Google earphone Fast Pair Certification and Spatial Audio Certification

1. Fast Pair Certification

1.1 Introduction to Fast Pair

Fast Pair uses the "Nearby" platform to enable one-click pairing with Bluetooth devices. Device manufacturers can implement the Fast Pair specification to offer users an easier out-of-the-box experience, while also managing their devices through the Device Console.

Google Fast Pair Service (GFPS), also known as Fast Pair (FP), is a component of the Nearby platform that enables quick and energy-efficient device pairing using Bluetooth Low Energy (BLE). GFPS is designed to accommodate a wide range of devices, from in-ear headphones to speakers, allowing partners to implement FP functionality across their product lines. The specification also includes several extensions that partners can adopt to offer additional features to their customers.

1.2 Fast Pair Certification Process

Step 1: Integrate and verify GFPS on your device.

Step 2: Prepare a self-test report.

Step 3: Submit your device for certification.

Step 4: Obtain official certification from Google and gain the right to enable GFPS.

2. Spatial Audio Certification

2.1 Introduction to Spatial Audio

Spatial audio creates a sound field that surrounds the listener. With spatial audio, users can perceive channels and individual sounds in locations different from where the audio transducers of the playback device are actually positioned. For example, spatial audio enables users to listen to multi-channel soundtracks using headphones. Even though the headphones only have two transducers to play the audio, spatial audio allows users to perceive dialogues in front of them and surround effects behind them.

Head tracking features help users understand the nature of the spatial sound field simulated around their heads. This experience is only effective with low latency, which is measured by the time difference between head movement and the corresponding shift in the perceived location of the virtual speakers.

2.2 Spatial Audio Certification Requirements

Audio HAL and DSP: Must support a dedicated output path for spatial audio.
Headphones: Must include built-in head tracking sensors to enable head-tracking spatial audio.
Implementation: Must comply with established standards for head tracking using the HID protocol from Bluetooth headphones to smartphones.
Audio HAV v7.1: Required to support spatial audio.

2.3 Spatial Audio Certification

Original Equipment Manufacturers (OEMs) can support spatial audio and head tracking without the need for vendor-specific customizations or SDKs. Mobile phones and tablets that support these features are included in GMS certification, with hardware support indicated by the declaration `ro.audio.spatializer_enabled=true`. Certification for headphones will be available starting with Android 15.
