" We've used the Penteo 3 Pro plug-in as a creative choice to feature music we could only get the stereo elements for.  It creates a fantastic ‘True 5.1’ spatial experience without sacrificing the transient and dynamic ‘punch’, of the original recording. "

Michael Babcock - Sound Designer/Re-recording Mixer at Warner Brothers Studios

" I have found the Penteo 3 Pro to be the best available plug-in to derive 3 channel (L,C,R) and 5.1 channel audio from original stereo music mixes.  It's processing remains faithful to the original music's sound staging, imaging, and timbre. The most recent use was for music in the 'Sound City' documentary "

Gary Summers - Re-Recording Mixer

"Penteo is doing something fundamentally different.  Each channel Penteo produces contains a remarkable amount of discrete information, allowing me tremendous control of the sound field.  I can even push and pull the internal balance of the music to work better with the image and with the other sounds in the mix.  A great experience. "

Pete Horner - Sound Editor/Re-recording Mixer at SkySound

" We've hammered the Penteo 3 Pro plug-in and it sounded awesome, so much so that I used it on the full 'Hunted' series for Cinemax.  Penteo outshines all the other methods I've heard and used to up-mix stereo to 5.1, because ONLY Penteo 3 Pro makes you feel that you are just simply enveloped in the 'music' rather than in DSP of some kind - and for me this really is THE big thing. "

Nigel Heath - Founder and Managing Director at Hackenbacker Audio

" I use Penteo Pro 3 to up mix the stereo source music for the FX Series 'The American's' and found it to be the best stereo to 5.1 and LCR up-mixer. Penteo's 5.1 to stereo compatibility makes it unique: it addresses all the issues of up- and down-mix of stereo music.   Every artist that I have worked with, from Rock to Opera, who has heard Penteo 3 Pro have loved it. It is my go-to up-mix plug-in. "
