## 3.1 System Overview

The overall architecture of the proposed system is illustrated in Fig. 3.1. In the backend implements the main algorithm - Audio Fingeprinting (AF), which consists of two phase: the fingerprinting stage, and the searching stage; in the frontend creates the web-based interactive interface for the system, which is user-friendly for annotation duties. We would describes more details in the subsections.

## 3.1.1 Audio Fingerprinting
The main principle for Audio Fingerprinting (AF) is query the target audio snippet from the audio dataset. As shown in Fig. 3.2, the upper flow illustrates the fingerprinting technique, and the below indicates the searching mechanism.


## 3.1.2 User Interface

## 3.1.0
所建議系統的總體架構如圖3.1所示。 在後端實現了主要算法-音頻指紋（AF），該算法包括兩個階段：指紋階段和搜索階段。 在前端中，為系統創建了基於Web的交互式用戶界面。 我們將在小節中討論更多詳細信息。
