When a track has already been mastered, its peaks are pushed to 0 dB and its dynamic range is reduced. Running it through another mastering chain is like ironing a shirt that's already pressed - at best nothing improves, at worst you burn it.

How to identify a mastered track Peaks consistently at or near 0 dB The waveform looks like a solid rectangle ("brick wall") Very low dynamic range - loud all the time Sounds "finished" and commercially loud

Warning: Double mastering causes audible distortion, pumping artifacts, reduced stereo width, and a fatiguing harshness. It's the most common mistake we see - and the easiest to avoid.

Tip: If you're a singer or rapper who received a beat from a producer, ask them for the "unmastered" or "pre-master" version. Most producers have this ready. If you can't get it, LoudCraft will detect the high peak levels and warn you - but the result is always better with an unprocessed source.

Key takeaway: If your track has already been through a limiter, go back and export the pre-master version. One pass is always better.
