VU Meter Pro vs Bounce

VU Meter Pro is a professional audio metering app for broadcast, streaming, and live sound. It combines an analog VU meter with a loudness meter, phase meter, LED bar meter, and waveform display. Arrange the meters you need on screen to match each on-site workflow. Connect any USB class-compliant device (audio interface, mixer, recorder, or the audio output of a camera or switcher) with a single USB cable and start measuring right away. Use it as a portable meter in the field, or as a fixed 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) Standards-based measurement Loudness measurement follows ITU-R BS.1770 and conforms to EBU R128 / EBU Mode (Tech 3341 and 3342) and ARIB TR-B32, at 48 and 96 kHz. Measurements are verified against reference signals. ITU-R BS.1770 is the measurement standard widely adopted by national broadcast loudness practices such as ATSC A/85 (US) and OP-59 (Australia), which target −24 LKFS. Loudness presets set the target and the True Peak limit in one tap: ARIB TR-B32, EBU R128, ATSC A/85 and OP-59 for broadcast, plus Spotify, YouTube and Apple Podcasts for streaming. Built for the field · Responsive, real-time metering · Standard and wide-range VU scales (−20 to +3 / −40 to +10) · Seven meter themes for different lighting conditions and preferences · LED bar colors: four presets, or set your own three zone colors · Peak Indicator with an adjustable True Peak threshold, so you can tell at a glance whether a peak occurred · Input Trim (±5 dB) for level calibration · Peak-hold readouts for easy reading at a glance Launch and measure. No setup required. This app is built and maintained by a working engineer in radio, audio, and video production, for use in the field. Visibility and operational reliability are the top priorities. Use with an external audio interface. The built-in microphone is not suitable for accurate measurement.

Set your iPhone or iPad next to the speaker and it listens through the microphone. Prop it on a shelf, a desk, or a nightstand. It stays awake while the music plays and lets the screen sleep when it stops. NINE WAYS TO VISUALIZE YOUR MUSIC • LED Spectrum: a rainbow spectrum analyzer, glowing segments and floating peaks that fall with gravity • Pulsar: stacked waveform ridges • VU Meter: an analog needle on a faceplate • Classic LED: the classic grid with green, yellow, and red peaks • The Grid: a 3D wireframe of frequency, time, and level with a cyan glow • Spectrogram: frequency over time, scrolling across the screen • Terrain: a moving landscape as a lit, colored surface • Color Wave: continuous bars with peak indicators • Ferrofluid: a glossy black sphere that grows spikes with the music MONO OR STEREO Spread to split the screen into left and right channels. Pinch to bring them back together. SIMPLE CONTROLS Double-tap for the mode picker, swipe to change visualizations, drag up or down for sensitivity. Press ? to see them all.
