5 Oscar Winning Sound Designer Steve Pederson Steve Pederson “What’s important is how Penteo keeps the integrity of the 2-track file, isolates the center channel just right, generates the interesting and isolated surround channels, and keep the bass tight. Penteo is the up-mix plugin for me when I’m mixing.” Free Class

4 Ken Hahn, Co-Owner & Supervising Sound Editor Ken Hahn ”Because of the historical nature of the “Live from the Met” recordings, it is imperative that we not alter the sound when up-mixing to 5.1 surround, and that’s why we use Penteo.” Free Class

    • "Penteo generates the 5.1 surround without adding any additional delays, equalization, frequency shifting, dynamic change, alteration, or any of those tricks. It uses a new method to up-mix that doesn’t alter the original stereo."
    • "Penteo 4 isn’t the first plugin to convert stereo to surround, but it sounds like the best.... Unlike similar plugins, the sound was full, had clearly defined channels, and seemed to compliment the original mixer’s intentions."
    • "I have tried Penteo on a great deal of content from easy to potentially troublesome and it copes very well. Penteo is as good as it gets for broadcast, you will not have to be worrying about your fold-downs. Penteo is great sounding and a highly effective and efficient plug-in."
