Densa Mix Analyzer – Loudness and Streaming Meter for Mac

LUFS, true peak, streaming normalisation, spectrum and stereo image, live on your master bus or for a whole mix file. Mac app, AU and VST3 plug-in.

In development · v0.1.5 · Paid app · macOS 11 or later

  • Integrated, short-term and momentary LUFS, LRA
  • True peak with oversampling, sample peak, PLR
  • What 8 streaming platforms will do to your mix
  • Streaming preview and mono check
  • Spectrum and goniometer with correlation
  • Whole-file analysis: WAV, AIFF, FLAC, MP3, OGG, M4A

Loud enough, and not too loud

Densa Mix Analyzer measures a mix the way streaming platforms and broadcasters do: integrated, short-term and momentary loudness in LUFS, loudness range, true peak, sample peak and PLR, with a 60-second short-term history drawn against the target of the platform you choose.

What streaming will do to your mix

For Spotify, Spotify Loud, Apple Music, YouTube, Tidal, Amazon Music, Deezer and SoundCloud it shows how much the platform will turn your mix down or up, what the true peak will be afterwards, and whether a peak ceiling or a limiter would step in.

Streaming preview applies that change to what you hear, so you listen to the mix as it will play there. Mono folds the output to (L+R)/2 for a compatibility check. Neither touches the measurement.

Spectrum and stereo image

  • Spectrum from 20 Hz to 20 kHz on a log scale, with peak hold and Hz/dB readout under the pointer
  • Goniometer (M/S) with momentary and overall correlation, and a warning when the mix has mono problems

Check a whole file

Drop a bounce on the window, or choose one: WAV, AIFF, FLAC, MP3, OGG or M4A. You get the whole-file integrated loudness, loudness range, true peak, PLR and correlation, the platform table, and the short-term curve across the entire track.

In your DAW or on its own

One code base builds the standalone Mac app, an AU plug-in for Logic and GarageBand, and a VST3 plug-in for Ableton Live, Cubase, Reaper and FL Studio. In a DAW, put it last on the master bus, after the limiter.

Measured, then checked

Loudness follows ITU-R BS.1770-4 and loudness range EBU Tech 3342; true peak is measured with 4× oversampling up to 48 kHz. In our tests the integrated reading stays within 0.04 LU of the pyloudnorm reference at 44.1, 48 and 96 kHz.

The meters come from the same measurement engine as Densa Studio and the Densa DSD Player‘s analysis window: the same audio gives the same numbers in all three.

Questions about Densa Mix Analyzer

How accurate is the loudness reading?

It follows ITU-R BS.1770-4, with loudness range to EBU Tech 3342. In our tests the integrated reading stays within 0.04 LU of the pyloudnorm reference at 44.1, 48 and 96 kHz.

Does it change my audio?

The measurement never does. Streaming preview and mono change only what you hear; switch them off before you export.

Which streaming platforms does it model?

Spotify, Spotify Loud, Apple Music, YouTube, Tidal, Amazon Music, Deezer and SoundCloud: the gain change, the true peak afterwards, and whether a peak ceiling or limiter steps in.

Which plug-in formats?

AU for Logic and GarageBand, VST3 for Ableton Live, Cubase, Reaper and FL Studio, plus the standalone Mac app. Put the plug-in last on the master bus.

When will it be available?

Densa Mix Analyzer is in development. The download will appear on this page when it is ready.
