Near-identical sound in every seat

Highest Quality
Soundstage 

Award-winning
phaseless upmix DSP

Optimized for ADI's SHARC platfrom

Legacy upmixers have failed in automotive because they drastically alter the upmixed sound which sounds bad in cars.  And tuning to the driver via delays and levels fails to delivery a quality sound stage to every seat.

PerfectSurround's unique phaseless upmixer does not alter the sound:  nothing is added, deleted or sonically modified in Penteo's upmix DSP. 

Automotive listeners are bathed in the highest quality immersive  soundstage possible, with our post-upmix advanced automotive tools delivering near-identical sound performance to every seat.

Multi-seat

sound

 

PerfectSurround Automotive adds phase-equalization instead of delays post-upmix to eliminate any near-side biases in the car. 

We correct for all acoustic issues outside of the upmixer releated to distance, delays and the creation of a phantom center for each seat.

 

This results in a near-identical sound experience for every seat location across all frequencies.

PerfectSurround DSP Powers the Penteo Upmix Audio Plugin

In film, TV and gaming, sound creators and designers use upmix audio plugins to convert stereo to Surround, Atmos, Auro3D, DTSX and Ambisonics formats.   Because of broadcast, all formats must also downmix cleanly back to the original stereo.

Nothing is added, deleted or sonically modified in PerfectSurround's phaseless DSP making it the only DSP that does not colorize the sound. Therefore, very Penteo upmix downmixes perfectly back to the original source, 100% ITU. 

Most major film, broadcast/streaming and gaming studios rely on Penteo for upmixing/downmixing sound.

Penteo is used by content creators, sound designers and composers in 50+ countries.

PerfectSurround Lossless DSP

Nothing is sonically added, modified or removed from the original source in PerfectSurround’s award-winning phaseless upmixer.   Our unique DSP divides content into common, intermediate and differntial signals so they can be steered between front, side and rear speakers.  Because of the sonic clarity with zero tonal coloration in our DSP, every upmix is treated uniquely yet remains faithful to the original source.  PerfectSurround is easily optimized to any car or seating configuration.    

3CentreModes.png

Three Center Extraction Modes

 

Our Center extraction modes provide maximum control over how sound energy is put into the center channel.  Default mode blends phantom/discrete into one channel which is ideal for all music types.  Discrete creates the most focused center image,.  Composite enhances the center image if delays are being used.

Precise Bass Management

 

By automatically phase-aligning the center, sub and front low frequency speakers, additional low frequency punch is heard in every car seat.  Four LFE controls manage how low frequency effects are distributed across channels.

All Formats Supported

 

We upmix to every Dolby Surround format including 3.1 LCR, 4.1 Quad, and 5.1 / 7.1 Surround.  All formats can be implemented without a LFE/sub-woofer channel.  Quad mode supports cars with no center channel and LCR mode is for cars without rear speakers.
