Does Soundtrap automatically mix?
Soundtrap automatically masters your project when you click "Save", so that it is instantly enhanced and ready for reaching the Billboard Hot 100. :) However, at the moment we do not support any way to customize the mastering settings.
How do I make my Soundtrap sound professional?
Just hover over the region you wish to auto-tune, click EDIT (1) and choose Auto-TuneĀ® (2). This opens up the Auto-TuneĀ® effect dialog! Here you can choose the amount of the effect that you want to add and select a musical scale. The Amount control goes from Light to Heavy.
