Find the perfect plugin for measuring the loudness, using the standard LUFS measure system that all the broadcast industries like film, TV etc. have used for decades.
This standard have finally also been adopted for online music and video streaming services like YouTube, Spotify, Apple Music etc.
The loudness wars are over, because of the new standard, “loudness normalisation”, which instead of normalising the peaks, looks at the average loudness level as perceived by our ears.
You want to use a loudness meter plugin that you can choose the loudness level you want to aim for, the peak levels, the short term LUFS and program LUFS (the full song).
Some loudness meters include more advanced features like stereo balance, dynamic range etc. I have made a list of what I consider are the best LUFS loudness meter plugins on the market today.
