A VU (Volume Unit) meter is an analog-style audio level meter with a specific ballistics response: it rises and falls more slowly than a peak meter, giving a perceived loudness reading rather than instant peaks. A VU meter VST emulates this classic hardware tool inside a DAW (digital audio workstation).

For most producers, is the best free option because it combines VU, PPM, and RMS modes, allows full calibration, and runs stably on modern systems. Would you like a step-by-step guide on calibrating a VU meter to your specific audio interface output level?
