How Does Pioneer’s SPHERA Radio Work?

By James Chevrette

The announcement at CES of Pioneer’s new SPHERA radio, the first in the aftermarket with Dolby Atmos, invited a lot of questions, so we reached out to Robert Mony of Pioneer USA for a deeper dive into the radio’s workings.

We reported that Pioneer’s new SPHERA radio allows users of CarPlay to playback Dolby Atmos, a form of spatial audio. To do that, Pioneer’s SPHERA needs the following:

• Dolby Atmos content via Apple Music, Amazon Music Unlimited or Tidal
• Playback via Apple CarPlay (wired or wireless version)
• Pioneer SPHERA unit

If the content is not Dolby Atmos music but still coming from Apple Music via Apple CarPlay, then the user has the opportunity to turn on a setting that will upscale the original audio source in a way to create a better sound. This will not be the real Dolby Atmos/Spatial Audio experience, but it will still be better than the basic stereo source playback.

If Pioneer SPHERA is not connected through Apple CarPlay and not using Apple Music as the Atmos source, then the unit will switch into a regular audio processing mode and play the audio the same way as a typical head unit. Any other source, Android, USB thumb drive, SXM or basic, aux. in or tuner will be played in regular stereo mode.

Will we see Spatial Audio on Android Auto soon?

“It will come for sure; it’s just a matter of time,” said Mony. On the OEM side, Android is already working with QNX in their joint structure called AAOS. “QNX is the backbone structure with Android Automotive acting as the user interface, etc. Android also has some kind of pressure from the smartphone and streaming industries. To name a few, Apple Music, Amazon Music and Tidal are already offering Dolby Atmos content. The only big streaming platform currently not offering it is Spotify. They are late adopters, think about how long they took to bring Hi-Res audio into their services.”

How does SPHERA work to bring Spatial Audio in the car?

It starts with Pioneer’s Pure Auto-Tuning technology which is the evolution of the original Pioneer Auto-EQ/Auto-Time alignment. It is now redesigned to work with Spatial Audio and Dolby Atmos. It’s part of the first unit boot sequence, under a basic step-by-step guide on the unit’s screen and it’s also available within the settings if you need to refresh your tuning preferences based on possible changes in the car. For example, if you upgraded your speakers, you will have to calibrate the system to make the most of the Pioneer’s SPHERA technology.

This calibration is done from the center of the driver’s seat headrest. Basically, the Auto-Tuning technology will look at how the different sounds and frequencies will either bounce or be absorbed in the cabin of the car. It acoustically analyzes how the trims, shapes, and textures of the different materials of the car will interact with each single audio source point. The SPHERA will then save this “recipe” and apply it in real-time to adjust the Atmos/Spatial audio content to work with as few as four speakers.

What Is Dolby Atmos?

Dolby Atmos is a form of spatial audio that uses up to 128 audio objects. An object can be the singer, and another the bass guitar or drums. Each is recorded as their own separate audio track that is assigned to 3D positioning based on the playback time. Using the Auto-Tuning results, the Pioneer SPHERA will move, in real-time and independently, the audio objects and apply the audio corrections required. All this is based on Pioneer’s acoustic mapping of the vehicle and for each audio object.

“This means what we do for the singer will not necessarily be the same for the guitar or the drum, or any other audio object. Keep in-mind that they are independent of each other. So, as you may understand, here, this is totally different than what we know from a stereo source and where all your instruments and other audio sources are locked all together within a left and right channel. With a stereo source, it’s impossible to ‘work’ on the singer’s vocals without affecting the guitar. With Atmos, it’s a totally different scenario,” Mony said.

SPHERA’s new technology will be available for demonstration at The NAMM Show, Jan. 22-24th, 2026 at the Anaheim Convention Center Booth #14312.
