Tomoaki Shimizu
VU Meter is a professional metering app for broadcast, streaming, and live sound. It features a VU meter along with a loudness meter, phase meter, LED bar meter, and waveform display. Lay out the meters you need on screen to suit each on-site workflow. Connect any USB class-compliant device for instant measurement. Mixers, recorders, cameras, switchers — connect with a single USB cable. Use it as a portable meter for remote broadcasts and field production, or as a dedicated tool in the studio. Works on both iPhone and iPad. What it measures: · Audio level (analog VU meter / LED bar) · Loudness (Momentary / Short-term / Integrated / True Peak / LRA) · Loudness history (graph display up to 24 hours) · Waveform (Waveform Scope, up to 30-minute history, pinch-to-zoom) · Phase (Lissajous + correlation meter) Launch and measure. No setup required. This app was built by a working engineer in radio, audio, and video production — for use in the field. Designed with visibility and operational reliability as the top priorities. Use with an external audio interface. The built-in microphone is not suitable for accurate measurement.
