Immersive sound experiences with Dynamic Spatial Audio

This solution is optimized between phone and earbud to ensure extremely low latency for a more natural and immersive spatial audio experience. On the phone, the spatialization and stereo rotation is supported by the Snapdragon® 8 Gen 2 Mobile Platform, and on the earbud side the QCC3081 delivers earbud to earbud cross head rotation alignment, low power consumption for the earbuds for longer periods of wear, optimised latency for a lag free experience and our own proprietary head orientation algorithm. ​

Integrated, hybrid adaptive noise cancellation

QCC3081 supports our third-generation Qualcomm® Hybrid Adaptive Active Noise Cancellation (ANC), which utilizes an integrated, dedicated hardware block on the platform. Our 3rd generation Hybrid Adaptive ANC enhances the listener experience by adapting to fit and to external environments, whilst helping developers solve commonly faced issues such as wind noise, howling and adverse events. By bringing these solutions to our Adaptive Transparency Mode, paired with automatic speech detection, users will experience smooth transitions from immersive noise cancelling to natural sounding pass-through when they need to hear the world around them. Plus, we achieve all of this at low-power consumption, due to its tight integration within the platform hardware. Plus, we achieve all of this at low-power consumption, due to its tight integration within the platform hardware.  ​
