5-1 Introduction (������)


Slides for this chapter

In this section, we shall introduce four of the basic features for audio signal processing, including

  1. Volume
  2. Zero-crossing rate
  3. Pitch
  4. Timbre

These 4 features are of primary importance for audio signal processing and recognition. Hence we shall also describe how to compute these features quantitatively.
