LOUDMETER: LUFS Meter
Loudness analyzer & live meter
Free
LOUDMETER brings loudness analysis to your iPhone and iPad. Check a finished bounce wherever you are, or use your device as a second screen for your Mac’s live meters.
ANALYZE AUDIO FILES
Open or drop an MP3, WAV, AIFF, FLAC, or M4A file to see:
• Integrated LUFS, plus Short-Term and Momentary maxima
• True Peak in dBTP, with an over count
• Loudness Range and Peak to Loudness Ratio
• Stereo correlation and a loudness timeline
• Reference targets for Spotify, Apple Music, YouTube, Netflix, and EBU R128
Copy your measurements or export a PNG report. All analysis runs on your device.
MIRROR YOUR MAC
Connect to LOUDMETER running on a Mac on the same local network. View live measurements on your phone or tablet and reset the Mac’s meters remotely.
The connection uses Bonjour. Only measurement and visualization data are transmitted, never your audio.
BUILT FOR MIXING AND MASTERING
Loudness measurement is based on ITU-R BS.1770-5 and EBU R128, with K-weighting adapted to each file’s sample rate.
PRIVATE BY DESIGN
No account, tracking, or analytics. Audio processing stays on your device, and live readings stay on your local network.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Thanks for your feedback, keep it coming. In this update:
• Live now shows the same detailed graph as your Mac (requires LOUDMETER for Mac 1.8.3).
• My target: your Mac's personal LUFS target appears in the target strip, ready to switch on or off.
• A steadier Live view that rides out Wi-Fi hiccups instead of pausing.
• A smoother correlation curve with a clearer fill. It stays readable when the phone is turned sideways.
• File results fill the screen in landscape with a new two-column layout on iPhone and iPad.
• Much faster file measurement, with identical results.
• Small design polish across the graph and correlation cards.
