    • Iyo Fourier chete inoshandura isina kuyera
    • MIDI mafaira
  7. What do the MFCCs summarize after the discrete cosine transform?
    • The original waveform sample by sample
    • A compact representation of the log mel-spectrum’s broad shape

  8. What information is lost when a signal is summarized by a small set of MFCCs?
    • The recording’s entire duration
    • Every estimate of average loudness
    • Fine spectral detail and phase information
    • The existence of a time axis
