What is Audio Nodes?
Audio Nodes is a node-based editor for building simple audio graphs in your browser. You create small building blocks (nodes) like oscillators, effects, and sequencers, then connect them to define signal flow.
Core Concepts
- Nodes: Functional blocks (e.g., Oscillator, Reverb, Sequencer, Synth, Speaker).
- Inputs/Outputs: Nodes expose inputs and outputs for audio or MIDI. Connect compatible types.
- Connections: Drag from a node’s handle to another node’s matching handle to create an edge.
- Parameters: Each node has tunable controls. Adjust values to change how it behaves.
Quick Start
- Add a node from the library (left panel). Try an Oscillator and a Speaker.
- Connect the Oscillator’s Audio Out to the Speaker’s Audio In.
- Click “Start Audio” if prompted. Adjust oscillator waveform and frequency.
- Add a Reverb between Oscillator and Speaker for ambience.
- Try MIDI: Add a Sequencer → Synth → Speaker chain and press Play on the Sequencer.
Tips
- Use the “?” button on each node for a quick description of inputs/outputs.
- Zoom/pan with trackpad or mouse; drag nodes by their body (UI controls won’t interfere).
- Save/Load your project in the left panel. Default project loads on first visit.
- Web MIDI works in secure contexts (https). If denied, allow MIDI access in your browser.
