  1. Chii chaizvo chinonzi 'kutanga' muodhiyo?
    • Iyo nguva iyo acoustic chiitiko chinotanga, senge kurwisa kwenoti
    • Kupera kwezwi
    • Avhareji yeruzha rwenzira
    • Kupera kwerwiyo
  2. What does spectral flux measure for onset detection?
    • A rule that marks every beat as a note onset
    • Positive increases in spectral energy between successive frames
    • A decay detector that selects only falling energy
    • A pitch estimator that finds the nearest MIDI note
  3. Sei hafu-wave rectification ichishandiswa mu spectral flux?
    • Kuwedzera kuora
    • Kushandura odhiyo kuita mavara
    • Saka chete kusimuka (kwakanaka) shanduko yesimba inobatsira, kufuratira kuora
    • Kudzikamisa audio
  4. Ndeupi rudzi rwekutanga rwakanyanya kuoma kuona?
    • Ngoma inopinza yakarira
    • Makwakwakwa esimbi ane ruzha
    • Musungo wekurova
    • Violin yakapfava, zvishoma nezvishoma inozvimba
  5. Chii chinodzivirira nhanho yenhonga yepamusoro ine chikumbaridzo?
    • Zvinokonzera kaviri uye zvenhema kutanga
    • Audio compression
    • Kuchinja kwepitch
    • Stereo kuwedzera
  6. What can a neural onset detector learn from labeled audio examples?
    • A guarantee that every onset will be detected
    • Patterns in the audio features that signal event beginnings
    • A fixed tempo that applies to every recording
    • The identity of every instrument without evaluation
  7. What does onset backtracking do when detected times are used to create audio slices?
    • Moves each onset to the end of the entire recording
    • Replaces each onset with the nearest musical beat
    • Moves an onset to the nearest preceding local minimum of an energy signal
    • Adds a fixed one-second delay after every peak
  8. What can happen when an onset model is transferred to a different instrument or dataset?
    • Its predictions are guaranteed to remain identical
    • The audio automatically becomes monophonic
    • The model no longer needs a time-frequency input
    • Its performance may change and should be evaluated in the new domain
