Spotify loudness: do you need a mastered track for streaming, and what LUFS actually means

6 October 2026 · ~6 min read

Short answer: yes, you need a mastered track for streaming, but not a loud one. Spotify, Apple Music and YouTube all turn tracks up or down to a target loudness before anyone hears them, so a master crushed to be loud gets turned down to the same level as a master with space in it, and keeps all its distortion. Spotify's own guidance is to aim for about -14 LUFS integrated and keep true peaks under -1 dBTP, or under -2 dBTP if your master is louder than that. What mastering gives you on streaming is not volume; it is a track that translates from earphones to a car to a phone speaker, with a ceiling that the platform's encoder does not clip.

What the platforms actually do

Every major streaming service normalises playback. Spotify measures each track and album and plays them back at around -14 LUFS by default. Apple Music's Sound Check works to a slightly quieter target. YouTube sits close to Spotify. The exact numbers move a little year to year, and listeners can switch the feature off, but the shape of it has been stable for years: if your master is louder than the target it is turned down, and if it is quieter it is turned up only as far as its own peaks allow. That last clause is the one that catches people. A quiet master with peaks near zero cannot be turned up without clipping, so it stays quiet next to the playlist.

What LUFS means, in a sentence each

• Integrated LUFS is the loudness of the whole track, start to finish, on a scale where -14 is quieter than -8. It is the number the platforms read.
• Short-term LUFS is the loudness of the last few seconds, which is useful while mixing a chorus and useless for a streaming target.
• True peak, in dBTP, is the highest point the waveform reaches once it is reconstructed as analogue, which is higher than the sample peak your DAW shows. The lossy encode pushes it higher again, which is why the ceiling is set below zero.
• Dynamic range, loosely, is the gap between the loud parts and the quiet parts. Normalisation preserves it; brickwall limiting destroys it.

Why loud masters sound worse on streaming, not better

Ten years ago the loudest track in a playlist won, because nothing turned it down. Now it loses twice. The platform turns it down to the target, so it sits at the same level as the track beside it, and every bit of limiter distortion that was added to make it loud is still there at the quieter level, where the ear hears it as a flat, tiring sound. A drill track mastered with its transients intact at -12 LUFS will sound harder than the same track crushed to -7, because the kick still hits after normalisation and the crushed one's kick was flattened to make room for loudness nobody gets to hear.

What a streaming master needs

1. A good mix first. Mastering cannot fix a buried vocal or a muddy low end, and a loud master makes both more obvious.
2. Headroom on the mix. Send the stereo file with the peaks around -6 dBFS and no limiter on the master bus, so the mastering stage has room to work.
3. A loudness target chosen on purpose. For most independent rap, drill and pop releases somewhere between -14 and -10 LUFS integrated is the range, with the genre and the track deciding where. Louder than -10 is a choice to pay for in distortion.
4. A true-peak ceiling of -1 dBTP, or -2 if the master is on the loud side, so the encode does not clip.
5. One master for every platform. The service that offers you a Spotify master and an Apple master is selling the same file twice.

How to check your own master

Put a LUFS meter on the master bus and play the whole track through, because the integrated reading only means something over the full length. Read the integrated figure and the true peak. Then do the test no meter replaces: play it after a released track you admire, with both at the same level, on a phone speaker and in a car. If yours sounds smaller or flatter, the problem is the mix or the limiting, not the number. I cover the difference between mixing and mastering, and what to send for each, in the mixing and mastering guide, and the service itself is on the mixing and mastering page.

Questions I get asked

What LUFS should I master to for Spotify? Around -14 LUFS integrated is Spotify's own suggestion, with true peaks under -1 dBTP. If you go louder, keep peaks under -2 dBTP, because the turn-down and the lossy encode both add distortion to a hot master.

Does Spotify turn quiet tracks up? Only when the listener's loud mode is on, and only up to the headroom the master leaves. By default a quiet master stays quieter than its neighbours, so a master that is far under -14 can sound small next to the playlist.

Do I need separate masters for each platform? No. One master at a sensible loudness with a true-peak ceiling works on all of them. Different masters per platform is a service some people sell and nobody needs.

Is louder better on streaming? Not any more. Once the platform normalises, a track crushed to -6 LUFS is turned down to the same level as one at -14 and keeps all its distortion. Dynamics survive normalisation; loudness does not.

Can I check loudness myself? Yes. Any free LUFS meter on the master bus, playing the whole track from start to finish, gives the integrated reading. The true-peak figure is on the same meter.
