As we know, AAudio is a newer lightweight audio API for Android. It was introduced with Android 8 but had serious bugs on the version. Those were all fixed on Android 8.1.

Anyway, as for AAudio, they said they made it to the same conclusion as me, and OpenSL is their default. T…

[image] jiyongman: Does this mean I can use any lower value if the CPU is powerful enough? Audio hardware is pretty nebulous and any given manufacturer may not necessarily be reporting accurate information to the AudioManager, but generally speaking yes a more powerful CPU would correlate to …
