Leapwing StageOne 2 — Free Download
StageOne 2 is a stereo imaging plugin that widens stereo audio, adds depth, or creates stereo width from mono sources, using a phase-safe algorithm with three-band control and a visualizer.

Purpose and Core Benefits
StageOne 2 is designed to give you precise control over your stereo field. Its primary functions are widening stereo audio, adding perceived depth, and giving mono signals a stereo image. The unique algorithm avoids phase and mono-compatibility problems, ensuring clean results even when you push the effect.
Unlike traditional widening techniques, StageOne 2 leaves the phantom center untouched, making it reliable for a broader range of sources. This attention to detail helps bring depth and compatibility to disparate audio elements, so you can trust the result in any mix situation.
Key Capabilities
StageOne 2 widens stereo audio by enhancing the perception of off-center content, creating a richer panorama while keeping the center solid. It also adds natural ambience and depth by using directionally optimized reflections that can psycho-acoustically reposition elements within the sound field.
For mono sources, the plugin creates a stereo panorama and integrates them into a stereo field. This balances mono and stereo elements without sacrificing mono compatibility, ensuring your mix translates well across playback systems.
Workflow and Features
StageOne 2 introduces three-band control over the soundstage, with adjustable crossover frequencies for low, mid, and high bands. This allows you to shape width and depth per frequency range, giving you surgical control over the stereo image.
A unique visualizer displays amplitude, frequency, and perceived stereo width of both input and output signals, helping you see exactly what the plugin is doing. The new Phase Recovery algorithm intelligently identifies and re-aligns out-of-phase components, preventing information loss when summing to mono.
Practical Applications
Use StageOne 2 on stereo buses to widen the overall mix, or on individual tracks like guitars or synths to make them sit better in the panorama. It is also effective for adding depth to background vocals or percussion, making them feel more present without cluttering the center.
For mono recordings, such as vintage keyboards or single-mic sources, StageOne 2 can expand them into a full stereo image, helping them blend with stereo elements. The three-band control is particularly useful for taming overly wide low frequencies or adding sparkle to highs.
