oo leh octave ayaa wada burburay
   • Magacyada fanaaniinta bandhiga
   • The file’s compression format
3. Sidee bay nidaamyada u maareeyaan daboolka lagu duubay fure muusig oo kale?
   • Way quusteen oo ma soo sheegaan wax ciyaar ah
   • Waxay u beddelaan codka qoraal
   • Si meerto ah ayay u wareegaan 12-bin chroma vector si ay u tijaabiyaan meel-ka-baxyada oo dhan
   • Waxay dedejiyaan duubista ilaa 2x
4. Farsamo noocee ah ayaa fidiya hal isku xigxig oo maqal ah si uu ula jaanqaado mid kale oo leh waqti ka duwan?
   • JPEG cadaadis
   • Isku shaandhaynta random
   • isdhexgalka Pixel
   • Wakhtiga firfircoonida leh (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
