Hi,
The documentation for AudioRecord specifies that the constructor may
fail based on what the hardware supports. The format of the data will
depend on if the hardware supports it. Since the current android
emulator is like a G1 type phone, and phone systems are usually
8000hz, the hardware
I believe this is a known limitation of the emulator. There is a
feature request to allow for more sample rates, but no one is actively
working on it. The source code is available if someone wants to take
it on.

Nope. My actual G1 seems to record just fine at 11025 or 22050 hz

Dave, Yoni,
Thank you for replying.
Is this on the emulator? If so, it may be a limitation of the emulator.
Yes, I experienced the problem using the 1.5 prerelease SDK emulator.
I dont know how the G1 would behave.
Make sure you're using 16 bit samples..
I have tried pretty much ALL
you can try this code:
private static final int AUDIO_SAMPLE_FREQ = 8000;
private static final int AUDIO_BUFFER_SIZE = 20;
private AudioRecord recorder;
try
{
// init recorder
recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,
Steven,
Thank you for your reply.
I know AudioRecord works with a sample frequency of 8000Hz. In my
initial post I was asking why this frequency is the ONLY frequency
that works?!
BTW, there is no exception thrown when the initialization of
AudioRecord fails. I figured you are supposed to

Make sure you're using 16 bit samples. 8 bit samples seem to just not
work. Don't use the default anythings - actually set it to MIC,
PCM_16BIT, 11025, MONO. Then once that works you can try tweaking
other options. Also, make sure your buffer is big enough - you can use
8 matches
