What is Audio Fingerprint?

Audio Fingerprint — 术语表

A compact digital summary of an audio signal used to identify songs or detect duplicate content.

技术细节

In the audio processing pipeline, audio fingerprint affects how sound is captured, stored, and reproduced. Digital audio fundamentals — sample rate, bit depth, and channel count — determine the theoretical quality ceiling. The Web Audio API provides browser-native DSP (Digital Signal Processing) capabilities including gain control, filtering, spatialization, and real-time analysis. Understanding audio fingerprint is essential for optimizing audio delivery, where format choice can reduce file sizes by 70-90% with minimal perceptible quality loss.

示例

```javascript
// Audio Fingerprint: Web Audio API example
const audioCtx = new AudioContext();
const response = await fetch('audio.mp3');
const buffer = await audioCtx.decodeAudioData(await response.arrayBuffer());
const source = audioCtx.createBufferSource();
source.buffer = buffer;
source.connect(audioCtx.destination);
source.start();
```
