Unlimited Creativity Without Complexity
15 creative controls in Penteo 360 deliver faster and more productive Surround 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 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.
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.
Visualizer
Visualize channel strength and see how signals combine around the listener across all axes at the same time. See sound separation visually, and also how channels combine around the listener.
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.
1-Click Social Media Audio
Eliminate the time and complexity to create 360 audio for social media. Presets output high quality 1st or 2nd Order Ambisonics rendered in Binaural with just one-click. Both orders are then preloaded into the A | B utility for fast comparison.
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 four center modes together to rebalance the soundfield.
Rear 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.
Binaural Renderer
Render high-quality Binaural post up/downmix using Penteo’s embedded Binaural renderer. Visually monitor Binaural channels and Surround channels at the same time for any supported audio formats.
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.
