Reverb
Reverberation
The persistence of sound in a space after the original sound stops, simulated digitally for spatial effects.
Chi tiết kỹ thuật
In the audio processing pipeline, reverb 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 reverb is essential for optimizing audio delivery, where format choice can reduce file sizes by 70-90% with minimal perceptible quality loss.
Ví dụ
```javascript
// Reverb: 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();
```
