A direct competitor that uses patented . Ranked #1 in double-blind listening tests, DTS Neural analyzes the full frequency spectrum to place specific audio elements (like a guitar or a train whistle) into discrete channels, creating a highly aggressive and "loud" surround image often favored for action movies.
Set the "Rear Reverb Type" to "Hall" or "Ambient." Turn the dry/wet mix to about 30% for the rears only. For the Surround delay, start at 15ms. This creates the Haas effect —your brain will perceive a wider soundstage without hearing a distinct echo.
Unlike basic "stereo spreaders" that simply duplicate sound to the rear speakers with a delay, the V.I suite uses psychoacoustic algorithms. Its name—"V.I"—implies "Virtual Intelligence" or "Variable Imaging," meaning the software intelligently identifies which elements of a stereo mix belong in which spatial domain. v.i stereo to 5.1 converter suite
The suite provides professional-grade matrix decoding capabilities entirely free of charge.
At its core, the V.I Stereo to 5.1 Converter Suite is a sophisticated software application (often available as a VST plugin, standalone application, or DirectX module) designed to analyze a standard Left/Right stereo signal and redistribute it across six discrete channels: Left, Center, Right, Left Surround, Right Surround, and the Low-Frequency Effects (LFE) channel (the ".1").

Import your stereo file (e.g., a 44.1kHz/16bit WAV of a classic rock song). Ensure the input gain is set to -6dB to provide headroom for the surround processing.
In the modern landscape of audio production, the ability to deliver immersive, high-quality audio is paramount. While (5.1) has become standard for movies and premium music, vast libraries of content remain in stereo . Bridging this gap—converting traditional 2-channel stereo audio into a fully immersive 5.1-channel experience—requires precise, specialized tools. For the Surround delay, start at 15ms
Are you looking to use this suite as a or as a plugin inside a DAW?
The suite includes specific controls for the Low-Frequency Effects channel. It allows the user to synthesize bass from the stereo mix and direct it to the subwoofer. This is crucial for film mixing and club environments where low-end physical impact is required.
Originally popular as a specialized VST plugin suite, the V.I architecture focuses on transparency and phase accuracy. This ensures that the newly created surround soundstage feels natural, avoiding the hollow or metallic artifacts common in low-quality upmixers. Key Features and Capabilities
Many users ask: "Why don't I just let my Denon or Yamaha receiver do the upmixing with Dolby Pro Logic II or DTS:Neo?"
