5-1 Introduction (蝪∩?)

[chinese][english]

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

本章將說明最常被用於音訊處理的四項特徵:

  1. 音量
  2. 過零率
  3. 音高
  4. 音色

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

這四項語音特徵常被用於語音訊號處理與辨識,因此我們也會說明如何以可運行的程式碼來進行這些特徵的計算。
