Android 15, the upcoming version of Google’s mobile operating system, is set to improve the audio experience on Android devices. According to Sammobile, Android 15 Beta will come with many improvements to wireless audio functions, including Bluetooth Low Energy Audio (LE Audio). This system will bring support for dynamic spatial audio over Bluetooth LE Audio. This highly anticipated feature will provide users with a more immersive and engaging listening experience, particularly when watching content with surround sound.
Bluetooth LE Audio: The Next Generation of Wireless Audio
Bluetooth LE Audio, short for Low Energy Audio, is a new generation of Bluetooth low-power audio technology launched by the Bluetooth Special Interest Group (SIG) at the 2020 International Consumer Electronics Show. It inherits the advantages of Bluetooth Low Energy technology and optimizes audio codec, audio data transmission, and audio control.
Bluetooth LE Audio offers several benefits over traditional Bluetooth audio, including lower power consumption, improved audio quality, and support for multiple simultaneous connections. This makes it an ideal choice for mobile devices, where battery life and audio performance are crucial factors.
Dynamic Spatial Audio: Bringing Immersion to the Next Level
Dynamic spatial audio is a technology that creates a multi-directional audio experience, making it feel as though the sound is coming from various directions around the listener. Unlike traditional audio, which is confined to the left and right channels, dynamic spatial audio allows sounds to appear to originate from above, below, or even behind the listener, adding depth and realism to the audio experience.
Android 13 already supported Bluetooth LE Audio and spatial audio, but it did not support the combination of Bluetooth LE Audio and dynamic spatial audio. Android 15 changes this, bringing a more immersive audio experience to users. Thus, with the Android 15, the company is bringing more upgrades to this feature.
Improved Head Tracking and Bandwidth Utilization
One of the key advantages of implementing dynamic spatial audio on Bluetooth LE Audio is the reduction in head tracking latency and improved bandwidth utilization. Karthic Veera, Android Media and Camera Product Manager, stated that this combination “provides lower head tracking latency and better bandwidth utilization, resulting in a more immersive experience.”
By reducing head tracking latency, the audio will feel more responsive and in sync with the user’s movements, creating a more seamless and natural experience. Also, the higher bandwidth utilization ensures that it can transmit more audio data. During the transmission of data, it will not compromise quality or performance.
Compatibility and Availability
The dynamic spatial audio feature based on Bluetooth LE Audio is expected to appear on eligible Samsung Galaxy smartphones and tablets with the One UI 7.0 update later this year. This means that owners of compatible devices will be able to enjoy a better audio experience once the update is official.

It’s important to note that for dynamic spatial audio to work, the connected headset or earbuds must have head-tracking sensors and support Bluetooth LE Audio. As more manufacturers adopt this technology, the availability of compatible devices will increase, making the feature accessible to a wider range of users.
Auracast: Sharing Audio with Multiple Devices
In addition to dynamic spatial audio, Android 15 will also enable the Bluetooth “Auracast” function. Auracast is a broadcast audio feature that allows users to share audio content with multiple Bluetooth-connected devices simultaneously.
In the Android 15 Developer Preview 2 update, Google introduced an “audio sharing” page, which will serve as the dedicated hub for Auracast functionality. While the feature was not fully functional in the initial release, the recent Android 15 Beta 1.1 update has enabled it on Pixel 8 Pro phones.
On the “Audio Sharing” page, users will be able to control and manage their Auracast settings. They can choose a broadcast name and password under the “stream settings” heading, allowing them to customize their audio-sharing experience.
Also, users can tap on a QR icon to generate a QR code that others can scan to connect to their devices and receive the shared audio. This streamlined approach to connecting multiple devices will make the Auracast feature more accessible and user-friendly.
This feature can be particularly useful in scenarios where multiple people want to listen to the same audio content, such as in a classroom or during a presentation. By enabling Auracast, Android 15 will make it easier to share audio and create a more collaborative listening experience.
Conclusion
Android 15’s support for dynamic spatial audio based on Bluetooth LE Audio is a significant step forward in mobile audio technology. By providing a more immersive and engaging listening experience, particularly when watching content with surround sound, this feature will enhance the way users consume media on their Android devices.
The combination of lower head tracking latency, improved bandwidth utilization, and the ability to share audio with multiple devices through Auracast makes Android 15 a compelling update for audio enthusiasts and casual users alike. As more manufacturers adopt Bluetooth LE Audio and head-tracking technology, the availability of compatible devices will increase, making this feature accessible to a wider audience.
In conclusion, Android 15’s support for dynamic spatial audio based on Bluetooth LE Audio is a game-changer in the world of mobile audio. It promises to deliver a more immersive and engaging listening experience, setting a new standard for audio quality and functionality on Android devices.
