Clip Node

Overview

Section titled “Overview”

Clip Node is an AudioWorklet-based audio node designed for high-quality buffer playback in web applications. It goes beyond the built-in AudioBufferSourceNode by offering loop crossfading, precise playhead events, fade in/out curves, and support for loading custom sounds — features commonly needed in game audio and interactive media.

Features

Section titled “Features”
  • Loop Crossfade — Seamless looping with configurable crossfade offsets using equal-power curves
  • Precise Playhead Events — Sample-accurate position callbacks for synchronizing visuals or game logic
  • Fade In / Fade Out — Configurable envelope curves for smooth audio transitions
  • Custom Sound Loading — Load and swap audio buffers at runtime
  • AudioWorklet-based — Runs on a dedicated audio thread for glitch-free playback

Use Cases

Section titled “Use Cases”
  • Game Audio — Looping background music with seamless transitions and synchronized events
  • Interactive Media — Precise audio playback tied to user interactions or animations
  • Music Applications — Buffer-based playback with professional-grade crossfading
