Duet is an audio effect designed to enrich vocals and instruments by creating a thicker, more polished sound. It enhances audio material by adding depth and a smooth, glossy character that elevates the overall mix.

The effect functions by independently pitch-shifting the left and right audio channels, allowing real-time control over pitch without altering the original timing. By introducing delay and adjusting the stereo pan, Duet generates the perception of multiple voices, producing a full and textured sound that enhances musical arrangements.

Beyond doubling and harmonizing, Duet offers a silky chorus effect through pitch modulation, adding movement and richness to synthesizers and other instruments. Its capacity to create lush soundscapes makes it a valuable tool for music producers seeking to add depth and character to their tracks.
