Web Audio Api

The Web Audio API skill enables AI agents to generate, process, and analyze audio directly within the browser using JavaScript. It provides low-latency access to hardware audio devices for tasks like synthesizing sounds, applying effects, or analyzing frequency data without external libraries.

When to use it

• Creating interactive soundscapes for web-based games or educational apps.
• Implementing real-time voice modulation or audio effects in live streaming tools.
• Analyzing audio input for beat detection or pitch recognition features.
• Generating synthetic speech or musical tones programmatically.

Key capabilities

• Synthesize audio using oscillators and noise buffers.
• Apply dynamic effects like reverb, delay, and distortion via nodes.
• Analyze frequency data using the AnalyserNode for visualizations.
• Connect audio sources and destinations with a flexible node graph.
• Control playback timing and volume precisely in real-time.

Example prompts

• "Create a simple synthesizer that plays a C-major chord when a button is clicked."
• "Analyze the frequency spectrum of user microphone input and display it as a bar chart."
• "Add a reverb effect to audio played from a file before sending it to the speakers."

Tips & gotchas

Ensure your AI agent runs in a secure context (HTTPS) as browser security policies often block audio contexts on insecure origins. Initialize the AudioContext only after a user interaction, such as a click, since browsers require explicit user gestures to start audio processing.
