Over Limited Master? How to Spot One in 60 Seconds
Published · by Loopin
An over limited master loses snap, flattens the chorus and tires the ear. This 60-second check works on your own masters, a client’s or one from an automatic tool.
Listen to the loudest chorus first (0:00–0:15)
Skip to the biggest section and listen for the drums. If the kick has lost its front edge, if the snare is a soft pad and the hats smear, the limiter is working too hard. A good master should still let single hits stand out. Try tapping along with the snare: if you can hear each one as a separate event, the limiter has left some life in the track.
Now go back to a verse. If the chorus is only slightly louder than the verse, the dynamics have been squashed. That is the single most common sign. A verse that is quiet and a chorus that feels bigger without being much louder is what you want to hear.
Look at the waveform for a flat top (0:15–0:30)
Zoom the waveform out. A master that looks like a solid block, with every peak hitting the same line, has been pushed hard. Real transients leave spikes above the average body of the signal.
Do not rely on the picture alone. Some mixes look flat because the arrangement is dense, such as a wall of synths. Use it as a prompt to listen, not as a verdict. Then compare it with a song you trust at the same zoom level.
Check loudness against the streaming reference (0:30–0:40)
Put a free loudness meter on the track, or master it free online to compare. If the integrated reading is far hotter than about −9 LUFS, expect heavy limiting. Streaming services such as Spotify turn tracks down toward about −14 LUFS, so extra loudness is usually thrown away. Our loudness war explainer covers why.
Different genres can run hotter on purpose, such as club tracks; treat the number as a prompt, not a rule.
A/B at matched loudness (0:40–0:55)
This is the test that tells the truth. Turn the louder version down until both match, then flip between them. If the quieter one sounds clearer and punchier, the loud one has paid for loudness with detail. Loopin’s Original-vs-Mastered switch is already loudness-matched, so run the track through the free masterer and flip the switch.
If the original wins, the fix is simple: ask for the unlimited mix or export again with the limiter backed off by 2–3 dB. Then repeat the 60-second check on the new file to confirm the chorus now lifts.
Know which genres get a pass (0:55–1:00)
Club, drill and some rap run hot on purpose, and a hard kick against a clean vocal can sound right even at high loudness. The question is not how loud it is but whether the hits still hit. If they do, leave it.
If a client asks for it louder, check first whether the chorus already feels as loud as the reference at matched level. Often the answer is a better balance in the mix, not another 2 dB on the limiter. A proper A/B will show you.
Decide the fix in the last five seconds
Master clipped hard? Go back to the mix and bounce again with peaks near −6 dBFS and no limiter on the bus, then master once. If it’s a client file that arrived already limited, tell them what you hear and ask for the earlier bounce. See clipping vs limiting.
Automatic mastering can over-limit too when you pick a loud feel. Punchy (about −11 LUFS) and Club (about −10 LUFS) trade dynamics for level on purpose, so use the default (about −14 LUFS) when you want more room. Preview is free and unlimited, so keep both versions and decide after a night’s sleep.
Frequently asked questions
What does an over limited master sound like?
Flat, with weak transients, a chorus that barely lifts and quick listener fatigue.
How loud is too loud for a master?
There is no single limit, but integrated loudness well above -9 LUFS is usually heavily limited. Streaming turns tracks down toward -14 LUFS.
Can I fix an over limited master?
Not really, because the detail is gone. Go back to the pre-limiter mix, bounce with peaks near -6 dBFS and master again at a lower loudness.
Does a louder master sound better?
Only at first. At matched loudness the less limited version often sounds better.
Can automatic mastering over-limit?
Yes, if you choose a loud feel such as Punchy (about -11 LUFS) or Club (about -10 LUFS). Compare with a loudness-matched A/B and pick the lighter option when in doubt.
