How Spotify Will End The Loudness War

by Ian Shepherd




The game has changed – forever.

It’s no longer about sounding great on CD, it’s no longer about sounding great on the radio.

It’s about sounding great on Spotify, and this is fantastic news for anyone who loves great-sounding music, because it means the so-called “Loudness Wars” are about to become an irrelevant footnote in history.

If you live outside Europe or the US, you may not be familiar with Spotify yet, but trust me – you will be.

Spotify enables you to stream almost any music you like to your computer or mobile device, in return for simply listening to a few ads, or for a modest monthly subscription fee.

The interface is great – slick, professional and easy-to-use. The music sounds good – better than any mp3 thanks to the use of the Ogg Vorbis codec – and is available in even higher quality for subscribers. The catalogue is huge, and growing every day, and mobile users can even listen offline.

But what does this have to do with the Loudness Wars ?

The answer is:

Spotify uses “Replay Volume Normalisation” by default.

It adjusts the playback level of all songs so you don’t have to keep adjusting your volume control.

Which means that a genuine pop classic like “Billy Jean” will play at the same volume as the flat, fuzzy distorted mess that is Cheryl Cole’s new single.

And that anything off Kasabian’s latest album will play at the same volume as anything by Black Grape (say!).

Or that “In Bloom” from Nirvana’s masterpiece “Nevermind” will play back at a similar level to U2′s recent Loudness-War-casualty “Vertigo”.

Guess which ones sound better ? The modern, brickwalled, crushed-to-death clipping victims, or the lower-level, more dynamic, open, punchy, older stuff ?

You guessed it. To take that last example, Nirvana wins – by a mile. The kick kicks, the guitars bite, the whole thing rocks. Vertigo is a limp, mushy lump by comparison.

Try it yourself !

Don’t believe me ? Watch the video at the top of this post. Or fire up Spotify and check out this playlist.

If you don’t have Spotify yet, just line them up some of the songs I’ve suggested in any audio editor, using the TT Meter or a newer LUFS loudness meter to level-match them first.

Listen to the kick drums, the snares, the guitars, the bass.

(And while you’re listening, pause for a moment to think – have you ever heard anyone complain that “Nevermind” was too quiet ?!)

QED

Every track has it’s playback volume adjusted according to “ReplayGain” values which give a decent estimate of a song’s apparent volume and therefore how dynamic it is. Very dynamic material will be compressed somewhat to boost it’s average level, but almost all recent, heavily compressed and high-level material will simply be turned down a little.

Now some of you will be saying – “ReplayGain ? I’ve heard all of this before – so what’s the big deal about Spotify ?”

Easy.

Spotify is going to take over the world

Think about it – the first evening I paid my £10 subscription and installed Spotify on my iPod, I downloaded over 200 songs. 100% legally. A week later it was over a thousand. Some are old favourites, some are new experiments. None of them are things I would have bought on CD or even mp3. And as long as I pay my subscription, I can listen to them wherever and whenever I want.

Pretty soon, this is how everyone will listen to music. (Except it’ll be with a lossless codec !) Eventually nobody will own any hard copies at all, it’ll all just sit in the cloud waiting for them to call on it.

More importantly, Spotify is where everyone will listen to new music first.

And all those people listening to music for the fist time on Spotify will have volume normalisation enabled by default.

Meaning if you want your music to sound great and leap out of the speakers at you, it doesn’t need massive level, it needs great dynamics.

Game Over.


PS. Metallica aren’t on Spotify yet, but when they are, do you think they’ll still be impressed by the 3dB-crest-factor sound of “Death Magnetic” ?

Update – 2013

I originally wrote this post in 2009, and so far my prediction hasn’t come true, sadly – the Loudness War is still in full effect.

But now Apple have enabled their own replay volume normalization in iTunes Radio – and with twice as many users as Spotify already, some people are saying this will finally be the tipping point.
