4. What happens to a CQT pitch pattern when a chord is transposed up one octave?
   • It becomes a single DC component
   • Its bins shift by a different amount at each note
   • It becomes identical in absolute bin locations without shifting
   • It shifts upward by one octave’s fixed number of frequency bins

6. How does the documented librosa CQT implementation compute the transform?
   • By computing each filter from scratch with no shared processing
   • With a recursive subsampling method
   • By recording the audio twice
   • By ignoring all low frequencies
7. What does a chroma-CQT representation do with bins from different octaves?
   • It discards all pitch information
   • It converts audio into RGB images
   • It folds them into pitch classes
   • It assigns each bin a speaker identity
8. What does one column of a time-frequency CQT matrix typically represent?
   • A complete MIDI score
   • A 3D camera pose
   • A single global loudness score for the whole recording
   • CQT coefficients across frequency bins for one analysis frame in time
