VU Meter for Google Chrome™ is a real-time audio metering extension for Chrome tab audio. It displays VU, peak, loudness, true peak, LRA, and phase information in a compact meter interface.

It is useful for live stream monitoring, online video review, web audio testing, music playback checks, and general audio quality control. Frame mode keeps the meter visible inside the browser window while the source page continues playing. Side Panel mode is useful when you want the meter integrated into the Chrome workspace. Window mode is useful when you want to place the meter freely on another part of the screen. The horizontal layout provides a compact monitoring view for Frame and Window use, while the vertical layout offers a more traditional meter display. Output mute, mono monitoring, Side monitoring, and L/R SOLO options make it easier to check broadcast, streaming, and monitoring conditions without changing the source content.
