As you may have heard, Spotify have lowered their target playback level to the equivalent of -14 LUFS integrated.
Why are they doing this?
The major platforms have been doing this for a while now. Spotify just recently reduced their playback level from -11 LUFS integrated to -14. Meaning they simply turned down their target level by 3dB / 3LU.
The reason they are doing this is for user experience. One of the number one complaints from users is inconsistencies in volume. Loudness management works to remedy this.
What does this mean to me?
Many will have you believe that this means that you have to match it. They will tell you that you must master to that level for the best possible result.
This is misguided advice.
And worse still, it completely defeats the purpose of the platforms implementing loudness management in the first place!
So how does it work?
When a master gets submitted to them, Spotify analyses the relative loudness of the song and simply turns it up or down to match their target playback level.
Here’s a practical example:
Let’s say I master a song to -10 LUFS integrated.
Spotify’s target playback level is -14 LUFS integrated.
1 LU is the equivalent of 1 dB. So they turn down my master by 4dB.
That’s it! No damage done. All they did was simply turn it down like you would using a fader or a volume control.
The platforms that do this are generally quite coy about how and what number they target. However curious and enthusiastic engineers the world over have measured the output of the respective platforms and shared that information online.
This is great. But as always, people take these things way too literally, and before you know it everyone is talking about creating separate masters for each platform.
Unfortunately though, this mindset completely defeats the point of loudness management. Worse still, it’s forcing people down a path where they make decisions based on some arbitrary number as opposed to the merit of the audio itself.
So do I ignore it?
No. You don’t ignore it. You just make yourself aware of it.
If anything, you should take this information as permission to do what’s best for the mix.
For example, let’s say you master something to around -9 LUFS integrated, with a true peak ceiling of -1.0 dBTP, and it sounds great…
It will sound great no matter what platforms choose to turn it up or turn it down.
Conversely, back in the CD days, it was common practice to master something beyond its potential just to compete. The problem now is that those songs are being turned down by the platforms. What was a loud song yesteryear is now just an over-compressed one. If it still sounds great, that means it was the right loudness and dynamics for the song. Often it was not.
So how do I know what the right loudness for the song is?
The loudness potential (AKA the loudness sweet-spot) is when you push the master to the point just before you degrade the quality of it. The view is always best at the edge of the cliff, but too far and you fall off (paraphrased from an Ian Shepherd quote). That sounds simple enough, but it’s not that easy to find unless you know how.
Here are just a couple of ways to go about it.
Method 1: Using a constant-gain limiter
I use Slate Digital FG-X. It’s my go-to ‘volume limiter’ for when I’m raising the loudness of the mix to my mastering level. It has a big gain dial bang in the middle of it and it pretty much always does what I expect it to do.
So is it as simple as that?
No. No because when we turn something up, we are always of the impression that it sounds better. Louder usually equals better to our ears even if it isn’t. That’s why it’s important when we are mastering to remove the bias for louder and thus make an objective judgement on our processing.
Fortunately (for me at least) Slate FG-X makes this really easy to do via a feature called Constant Gain Monitoring. Simply turn on Constant Gain Monitoring and increase the gain until you hear distortion. Now you’re pretty much at the loudness potential of the mix (assuming the EQ has already been balanced). Go there, back off a bit, turn off constant gain, and and now the mix will now play back at it’s loudness sweet-spot.
Method 2: Loudness matching the master against the mix
The following process allows you to make a fair A/B comparison between your master and the untouched mix.
In your DAW, create a new track (separate from the one with my mastering processing on). Then go back to your mastering track and pull the fader down until the loudness of the master matches that of the (unmastered) mix.
Once they’re matched in loudness, flick between the two during playback and make an objective judgement about your work.
If this seems a bit laborious, there are also some great tools on the market to make things easier. Tools such as Ian Shepherd’s Perception Plugin.
Now back to the numbers!
Please don’t take this advice as ignore the numbers, but more as don’t prioritise them.
I often check the numbers after printing the first master. I do this offline using Orban Loudness Meter.
Why do I check them? Just to make sure I am not way off.
For example, if it came in at -20 LUFS integrated, I would look to see if I could increase that number a bit, but only if the material allowed me to. If it doesn’t want to go higher, I generally won’t push it.
This of course is rare in popular music.
Once again, I must stress that this is all assuming a balanced mix with balanced EQ. If those things aren’t where they need to be, then the loudness potential will already be low. Mastering is knowing when that is or is not the case.
