Audio Input

Captures live audio and outputs it as a signal you can patch into anything. Three modes give you different ways to read the audio: overall loudness, frequency spectrum, or raw waveform shape.

Inputs

Outputs

Controls

• Mode: Loudness (single level value), Spectrum (frequency-band energy), or Waveform (raw audio shape).
• Channel: Which audio input channel to capture.
• Fall: Envelope decay time in seconds for Loudness and Spectrum modes. Short values snap to transients; longer values smooth them out.

Ideas

• Waveform into Parametric Curve Y + Phasor into From Polar: projects the audio waveform onto a circle, creating a reactive ring that pulses with the music.
• Spectrum mode into a Color node's hue: low frequencies shift toward red, highs toward blue. Frequency-reactive color in one patch.
• Loudness into any shape's scale: bass-pumping geometry that grows on every kick.

Tips

• In Spectrum mode, the Freq Low and Freq High inputs define the frequency band. Narrow the range to isolate kicks (20–200 Hz) or hats (8000–16000 Hz).
• Waveform mode samples the audio buffer per-point across the frame, so you get the actual wave shape as a varying signal.
• Gain applies before output. Use it to boost quiet sources or tame loud ones.
