How Loud Should a Master Be?

The honest answer is "it depends where the track is going to play" — a master built for a DJ set and a master built for a streaming playlist are optimizing for different playback conditions, not just different levels. Here's how to actually think about the target instead of chasing one universal number.

Why "louder" stopped being the goal

On a platform that normalizes playback loudness (Spotify, Apple Music, YouTube, Tidal — see What Is LUFS? for how that measurement works), turning your master up past the platform's target doesn't make it play back louder than a track mastered closer to that target. The platform just turns it down further on playback. What you do still pay for is however much dynamic range and transient impact you gave up limiting to get there — a real, permanent cost for a loudness advantage that doesn't survive normalization.

That tradeoff is exactly why this site's own mastering profiles don't all target the same loudness:

• Balanced targets -14 LUFS integrated, with a -1.0 dBTP true-peak ceiling — the lightest-touch option, preserving dynamics and tonal character rather than pushing for maximum loudness.
• Loud Electronic targets -9 LUFS integrated, same -1.0 dBTP ceiling — a genuinely louder master for electronic music contexts where more perceived loudness is the point, while still bounding how much limiter damage that costs.
• Streaming targets -14 LUFS integrated with a tighter -1.5 dBTP ceiling — the extra true-peak headroom specifically anticipates the small peak increases that can happen during a platform's own lossy transcoding, so the delivered file has margin to spare rather than sitting right at the edge.

Three different numbers for three different jobs, not one "correct" master loudness.

Streaming vs. club/DJ context

If a track's main destination is a DJ set or club system, that context typically isn't loudness-normalized the way a streaming app is — a track mastered conservatively can sit noticeably quieter in a set than tracks around it, mixed by ear against louder neighbors. That's the real argument for mastering hotter specifically for that use case, separate from any streaming target. It's a legitimate, deliberate choice for that context — not evidence that louder is universally better, and not a reason to master everything else the same way.

What to actually check, in order

1. Integrated LUFS against your intended context's rough target range, not a single number you saw once.
2. True peak, with real margin below 0 dBTP — see True Peak Explained for why sample peak alone can hide clipping risk that only shows up after conversion.
3. Dynamic range (crest factor) — two masters can hit the identical integrated LUFS while one still breathes and the other has been squashed flat to get there. The number alone doesn't tell you which one you made.

Check where your master actually sits

Analyze My Track measures your real integrated/short-term/momentary LUFS, true peak, and dynamic range — so you know exactly where a mix or master sits before you commit to a target, instead of mastering by feel and hoping.
