Frequently asked questions
What makes it sound 3-dimensional?
A slow left-right sweep plus a long reverb tail. The sweep moves the image, the reverb hides the transitions.
Do I need headphones?
Strongly recommended. On speakers the sweep is less convincing because both channels play from one point.
Is the file uploaded?
No, the preset renders in your browser.
