Allows you to fade in/out the sound of apps and sound devices with a single touch. This was created as a solution for my friend who was in trouble, and honestly I don't know what it's used for 😅, but I guess it could at least be useful for smooth scene transitions in your livestream.

Features:

• Toggle action: Fade out first, fade in second and resume previous volume.
• Fade out action: Always fade out to volume 0.
• Fade in action: Always fade in up to the volume you set. Be aware of the volume, especially on devices.
• Adjustable duration: From 0.1 to 10 seconds.
• When fading in, the target volume after the effect is displayed on the key to avoid an unexpected increase in volume.
