Online Mastering Too Loud? Fix the Over-Limiting Mistakes
Published · by Loopin
If your online master feels loud but flat, the limiter is working too hard. Match the loudness, find the cause and fix it in the mix or with a calmer feel.
Match the level before you judge
A louder file wins a quick comparison every time. Use a loudness-matched A/B so you hear tone and punch, not volume. On Loopin the Original vs Mastered switch does the matching for you.
Listen to the loudest chorus. If the drums lost their front edge and the vocal sits flat, you are hearing over-limiting, not a better master.
Do the A/B with your eyes closed or the screen off. Visual meters bias you toward the louder version.
Spot the three signs
Flat: the chorus is no bigger than the verse. Crunchy: the snare or hi-hats sound clipped. Pumping: the whole mix ducks when the kick hits. Any one of them means too much gain reduction.
Check the numbers. A master at about −14 LUFS with a −1 dBTP ceiling has plenty of room. One far louder has less. See clipping vs limiting.
If you are unsure, play a track you love at the same loudness. Notice how much bigger its chorus feels than its verse; that contrast is what over-limiting removes.
Fix mistake 1: a limiter already on the mix bus
The most common cause is a hot, pre-limited mix. Remove the limiter, lower the mix bus so peaks hit about −6 dBFS, bounce again and master it free.
Mastering a pre-limited file asks the second limiter to squash an already squashed track. Read limiter on the mix bus for the full reasoning.
Bounce a new mix with the limiter off and compare the waveforms: a mix with a visible mountain range of peaks has room, and a flat brick does not.
Fix mistake 2: one peaky element
A single loud 808, snare or vocal peak makes the whole track limit harder. Turn that one element down 1–2 dB in the mix, then re-run. It is faster than any master-side fix.
If the problem is the low end, check whether the 808 clips first. Our guide to why a master sounds distorted helps you tell.
After the fix, listen again at matched loudness. If the master is now a bit quieter than before, that is fine, because dynamics are back.
Fix mistake 3: chasing the wrong feel
Punchy and Club are built to be loud (about −11 and −10 LUFS). If a quiet ballad sounds squeezed, switch to Warm or Cinematic (about −16), which leave more room.
Mistake 4 is chasing loudness at all. Streaming services turn loud tracks down, so a squashed master gains nothing. Automatic mastering also cannot rescue a mix that is the real problem.
Run the track through two feels and keep the quieter one when they are close. You can always make a calm master louder later, but you cannot unsquash a flat one.
A ten-minute repair routine
One: A/B at matched loudness and mark the worst 10 seconds. Two: bounce the mix again with no limiter, peaks near −6 dBFS. Three: turn down the one peak element. Four: re-run and compare against the last version.
If it is still squashed, switch to a calmer feel and listen again. Automatic mastering cannot fix a mix that peaks everywhere, so when two rounds do not help, go back to the mix instead of tweaking the master.
Write down the loudness of the version you liked best. Next time, aim for that number instead of the loudest one the tool can produce.
Streaming services normalize playback, so the extra dB you chase is mostly turned back down. The punch you lose is not. Re-run the repaired mix through free online mastering and compare against the squashed version at matched loudness.
Frequently asked questions
Why does my online master sound too loud?
The limiter is working too hard, often because the mix was already limited or one peak dominates. Match loudness and test again.
How do I fix an over-limited master?
Remove the limiter from the mix bus, lower peaks to about -6 dBFS, turn down the peakiest element and re-master.
Is louder mastering better for streaming?
No. Streaming services normalize playback, so a squashed loud master is turned down and still sounds flatter.
Which Loopin feel is quietest?
Cinematic, at about -16 LUFS. The default sits near -14, Punchy about -11 and Club about -10.
What true peak should I use?
About -1 dBTP, which is the ceiling on Loopin's WAV export.
How loud is too loud for a master?
If the chorus is no bigger than the verse or you hear crunch at about -9 LUFS and above with a -1 dBTP ceiling, you are likely past the point of benefit. Judge at matched loudness.
