Strictly speaking, the specification for 5.2 LE Audio is not yet released. For evaluation you might be interested in seeing the LE Audio evaluation kit that was announced at the start of the year - which has yet to be released. For questions about this product please contact your RSM ( Regional Sales Manager ), if you do not know who this is please sent me a PM with you information and I will give you their contact information.
which is suggested best?
All of our SoC's that are BLE 5.2 LE Audio compliant will perform equally in regards to fulfilling the LE Audio specifications. Which SoC that is best therefore primarily depends on what other things that will go into your application. For example, if you require a larger FLASH or RAM memory, or certain peripherals only available at certain SoCs, etc. It is therefore hard to recommend one SoC over another, based on the given criteria.
