Sphere is a free reverb plugin designed to enhance any audio with natural depth and spatial presence. Its foundation is a modified Schroeder reverberator that delivers smooth and rich reverberation effects, suitable for a wide range of sound sources. The plugin operates exclusively in stereo, providing immersive soundscapes that can bring life to mixes without overwhelming them.

The plugin offers straightforward controls, making it accessible for both beginners and experienced producers. Users can easily adjust reflection, damping, and room width to shape the character of the reverb. Additionally, Sphere features a predelay parameter with up to 250 milliseconds, including an optional filtered feedback path, allowing precise control over the initial echo and tail of the reverb effect.

Sphere’s user interface is crafted with vector graphics, which ensures a sharp and clear display at any size without blur or distortion. The interface supports seamless resizing, allowing users to customize the plugin window to fit their workflow. Separate dry and wet level controls provide further flexibility, enabling smooth blending of the original sound with the reverberated signal for perfect balance in any mix.
