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!

We needed to upmix multiple Stereo masters into Dolby Atmos for Netflix's Yeh Ballet at Abbey Road Studios. Penteo's Atmos 7.1.2 upmix sounded incredible - its a joy to use.

Exceptional Sound
Unique Phaseless Upmix
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.
Penteo creates wide channel separation, maintaining the depth and clarity of the original audio.
And Penteo’s advanced controls unleash the most upmix creativity with more precision resulting in a more authentic immersive experience from every upmix or downmix for any audio format.
Penteo’s phaseless upmix DSP introduces no unwanted artifacts, phase issues or alterations, therefore Penteo upmixes always downmix back to any original source format with perfect 100% ITU compatibility.
Every Penteo upmix is a 100% ITU downmix - never again need to chose between an optimal upmix versus a near ‘exact’ downmix.
Downmix compliancy is not limited to Stereo-only, Penteo delivers the optimal upmix with a 100% ITU downmix up to 62 audio formats, every time, ensuring no loss of fidelity or spatial accuracy.
This is critical for every audio application including broadcast, remastering, sound, and repurposing content across film/TV/streaming/VR/AR/Headphone platforms.
Every Upmix = 100% ITU Downmix
Penteo is an important plugin for my Surround & Atmos upmixes. For any audio format I need, Penteo reversions into a single well handled spatial workflow. Penteo always sounds amazing.

After using Penteo for many years, it has become such an essential upmixer to me that no self-respecting Atmos or Surround sound designer should be without it.

I'm loving Penteo's flawless 5.1 Surround to Dolby Atmos 7.1.2 upmix. Penteo sounds great on all music stems and sound effects, and it's easy to upmix any format from a single upmixer/downmixer..

Unlimited Atmos Upmix Creative Control
22 controls in Penteo Pro deliver faster and more productive Atmos workflows
Minimal Size
Minimal reduces plugin size by 60% to free up screen-space for big sessions yet still offers full access to monitor and control all of Penteo’s key operations. When Minimal is enabled, the Penteo Visualizer and Mute/Solo are disabled.
Rear and Upper Diffuse
Add a diffuse effect post-upmix to create the impression of increased ambience at the expense of signal definition and channel separation. Any downmix impact is indicated on Penteo’s ITU Downmix Monitor.
4 Faders
Take precise independent or multi-link control over the Center, Side, Rear and Overhead channel energy. Any energy added or deleted is re-balanced across the entire surround bed ensuring 100% ITU downmix compatibility.
Legacy Upmix DSP
Penteo Pro'’s phaseless DSP is optimized for Stereo to Surround upmixing. Legacy DSP also matches the DSP found in Penteo 7 Pro Suite ensuring continuity for legacy Penteo sessions.
Left / Right Sweep
Creatively shape the L / R upmix components. Sweep the audio in around the listener when automated with front/surround balance controls. Any downmix impact is indicated on Penteo’s ITU Downmix Monitor.
3 Upper Sound Modes
Shape overhead channel energy with four sound modes: Low for ambience & transients, Raise to create spaciousness, Max for overhead emphasis and Master Mute saving time versus muting channels individually.
Visualizer
Visualize channel strength and see how signals combine around the listener in 3D across all axes at the same time. Or, see sound separation visually with even more detail using a dual 2D / 3D view.
3 Center Modes
Take complete control over center energy with three sound modes – Default Music, Discrete and Composite. Each mode processes the center channel differently for creative widening or narrowing effects.
Drop VOX
Enabling Drop Vox isolates the majority of dialog from the overhead channels by eliminating the center channel sound energy component from the overhead channels.
Low Latency Mode
Every Penteo upmix is processed uniquely depending on the original mix. A short preview identifies discrete audio components before the upmix DSP. Low Latency mode shortens the preview lowering overall latency.
Center Mono-like Sounds
Automatically isolates and centers mono-like stereo inputs overriding the normal upmix process. Use Autodetect Mono with center fader and center modes together to rebalance the soundfield.
Decorrelated Upmix DSP
Decorrelated DSP is optimized for 2 or 3 level immersive sound formats above 7.1 Surround but can be used on any format. Whenever an immersive format beyond 7.1 is selected, Decorrelated DSP is automatically selectect.
Rear and Upper Shelf
Rolls off high frequencies from the rear channels post-upmix thereby centering the upmix while preserving a warm, natural sound. Ideal for subtly creating airiness in vocals, enhancing tonal balance and mix clarity, any downmix impact is indicated on Penteo’s ITU Downmix Monitor.
Boost
Boost creates the acoustic effect of pinning the rear channels forward with the front sound stage. Side surround energy is increased by reducing the rear channels with no loss of downmix integrity.
Overhead Tilt
Tilt mode shifts upper channel energy from rear to forward channels which is useful when needing to spatially focus overhead channels for greater sonic impact.
ITU Downmix Monitor
When post-upmix controls are enabled, any ITU downmix compatibly is displayed in percentage and in red. Pressing ‘Perfect’ removes all settings, restoring 100% ITU downmix.
LFE Controls
Take complete control over LFE with frequency crossover settings, Boost/Split for how LF energy is removed from the main channels, & Diverge to avoid center channel overload. All settings downmix 100% ITU.
After an upmixer shootout we selected Penteo to upmix 5.1 reverbs to Dolby Atmos 9.1.6. The usability and clearness of Penteo's sound is astonishing & the perfect phase accuracy for the downmix back to stereo is a lifesaver.

It’s hard to mix Stereo into and immersive space but Penteo’s Ambisonics upmixer nails it. Penteo’s visualizer is unique and having the ability to switch between Ambisonics orders and formats on-the-fly has really streamlined my workflows.
