Commit to keeping:

The maximum short-term loudness no higher than -10 LUFS, at the loudest moments

The maximum True Peak level of your music to -1 dBTP



Wait, what ?

Don’t panic ! It’s not as bad as it sounds:



How to measure the loudness of your music

First, get hold of an LUFS loudness meter. Many highly affordable options are now available.

Make a note of:

The maximum Short-Term Loudness, at the loudest moment

The maximum True Peak level



If the values you’ve recorded meet the targets above – you’ve met the challenge !



Why these values ?

Short-term loudness of -10 LUFS is at right at the top end of the “loudness sweet spot” – in any genre. Sadly though, most modern release are crushed to much higher values. Short-Term readings of 10 or less usually mean very limited dynamics in your music, and guarantee it will be turned down on playback by all the major music streaming services.

If you’re already making Wide Dynamic Music, we still have a challenge for you !



Persuade someone else to take this challenge

Show them the resources on this site and challenge them to get involved

What’s the point ?

Well for one thing, your music will sound better.

But there’s more.

It will also have more impact on radio or TV, on YouTube, TIDAL, Spotify and other online players – and in many popular mp3 players.

Plus, accepting the Challenge is one of the best ways to raise awareness of Dynamic Range Day !
