FAQ
Questions about the add reverb.
What do decay and pre-delay mean?
Decay is how long the reverb takes to fade (RT60). Pre-delay is the gap before the reverb starts; 20–60 ms keeps vocals clear while still sounding big.
Why does the export end later than the song?
We let the reverb tail ring out naturally after the last note. You can turn that off in the export dialog.
Can I add reverb without slowing the song?
Yes — the Dreamy Reverb preset keeps the original speed.
