So they still haven't addressed the horrendous audio latency issue. Unbelievable.

It's a shame because Android is such a nice OS.

I believe it. That's why I switched to an iPad.

Yes it is.

They are in the process of addressing it in Jelly Bean. There was a slide about it during the "What's New in Android?" talk at Google IO. I guess you'll have to wait for that session video before you can see it yourself.

A question about it was asked in the Q&A at the end. Basically Chet was unwilling to give any hard millisecond data because the "significant improvements" they made are "very device specific". They are also continuing to work on it further.

They also added USB audio output support to Jelly Bean see:

So it looks like we lucked out, the very last question of the Android Fireside chat was about low latency audio.

Basically what was said is that they are doing a few things to improve the latency. One is the implementation of a fast mixer for OpenSL. They are trying to get the latency very low but once you get to the sub-10ms level the problems become more device dependent.

For the Galaxy Nexus with ICS latency was ~100 ms and with their changes they got it down to ~12 ms. They still want to make the latency lower than that to 10ms or lower. Not all Jelly Bean devices are showing such a dramatic improvement.

They work will not be completed with Jelly Bean, they will continue to make improvements in the next version (K).

I'm glad to hear this! I've moved to the iPad, and I am quite happy with it, but competition is great for the consumer, and I'd love to see Android more competitive in this area.

It looks like there has been some serious improvement to audio latency. That's great news.

It would be great to see Nanostudio on the new 7 inch google tablet. Hopefully soon.

Android Jelly Bean still crap for audio apps.
