rate to change by 9% under certain condition. Those conditions are:
1. The HDMI video output to a TV monitor is connected.

My application uses AudioTrack in streaming mode and AudioRecord

My problem is that I start them at the same time, but it is not

Hi All,
I used AudioRecord on emulator and phone. I found that AudioRecord is
not working on phone:
1> the min-buffer-size on simulator is much smaller than phone
2> The audio data I read from phone is all zero.

Hi,
Android's AudioFlinger does the job of downsampling to 8khz irrespective
of whatever be the top level applications sampling rate setting.
AudioFlinger will down sample to 8khz and record. You may try another method
of recording using arecord utility of alsa.
#alsa_arecord -f 16000 -c 2 -Dhw
what is the build fingerprint on your device ?

from 1.5 to 2.2).

Is there a way to disable AGC and noise suppression in the AudioRecord

Hello Android Developers!
My Android Java Application needs to record audio data into the RAM
and process it. This is why I use the class "AudioRecord" and not the
"MediaRecorder" (records only to file).
Till now, I used a busy loop polling with "read()" for the audio data.

knee-jerk answer: because the individual samples
are 16 bits wide, and by reading just a byte each
time, you're only getting half the sample.
Any idea why reading bytes from AudioRecord would cause an error while
reading shorts would not? The sound comes through great with short
