LUFS Converter Pro normalizes in two steps – first it measures, then it adjusts. That produces a measurable result, not a rough guess. You can see the values in the log and in the report after each run.
Step 1: analysis
The program first measures the entire file: overall loudness (LUFS), peak levels (True Peak), and how much difference there is between quiet and loud passages. This takes the natural loudness changes in the track into account – not just single peaks.
The log shows a line with the measured values for loudness, dynamics, and peak level.
Step 2: normalization
Using the measured values, the level is adjusted precisely to your target – as a pure volume shift without extra compression. Quiet and loud passages keep the same relationship; the dynamics of your material are preserved.
What happens next
A new audio file is created. LUFS Converter Pro tries to keep sound quality and file information intact:
- Format and quality: file type, audio quality, and sample rate are kept where possible.
- FLAC metadata: title, album, and other details are preserved.
Where files are saved:
- With a destination folder: originals stay unchanged, new files go to the destination folder.
- Without a destination folder: the original is backed up in the
_originalsubfolder, and the normalized file replaces the file in its original location.
Trial version note
In the free trial, each file is processed for up to 40 seconds – the two-step method is the same as in the full version.
