One interesting innovation of mobile iOS 16 has been personalized spatial sound technology: the user can create a personal sound profile based on the individual features of his hearing organs, and the spatial sound of the AirPods headphones will be optimal.
The creation of an individual profile involves a whole procedure involving scanning the ear shells with the frontal camera TrueDept: it takes about a minute to keep the iPhone at a distance of 10–20 cm. However, before Apple, Sony offered the same idea. In 2019, the Japanese manufacturer released 360 Reality Audio technology together with its supporting music services Amazon Music, Tidal, Deezer and Nugs.net. The idea is indeed very similar: scanning the structure of the earshell and setting up a spatial sound treatment based on the user's physiological characteristics.
The creation of an individual profile for Sony 360 Reality Audio involves a more labour-intensive process than Apple ' s solution. In addition, in the latter case, personalized spatial sound is created by iOS forces, and Sony proposes the installation of the Headphones Connect application and the use of the cell phone. Apple uses a more suitable TrueDept sensor for this purpose, but throughout the beta test period, iOS 16 users complained that the process is sometimes prolonged and the ear is not always detected.
The individual sound profile created by the iPhone owner will subsequently be available on many Apple ecosystem devices after the release of the updated MacOS and iPadOS. The technology is compatible with Third Generation AirPods, AirPods Pro, and AirPods Max.
