PLR stands for the Peak to Loudness Ratio of a piece of audio, sometimes referred to as the crest factor. You may have come across the “DR” measurement of the TT Meter – PLR is the same idea, but using the modern LUFS loudness unit standard.
PLR is a long-term measurement, giving you an overall value for a song, album or section of audio.

You’ll learn:
- How to calculate PLR
- Why it matters
- Why pushing PLR low won’t help with online loudness
- How to optimise the PLR of your music – and why you should
