yeah.
emulator 1.5 is ok but 1.6 is not.
ironic, real phone 1.6 is ok but 1.5 is not.
that is what i told u before.

In this case no news = bad news ...
Based on Mario´s post and the possibilities I could think about in the
last days I have modified the code trying to isolate the issues like
calling blocking methods and as a consequence loosing part of the
audio stream, having buffer overflows, etc, as this
Nope,
I´ve paid attention to see if GC was being called, but nothing shows
up on LogCat.
Well, I´ve found some posts on the internet about using AudioRecord´s
native implementation. Isn´t it supported anymore?
I still can´t believe we are spending so much time on something that
should be plug
i heard that too. but some google folk seemed discouraging use of the
stuff.

Installing ubuntu 9.1 on my machine.
I will try using linux to develop as I think it will be less confusing
to develop using NDK.
Hehe: I was thinking about trying to get an answer from someone from
Google tomorrow at irc. Have you ever tried it?
Won´t anyone who is actually using AudioRecord
no, i havent, because my app runs ok on g1 with 1.6 firmware. it just
runs weird on 1.6 emulator. so i am 90% happy already.
btw, my app does not record and play audio at the same time, but it
encodes audio with speex, which should take overhead no less than
playback, i guess.
anyway, i wish you
Hi there,
not sure whether i can help but you stated that you couldn't find
anywhere that AudioTrack.play() (which should probably read
AudioTrack.write()) does not block. Well, it does. And if you do the
following in your thread:
AudioRecord.read(sampels)
AudioTrack.write(samples)
i can
Thanks Mario
Yes, I wrote it wrong ... should have been AudioTrack.write().
That idea came to my mind a couple of hours ago. Since AudioTrack set
as stream will only start playing as the buffer gets full, write()
could block if the buffer is still full.
To test it, I have created AudioTrack
Thanks for your answer Mario!

News, but no good news...
I´ve tried the source code above on another machine running the sdk
2.1, an AVD with default parameters plus audio record and audio
playback capabilities, another operational system (linux), etc.
The results? the same we had before audio delay (long delay),

Using the NDK native audio interfaces should solve this problem?

if you find any native audio interfaces in NDK, please share it with
me first :)
for your issue, did you check GC? that is, around the time when you
see buffer overflow msgs, does GC happen too?

It is the problem with your driver which creates this chopping
effect.It is not able to read the data properly and if you check your
kernel messages there would be a buffer overrun message.This happens
because Linux is not RTOS and audio is running in real time.
What you are recording is noise
Thanks for your answers ...
Well, since the same source code works on your computer and not on
mine, I think the chopping problem is on my emulator. My computer is
not as good as yours but it´s a Turion X2 notebook with 2gb ram, so if

Well, just to try I´ve downloaded the SDK 1.6 (v. 4), created a new
AVD based on that and then tried the source code from the first post
in two different situations:
- App compiled using SDK 1.6 on an AVD running 1.6
- App compiled using SDK 1.6 on an AVD running 2.1
Had exactly the same result

Audio chopping also?
Could you please test the code above?
I´ve checked and AudioRecord.read() returns a value equal to my buffer
size. Based on that I understand that AudioRecord.read() blocks the
execution, waits for the buffer to get a number of samples at least
equal to the buffer size and
no chopping, likely because my computer (Core2 E8400) is lightening
fast.
my AudioRecord.read() returns a value equal to my buffer size, too.
however, it returns recorded samples in a speed faster than 8khz,
which makes later playback sound like my voice is slowed.
again, the same code works
