Hi, I am doing a simple app to record a wav file. In my codes, I use
onPeriodicNotification function (wait for notification to write to
file). However, this function is never called.
Please help me. Below is my code regarding this function.
private AudioRecord.OnRecordPositionUpdateListener updateListener =
new AudioRecord.OnRecordPositionUpdateListener()
{
public void onPeriodicNotification(AudioRecord recorder)
{
System.out.println("start write to file()");
audioRecorder.read(buffer, 0, buffer.length); // Fill
buffer
try
{
randomAccessWriter.write(buffer); // Write
buffer to file
payloadSize += buffer.length;
if (bSamples == 16)
{
for (int i=0; i<buffer.length/2; i++)
{ // 16bit sample size
short curSample =
getShort(buffer[i*2], buffer[i*2+1]);
if (curSample > cAmplitude)
{ // Check amplitude
cAmplitude = curSample;
}
}
}
else
{ // 8bit sample size
for (int i=0; i<buffer.length; i++)
{
if (buffer[i] > cAmplitude)
{ // Check amplitude
cAmplitude = buffer[i];
}
}
}
}
catch (IOException e)
{
Log.e(ExtAudioRecorder.class.getName(), "Error
occured in
updateListener, recording is aborted");
//stop();
}
}
public void onMarkerReached(AudioRecord recorder)
{
// NOT USED
}
};
