Qualcomm has decided to implement support for the aptX and aptX HD (High Definition) audio codecs in the AOSP (Android Open Source Project) repository, which will enable the use of these codecs across all Android devices. This only pertains to the aptX and aptX HD codecs, while more advanced versions such as aptX Adaptive and aptX Low Latency will still be available separately.
The aptX and aptX HD codecs (Audio Processing Technology) are used in the Bluetooth A2DP profile and are supported by many Bluetooth headphones. However, due to the necessity of paying royalties for integrating the aptX codecs, some manufacturers, such as Samsung, have opted out of supporting aptX in their products, favoring codecs like SBC and AAC instead.
