Patchfield introduces concepts of JACK audio server to Android (Libre Graphics World)Libre Graphics World takes a look at the just-announced Patchfield audio server for Android. "In a nutshell, Patchfield reuses the cornerstone idea of JACK — creating standalone applications for audio generation and/or processing and connecting them in a patchbay." The fact that Patchfield brings advanced audio-processing capabilities to Android sounds like a plus in many ways, but there are evidently detractors who do not regard JACK's design as something to be closely emulated.

I wouldn't call it an audio server :)

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

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,

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)

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.

Which page are you referring to? :)
