UltiMeter (M4L) Free

Ultimeter is the perfect combination of a utility device (including mid/side features) and a metering one (with correlation and LUFS metering), with a nice floating window (full version only), that you can use on a daily basis for all kinds of purposes, especially avoiding using channel settings for automation.

Here is a features list:

• Stereo to Mid/Side encoding-decoding (to feed plugins not able to do mid side processing, only stereo) 
• Separate Left/Right and Mid/Side gains and Mute
• Left/Right swap
• Phase revert for Left or Right
• Overall width control (between full mid and full side)
• Stereo pan
• Balance and Correlation graphic display
• Integrated/Gated/Short Term/Momentary LUFS display
• RMS display
• True Peak Meter display
• Floating window with same fatures + graphical level history display with configurable duration & colors (only on Full version)
