Deepen every immersive dimension of your upmix with Decorrelation Suite
Take independent control over: Individual channels | Surround Bed | Bass | LFE
Decorrelation is more than ‘just diffusion’. Penteo Pro+ makes it easier than ever before to take total creative control over every dimension of your upmix — while preserving a bit-exact downmix.
Fast results. One-click modes & smart defaults improve spatial placement & separation resulting in more realistic upmixed ambiances that sound distinct without being artificial.
Best of both worlds. Smart defaults ensure perfect downmix compatibility. Or disable smart defaults to unlock full artistic freedom with every creative control at your fingertips.
Supercharge your upmix into a captivating immersive experience through a naturally diffuse and multi-layered soundfield with unmatched depth, width, and realism.
Beta testers love Penteo’s Decorrelation Suite
“Having a dedicated Wide fader alone is worth the update”. Also that I can bypass the wides is powerful.”
”The synth LFE bands are quite spectacular to control, with a phenomenal sounding result”
“The new Surround bed ‘depth’ mode is absolutely amazing, great addition, is my new default”
“From the heat on the mix stage, thank you for the more responsive DSP in version 8, it made the difference on a very musical track”
“Awesome new Surround divergence control. I love being able to control the relative balance between keeping focused sounds in front and more surround diffuse results.”
“The 3 LFE frequency bands sound great. Other plugins have a bad distinctive synthesized ‘tone’ to their sub frequencies, where it feels that it has more bass. Your DSP has none of that - EXCELLENT WORK”

We use Penteo’s stem bypass to decorrelate"vanilla" stems and bring them further into the room. We love it on drums, employing Penteo as a "crush" effect by heavily compressing the duplicated signal before using Penteo to generate more excitement from the drums.

Penteo is the best way to upmix stereo sources and create the illusion of space in Dolby Atmos while staying 100% true to the source material. I now use Penteo in all my music mixes.

Decorrelate Individual Channels
Stem Bypass
Removes the Atmos channel pair, redistributing energy within your upmix to create enhanced spatial separation and punch.
Ideal for carving space between vocals & music or keeping effects out of the rears.
Preserve or Override ITU
Every Stem Bypass downmixes 100% ITU to source, but often creative mixing goals supersede the need for downmix compatibility.
When deactivated, all controls are enabled for full downmix creativity with any incompatibility ndicated on Penteo’s ITU Downmix Monitor.
Stem Passthrough
Removes the Surround channel pair redistributing energy within your upmix, then the original input pair is automatically blended into the upmix.
Passthrough keeps iconic Surround-field channel pairs - such as a well-known L/R song - in the upmixed mix with zero extra bussing needed.
I needed to upmix Stereo to 7.0.4 Atmos for a contemporary classical composition. I only had a wet track with a baked-in long reverb. I used Stem Bypass in the Decorrelation Suite - it was so effective!

Penteo Pro+ with the Decorrelation Suite takes upmixing to a new level while still providing 100% ITU downmix peace-of-mind. Penteo is in my Dolby Atmos template - it’s my go-to when I want to spread a stereo source around the room.

Surround Bed Decorrelation
Divergence Dial
Take control how Penteo slices and separates diffuse sound energy between front & surround channels.
Dial the balance between a tightly focused front-stage to more spatial diffusion with a greater sense of surrounding depth.
Immersion DSP
Depth setting tightens control over direct and diffuse energy resulting in less dry energy distribution and more ambients to the Surround channels.
Depth is the new session default, ‘Vintage’ setting can be selected for an alternative immersion effect.
Total Channel Control
Fast upmix changes from dedicated fader, diffuse, shelf, boost/tilt, vocal isolation & sound shaping modes are on each channel.
Unless disabled, smart downmix compliance defaults guarantee that no energy is lost in the upmix.
Penteo's new synth LFE sounds awesome and so does the Depth immersion algorithm which delivers much more stereo separation in the upmixed channels. The divergence dial opens up new creative placement possibilities. I love how easy it is to turn out lush multichannel atmospheres that also sound great in the downmix.

Decorrelate LFE - Get more thump, rumble and upmix punch
Expanded Main LFE Controls
Add up to 12 dB and boost LFE content without removing LF energy from the main channels or split LFE. Set crossover frequencies, or use Diverge to avoid overloading the center channel.
ITU-R 1384 and Music
Matches the ITU spec to prevent clipping, this setting attenuates the input main channel LFE by -10dB. For creative LFE control for music stems, use Music setting which does not attenuate the LFE thereby allows complete creative control.
Penteo works really well in all my musical workflows. I use it to broaden tracks into the immersive soundscape using decorrelation which results in an excellent ‘live arena’ feel to my audio stems.

Sub-Harmonic Synthesis
Add more low frequency rumble, thump and punch with Penteo’s synthesized sub-harmonic LFE controls. Take precise control over three frequency bands that can be individually muted or linked to other bands for faster workflows.
I use Penteo 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.

The most musical Bass decorrelation
Precise Bass
Precise bass mode is not compensated which provides tighter, 100% ITU bit-exact downmix compliance.
Perfect for pop, rock, and modern productions that demand punchy, controlled low end.
Acoustic Bass
Acoustic bass mode is compensated to deliver a warm, full-bodied bass with acoustically perfect phase alignment and 100% ITU downmix compatibility.
Ideal for orchestral, film, and reverberant material.
Intermediary Formats
Penteo uniquely shapes Bass for Sony 360 Reality Audio & Octophonic formats, so using them as an Intermediary before upmixing to Atmos delivers one-of-a-kind results.
Use in conjunction with Stem Bypass to for advanced decorrelation results.
