I am successfully able to record using the mike of the blackberry through code.However the files that are being made which are .amr files.after a recording of say 1min a file of 132kb is made.which is quite huge in j2me standards
Could dere be sum other encryption type like .amr which would make lighter files.What can i do so dat a large no. of small files are made instead of a single heavy file.
private static final long mtime = 100000;//records for 1min
RecordControl rc;
byte[] data;
public void run()
{
// TODO Auto-generated method stub
try
{ Player p = Manager.createPlayer("capture://audio?encoding=amr"); // Player p set to capture audio here
p.realize();
rc = (RecordControl)p.getControl("RecordControl");
ByteArrayOutputStream os = new ByteArrayOutputStream();
rc.setRecordStream(os);
/**FileConnection fc = (FileConnection)Connector.open("file:///store/home/user/RecordedFiles/audio1.amr");
//if(!fc.exists())
{
fc.create();
}
DataOutputStream ot= fc.openDataOutputStream();**/
//rc.setRecordStream(ot);
rc.startRecord();//starts the recording
p.start();
Thread.sleep(MikeApp.mtime);
rc.commit();
p.close();
data = os.toByteArray();
saveRecordedFile(data);
if (p != null)
{
p.stop();
p.close();
p = null;
}
}
