Hello,

Here is a link for how to record a audio.

http://wiki.forum.nokia.com/index.ph...ce_using_MMAPI


Here is a code for audio capture for 5 sec

try {
// Create a Player that captures live audio.
Player p = Manager.createPlayer("capture://audio");
p.realize();
// Get the RecordControl, set the record stream,
// start the Player and record for 5 seconds.
RecordControl rc = (RecordControl)p.getControl("RecordControl");
ByteArrayOutputStream output = new ByteArrayOutputStream();
rc.setRecordStream(output);
rc.startRecord();
p.start();
Thread.currentThread().sleep(5000);
rc.commit();
p.close();
} catch (IOException ioe) {
} catch (MediaException me) {
} catch (InterruptedException ie) { }


Hope this helps you

Hello,

javax.microedition media.MedisException:Symbian OS error:-1 means

"Unable to find the specified object”

I also tried to run the midlet I got different error

Prefetch -5.

Chetan, check in which sound format you recorded and verify whether that format supported.

Hi,
When I run the the midlet provided on the link "http://www.hcilab.org/documents/tutorials/AudioTest/ "on mobile phone it runs well,But the problem is ,when I run this, it asks "Allow application voiceRecord midlet suite to use audio application"? then i need to select YES and proceed .But I dont need this to come, when i run the application it should directly go to the application and start recording..What are the settings to be changed in order to skip the above step..?:

pls help me to solve this..

thanks

when you run application it asks "Allow application voiceRecord midlet suite to use audio application"? because of security reason so for this you sign your application.
