Delay
Audio Delay Effect
An effect that records and plays back audio after a set time interval, creating echo and rhythmic repetitions.
Technical Detail
In the audio processing pipeline, delay 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 delay is essential for optimizing audio delivery, where format choice can reduce file sizes by 70-90% with minimal perceptible quality loss.
Example
```javascript
// Delay: 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();
```
