LUFS describes perceived loudness, while true peak limits technical peaks. The presets account for these values and a suitable loudness range, so you do not need to calculate them yourself.
The output is a new file
The input is technically checked and returned as a new MP3 file. The original is never overwritten. The output is checked again for format, duration, and loudness after adjustment.
Not sure what your file needs?
Use the free loudness check to see your file’s LUFS, peak, and true peak first.
