Well as always there are pros and cons(just seen so far while fiddling around with it for an hour or so):
- seem to be more resource friendly but not reliable. If you rapidly trigger audio files, sometimes there is no signal being played. What I’ve seen so far volume changes don’t have an effect on iOS; Android seems to be fine
- and not to forget the bug, that they can not play resource files QTBUG-36175
- low latency
- resource hungry
- and if the Qt docs prove to be right also not reliable when it comes to multi-timbrality (several SoundEffects played simultaneously)
- and from my own findings: if you create an entity that contains a SoundEffect on iOS, the performance drops drastically, and you can end up with a dropped framerate / sluggish UI update
I think those type are to diverse to come up with a generally valid conclusion.
