How Streaming Platforms Process Your Audio (And What to Do About It)

You've finished your mix. It sounds great in your DAW, great on your monitors, great on your headphones. Then you upload it to Spotify or Apple Music and something feels off — quieter, duller, or just different to how it sounded before.

This is not your imagination. Streaming platforms process your audio after you upload it, and if you don't account for that during mixing and mastering, the results can be unpredictable.

What streaming platforms actually do

Every major streaming platform uses a process called loudness normalisation. The goal is to create a consistent listening experience across all tracks — so a quiet ambient record doesn't suddenly sound tiny next to a heavily compressed pop track.

To do this, platforms measure the loudness of your track using a standard called LUFS (Loudness Units relative to Full Scale) and adjust the playback volume to hit a target level. Spotify targets around -14 LUFS. Apple Music targets -16 LUFS. Tidal and YouTube have their own targets too.

If your master is louder than the platform's target, it gets turned down. If it's quieter, some platforms will turn it up — though most leave quiet tracks alone rather than boost them.

Why this matters for your master

The problem isn't the normalisation itself — it's what happens to heavily limited masters when they get turned down.

If you've pushed your master very loud through limiting, you've likely sacrificed some dynamic range and transient detail in the process. When the platform turns that master down to -14 LUFS, you end up with a quieter version of an over-limited track. The dynamics are still gone, but now the loudness advantage is too.

A master that hits -14 LUFS naturally, with good dynamics intact, will often sound better on streaming than one that was pushed to -8 LUFS and normalised down.

What to do about it

Master to the platform targets, not against them. Aiming for around -14 LUFS integrated is a sensible target for most electronic music on Spotify. This gives you a master that sounds consistent across platforms without unnecessary limiting.

Check your master with a loudness meter before delivery. Most DAWs have one built in, and free tools like Youlean Loudness Meter make it straightforward to measure your integrated LUFS before export.

Export at the highest quality your distributor accepts. Most platforms accept 24-bit WAV files. There is no benefit to exporting at a lower bit depth or sample rate than your session.

Listen on the platform after upload. Don't assume it will sound the same as your local file. Stream it on different devices — phone speakers, earbuds, a Bluetooth speaker — and check that it translates the way you intended.

The bottom line

Streaming platforms are not neutral. They have their own loudness targets, their own encoding processes, and their own playback behaviour. Understanding how they handle your audio means you can make better decisions during mastering and avoid unpleasant surprises after release.

If you're unsure whether your master is ready for streaming, that's exactly what a mastering session is for.
