If the Audio node preview shows ... instead of oscillating bars, it means no audio is detected in the specified frequency range.

Understanding the Audio Node

Frequency Range Selection

The Audio node analyzes a specific frequency band and outputs its average amplitude:

Common Frequency Ranges:

• Sub-bass: 20-60 Hz (kick drum fundamentals)

• Bass: 60-250 Hz (bass guitar, kick drum)

• Low mids: 250-500 Hz (guitars, vocals)

• Mids: 500-2000 Hz (vocals, snare)

• High mids: 2000-4000 Hz (cymbals, clarity)

• Highs: 4000-20000 Hz (air, sparkle)

The green vertical lines show your selected range. Adjust min/max while watching the spectrum to target specific sounds.
