Free 64 Bit Metering Plugins For Measuring Level, Loudness, Correlation

a screenshot of the free HOFA 4U metering plugin in logic pro x

I’ve made a list of free 64 bit metering plugins for measuring level, loudness and correlation that could very well replace the metering tools that Logic Pro currently offers. This article was last updated on May 1st, 2016.

Free 64 Bit Metering Plugins

Level measurement plugins allow you to visually analyze your audio signal. When your mix is overcompressed and too loud, your ears will get used to that squashed sound, especially after a very long mixing session. Looking at a meter that measures loudness will help you stay objective, and can help you retain proper dynamics in your mix. So what’s been happening on the free metering plugin front lately? A lot!

Sonalksis FreeG Fader Plug-in

The Sonalksis FreeG is a master fader plugin that provides a large-format style fader with accurate metering, along with enhanced control of amplitude, phase and pan. It features Peak and RMS readouts, Pre and Post metering options, a selectable Pan-Law, and a ‘Fine’ mode for more precise calibration of the master fader.

Free Metering Plugins By HOFA

HOFA 4U Meter, Fader & MS-Pan

Auf wiedersehen Direction Mixer, guten Tag HOFA 4U Meter!

Have a look at the specs of the HOFA plugin and check out how it handles metering, panning and Mid/Side levels…

Features

  • inter-sample peak meter, plus an EBU loudness meter.
  • metering: peak, hold, EBU, LRA.
  • EBU scales: LU 9, LU 18, LUFS 9, LUFS 18.
  • EBU modes: Momentary, Short Term, Integral.
  • MS decoder. Balance Mid/Side levels in steps of 0.1 Db.
  • trims, fades and mutes.
  • stereo-mono switch.
  • innovative panorama function (see below).
  • changeable plugin window size.
  • mouse-over tooltips.
  • manual included.
  • latency-free, and supports all common sample rates.
  • parameters are automatable.

About that ‘innovative panorama’ function:

  • dragging the panning triangles you see in the picture pans the signal like Logic Pro’s Direction Mixer would. Keep in mind that this is something different than merely panning a (stereo) signal with the panpot on a Logic Pro channel strip.
  • Holding down while dragging enables panning beyond L/R.
  • Holding down ctrl or shift while dragging, enables Mid/Side panning: “Shift” enables panning width only, “ctrl” is for panning mid only.

HOFA 4U Goniometer & Korrelator

Features

  • switchable between goniometer and correlation meter
  • new type of goniometer with peak, hold and energy indicator
  • changeable plugin window size
  • manual included
  • latency-free, and supports all common sample rates.

    I use SSL X-Ism daily but unfortunately 32 bit only.  Many people also swear by Sonalksis Free-G.

      Hey D R, thanks. I couldn’t get the SSL X-Ism to work on my system. Once they make that one 64 bit I’ll add it. Thanks for the tip on the Free-G too. Cheers!

  • Juanverrett

    Can either of these be used as VU meters for gain-staging vocals?

  • http://logicblog.info danski

    Juan,
    Sure, I don’t see why not. I’d focus on getting the levels right at the source though – if your mic preamp has a meter, use that for metering first. Cheers.
