Mono/Stereo is a compact utility plugin designed for Pro Tools that efficiently converts audio streams between stereo and mono formats. It operates by transforming Left/Right stereo signals into Mono/Stereo (Sum/Difference) signals and can reverse this process, providing flexible control over audio channel formats. This makes it an essential tool for managing and manipulating sound fields within mixing and mastering workflows.

The plugin is structured to work seamlessly with effect chains containing multi-mono plugins or processors that handle channels independently, ensuring accurate and precise audio transformations. Within its interface, the left channel represents the Mono (Sum) signal, while the right channel corresponds to the Stereo (Difference) signal. This clear channel distinction facilitates intuitive routing and processing in complex audio projects.

Mono/Stereo supports both AAX Native and AAX DSP formats, offering compatibility with a wide range of Pro Tools systems and hardware configurations. Its focus on efficient channel conversion makes it a valuable addition for sound engineers looking to optimize stereo imaging and mono compatibility in their sessions.
