HARMAN International, a subsidiary of Samsung, has announced the release of Personi-Fi, a hardware-agnostic personal audio platform.
Personi-Fi is a device and cloud-based entertainment system designed to provide users with a simple, personalized audio experience wherever they are. This technology will be on display at the HARMAN CES 2019 showcase in Las Vegas.
Personi-Fi uses a dedicated app to capture the user’s personal sound preferences: how they listen, what they like to listen to, and where they like to listen to it. These preferences are stored in the cloud. Next, specialized signal processing creates sound environments, even 3D sound, which can also be personalized to the user’s device and environment. The processing supports both Bluetooth streaming from smart phone or direct-to-device WiFi / LTE streaming for smart speakers and connected cars. Personi-Fi also features over 200 DSP algorithms and technologies such as Virtual Venues, Individual Sound Zones (ISZ), Clari-Fi, Hearing Profile, and DIRAC Panorama.
On mobile devices, Personi-Fi preferences for each user and their associated devices and services are downloaded from the cloud to the smart phone companion app. The app acts as a bridge between the cloud and the device, as well as a processing engine for Personi-Fi algorithms including Clari-Fi, Virtual Venues, 3D audio, environment optimization, and more. The processed content is then streamed to the Bluetooth device. Because there is no processing on the device itself, it can be any brand or type of Bluetooth endpoint (e.g. headphones, speaker, or car audio Bluetooth interface).
On WiFi smart devices, Personi-Fi preferences for each user and their associated devices and services are downloaded directly to the end device. The Companion App acts only as remote control and microphone for room EQ processing. The smart device then performs all Personi-Fi processing such as listener preference EQ, stereo widening, and room EQ.
In the car environment, Personi-Fi preferences for each user and their associated devices and services are downloaded directly to the end device. The Companion App acts only as remote control. The car then performs the Personi-Fi processing on the head unit or amplifier, including listener preference EQ, Clari-Fi, Virtual Venues, stereo widening, and car seat location EQ. In addition to improved acoustic performance over app-only versions, this integration into the vehicle processing components unlocks a multitude of advanced Personi-Fi features that are enabled through access to in-car technology like microphones, navigation systems, and head unit data. It also integrates with all head unit functions, extending the user’s Personi-Fi preferences to audio controls and audio sources including AM/FM, Satellite Radio, CD, USB and streaming sources. Personi-Fi leverages OTA updates, allowing for custom audio features to be developed, updated and deployed to OEM vehicles running the Personi-Fi embedded app.
