Hello,

We need to test AAudio and Oboe on various devices and various versions of
Android. So if YOU have published an app that uses Oboe, or AAudio
directly, then please reply and include a link to your app in the Play
Store.

It will help us catch problems before release. And it will help you because
releases will be less likely to break your app.

Thanks,
Phil Burk

Hi Phil,

n-Track Studio supports AAudio directly. It currently defaults to OpenSLES
though (I got bitten by the AAudio bug in 8.0), but AAudio can be selected
in the Settings box.
Here's the link:

Cheers,

It was a random crash in Java code:
https://github.com/google/oboe/issues/40

Very bad... the stack was completely unrelated to anything I was doing.
It took me quite a while to figure it out.

Thanks Flavio. We'll add that to the list.
Post by Glenn Kasten
You mentioned "the AAudio bug in 8.0" ..
There was a reference counting bug in PlayerBase that affected AAudio.
Fixed in 8.1.
Oboe will use AAudio for 8.1 and above. Otherwise it uses OpenSL ES.

Hi Guys,
I have project with pitch shifting (resampling with wsola), It implemets on
android NDK.
Since duration of pitch is ~20ms I can't use system recommended parameters
for fastpath. for example, for my device: SampleRate:48Khz and buffer size
240 samples. That means, duration time is 5ms (< pitch duration = 20ms).
Can I change fastpath ?
Can the resampling help ? I need to do processing in 8Khz.

Thanks,
Alex

Your question is unrelated to the subject of this thread, which is "need

When you want to start a new topic, please do not reply to an existing

Please start a new thread by writing directly to the group with a relevant
