Majibu na maelezo huonekana unapojibu maswali.

  1. Je, ni matokeo gani ya mfumo wa utambuzi wa chord ya sauti?
    • Mpangilio uliopangwa kwa wakati wa lebo za chord
    • Orodha ya maandishi ya nyimbo
    • Saizi ya faili ya rekodi
    • Picha ya bendi
  2. Ni kipengele gani ambacho ni muhimu zaidi katika utambuzi wa chord?
    • Tarehe ya kurekebisha faili
    • Chroma (darasa la lami) vekta
    • Idadi ya vituo vya stereo
    • Bitrate
  3. Kwa nini utengano wa sauti-percussive mara nyingi hutumika kabla ya utambuzi wa chord?
    • Ili kufanya wimbo usikike zaidi
    • Ili kutafsiri maandishi
    • Ili kukandamiza kelele ya ngoma ambayo inaficha maelewano
    • Ili kufupisha wimbo
  4. Je! Miundo ya Markov iliyofichwa ilichukua jukumu gani kitamaduni katika utambuzi wa chord?
    • Inazalisha mchoro wa albamu
    • Kukandamiza sauti
    • Kurekebisha gitaa
    • Mifuatano ya chord laini kwa kutumia mipito inayowezekana
  5. What can small tuning differences do to chroma-based chord recognition?
    • Shift energy between nearby pitch bins and confuse closely related chord labels
    • Remove all temporal information from the recording
    • Make every chord label equally likely
    • Convert chroma features into text tokens
  6. Ni programu gani ambayo ni mfano maarufu wa utambuzi wa chord kwa wanafunzi?
    • Programu ya lahajedwali
    • Chordify
    • Programu ya hali ya hewa
    • Kifuatiliaji cha ndege
  7. Which two processes does Chordify identify in placing chord labels on a song?
    • Speaker diarization and voice activity detection
    • Source separation and image captioning
    • Chord recognition and beat tracking
    • Pitch correction and text-to-speech
  8. How did Lee and Slaney create supervised training labels for their HMM chord-recognition method?
    • They used only unlabelled live recordings
    • They transcribed lyrics and inferred chords from word sentiment
    • They used random labels and optimized without audio
    • They generated labels by harmonic analysis of symbolic music and paired them with audio rendered from the same symbolic data
