Pro loudness metering on iPhone and iPad. Check any track on-device, or mirror your Mac over Wi-Fi.
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.
