We are in 2012 dear google, linux can go much lower than that,
the devices out there are blazzingly fast, 40ms is insane.
Android 4.1 brings ~10ms latency *on the right hardware*
But well, that's life. This is "consumer electronics" after
all. If angry bird works...
There are use cases for low latency audio on consumer devices, and I
think there is a push for a better performing audio stack.
Note though, that in this example program, while the audio output is
rendered in C, the final pass to the AudioDevice goes through java (the
java code calls the JNI code to render into a buffer). But since under
the android OS, there's just a linux system, it should be possible
(maybe with root access and some hackery) to access the ALSA layer
directly. And then it only depends on the audio hardware in the device.
