There is a very insightful talk about high performance audio on Android by two Google engineers.

I wanted to read about the Patchfield server, but the link goes to some sort of content-free monstrosity instead of a webpage. Seems likely the rest of the project is just as shoddy.

who do not regard JACK's design as something to be closely emulated.

Yes... The big audio latency on Android is widely cited as a reason why audio gadgets like the iRig cannot work for Android (they tried to port the applications and ran into serious problems)

The shorter your device's consistent latency, the easier it is to use as an instrument in a live performance.

Depends ...

What Jack attempts to do is to provide minimal latency, iirc.

I remember a long thread here on LWN where it was clear that some of the posters had no clue about real-time constraints on audio processing and mixing.

That said, I am puzzled as to what the use-case of Jack on Android is. If all you're doing is playback, you only need consistent latency. And if you're doing audio processing, surely you want a far more powerful system that Android is likely to run on.

That said, "because it's there" seems to be a powerful motivating force :-)

Cheers,

hmmm ... what would you call it then?
an audio dispatcher server ?

I wouldn't call it an audio server :)
