Slides for this chapter
In this section, we shall introduce four of the basic features for audio signal processing, including
- Volume
- Zero-crossing rate
- Pitch
- Timbre
本章將說明最常被用於音訊處理的四項特徵：
- 音量
- 過零率
- 音高
- 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。
