Audiophiles ripping rare quadraphonic vinyl from the 1970s often find the rear channels are degraded. VI Suite can "repair" the phase coherence of a vinyl rip, extracting the rear channels from the stereo grooves with 90% less surface noise.
It respects the original stereo image while guessing (brilliantly) what the sound would have been if the artist had an array of six speakers in 1969. For audio engineers looking to monetize old catalogs or elevate indie films, this suite is not just a tool; it is a time machine.
Many classic games (early 2000s) have incredible soundtracks but are locked to stereo. Running the audio through the VI Converter Suite revitalizes these games, allowing you to hear environmental sounds behind you.
Before diving into the software, it’s important to understand the challenge. Standard stereo audio is mixed for two channels (Left and Right). A 5.1 system requires six distinct channels: vi stereo to 51 converter suite exclusive
Standard stereo tracks mix bass into the left and right channels. The Vi Converter Suite features a precision low-frequency effects (LFE) crossover slider. This allows you to choose the exact frequency cut-off (e.g., 80Hz) to route deep bass away from smaller satellite speakers directly to your subwoofer. Step-by-Step: How to Convert Stereo to 5.1
Whether you are in Pro Tools, Logic Pro, Nuendo, or Ableton Live, the integrates as a standard multichannel plugin (AU/AAX/VST3).
Many upmixers create phase cancellations, making audio sound "out of time" or thin. This suite ensures perfect phase coherence. Audiophiles ripping rare quadraphonic vinyl from the 1970s

V.I was not a standalone program. To actually use the plugin, you need a "VST host"—a piece of software that can load VST plugins. Over the years, users have successfully tested the V.I Suite in a wide range of hosts, including: For audio engineers looking to monetize old catalogs
