Unlimited Creativity Without Complexity
22 creative 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 even-out sounds and create the impression of increased ambience at the expense of signal definition and channel separation. Any downmix compatibility impact is indicated on Penteo’s ITU Downmix Monitor.
4 Faders
Take precise independent or multi-link control over the Center, Side and Rear channel energy. Any energy added or deleted is re-balanced across the entire surround bed ensuring 100% ITU downmix compatibility.
Legacy Upmix DSP
Penteo 360’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
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
Low Latency Mode
Every Penteo upmix is processed uniquely depending on the original mix. so a short preview is needed to separate the discrete audio components. Low Latency mode shortens the preview lowering 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 four center modes together to rebalance the soundfield.
Decorrelated Upmix DSP
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
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, and Diverge to avoid center channel overload. All settings downmix 100% ITU to source.
