Quality and sound
Even out the loudness of a whole folder
Your tracks come from different places and some sound much louder than others. You want them all at a similar level.

Open Surco's Settings (⌘ , on Mac) and find each option by its name.

They're all evened out with the setting above, except the ones you changed by hand in the editor.
- The peak ceiling defaults to −1 dBTP. It's a safety limit, not a second target.
- If getting there takes a lot of limiting, the card warns you some punch is lost.
- Evening out re-encodes the audio. Before doing it over an MP3, Surco asks you.
- Saving an evened-out track again doesn't raise it again.
- Traktor cue points are kept, except in ALAC.
