Creative control








I used Penteo for upmixing Atmos 7.1.4 for Pearl Jam & A-Ha in HBO's Emmy award-winning "The Last of Us". Penteo is always phase coherent that results in a lot less equalization work later.
I’ve used Penteo for a decade & have found no equal for balanced & tasteful separation of vocals & instruments, without steering artifacts.

I use Penteo's upmixer/downmixer extensively because it delivers the best and most cohesive upmix to Dolby Atmos 9.1.6. I can add LFE content without overbalancing the low end using the LFE Split control.

Penteo upmixed Stereo / 5.1 Surround to 7.1.2 Atmos on the film Bulletproof 2. I love Penteo's reliable overhead modes that keeps 100% downmix compatibility which is no easy feat!

Exceptional sound
Unlike typical upmixers that rely on phase manipulation, reverb, or delays to create immersive effects, Penteo’s award-winning phaseless upmix DSP precisely follows the original sound placement with zero unwanted artifacts.
Nothing is added, removed or altered in a Penteo upmix which ensures clarity resulting in a natural, transparent sound: every upmix sounds exactly as intended, for any audio format.
Never again need to choose between an optimal upmix versus a near ‘exact’ downmix.
