VU Meter
« Back to Glossary Index
A VU meter (Volume Unit meter) is a visual tool that shows the average loudness of an audio signal, closely matching the way humans perceive volume. Unlike peak meters, which react instantly to signal spikes, the VU meter responds more slowly and reflects the overall power of the sound (roughly RMS level).
It’s especially useful for:
- Balancing mix levels
- Keeping consistent vocal or broadcast levels
- Preserving healthy dynamics
A common reference point is to aim for 0 VU, which typically aligns with -18 dBFS in digital audio systems.
