Will they show the same LUFS?

They should. Both follow ITU-R BS.1770 for K-weighting, gating and integrated loudness, and revisions 4 and 5 measure stereo the same way. The same file gives the same integrated LUFS to rounding. True peak can differ by a few hundredths of a dB, because oversampling filters differ, and that's normal.

If they don't match, check the setup: the whole file or a selection, integrated or short-term, and whether one meter heard only one channel. Why two loudness meters show different LUFS covers the usual causes.

Checking a file online

Youlean also has online tools: a live sound meter for your microphone, and a file loudness meter. Both process audio in the browser. As of September 2026, Youlean's file meter shows integrated loudness for free, and loudness range and true peak need a paid plan.

Loudmeter's online analyzer shows every reading for free: integrated, short-term and momentary LUFS, true peak with each over marked on the waveform, LRA, PSR, PLR and stereo correlation. It can also play the file at the level Spotify, Apple Music, YouTube and other services will play it. The file stays in your browser.

When Youlean Loudness Meter is the better fit

  • You want the meter inside your session, on the master bus or any track, in a DAW that loads VST, AU or AAX plug-ins.
  • You work on Windows. Loudmeter's apps are for Mac, iPhone and iPad; on Windows you only get the online analyzer.
  • You deliver in 5.1, or need presets for broadcast standards such as ATSC A/85, OP-59 or ARIB TR-B32.
  • You want a free plug-in with a loudness graph right in the DAW.

When Loudmeter is the better fit

  • You want to check a finished file with nothing to install. Drop it into the online analyzer: every reading is free and nothing is uploaded.
  • You want to hear your master the way Spotify, Apple Music, YouTube and others will play it, switching between them while it plays.
  • You want to see exactly where true peak goes over: the waveform marks each over with its time.
  • You want to meter everything your Mac plays, not only the DAW: a reference in Spotify, a client's mix in the browser. LOUDMETER: Menu Bar sits in the menu bar with no plug-in to insert.
  • You want a second screen: the free iPhone and iPad app mirrors the Mac's live meters over your local Wi-Fi.

Using both

They don't exclude each other. A common setup is a plug-in on the master bus while mixing, and a file check on the bounce before release, because the bounce is what the platforms measure. Whichever meter you use, measure the exact file you upload. For the other kinds of meters, see choosing a loudness meter.
