I would like to record an audioclip of 8 seconds, save it to a file on the mobile phone and send it to an apache server of mine, which uses php. How do I achieve that, is there a tutorial for this procedure?

Regards

Hi
To record and save aduio:

public void recordAudio() {
try {

ByteArrayOutputStream output = null;
player = Manager.createPlayer("capture://audio");
player.realize();
rc = (RecordControl) player.getControl("RecordControl");
output = new ByteArrayOutputStream();
rc.setRecordStream(output);
rc.startRecord();
player.start();
} catch (Exception e) {
e.printStackTrace();
}
}

public void stopRecord()
{
try {
rc.commit();
player.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
For sending audio to server please refer nokia wiki. if not available tell me i will give you

for save the recording to filesystem and upload to server..

after commit the recording..

copy the data(bytes of bytearrayoutputstream) to byte array
byte [] data = baos.tobytearray();

copy the above data to another byte array
byte[] newdata = new byte(data.length);
copy the whole data to newdata byte by byte..

write to filesystem..
FileConnection conn = (FileConnection) Connector.open("file:///E:/testing.3gp",Connector.WRITE);
conn.create();
OutputStream out = conn.openOutputStream();
out.write(data);
close the connection and streams..


for upload to server

public synchronized void run() {
///// Define a new Http Connection
HttpConnection httpCon = null;
OutputStream dos=null;
InputStream is = null;
try {
/// Opening Http Connection
httpCon = (HttpConnection) Connector.open(url,Connector.READ_WRITE,false);

if(data!=null)
{

httpCon.setRequestMethod(HttpConnection.POST);
httpCon.setRequestProperty("Content-Length",""+data.length);
/// Open a output stream to write data
dos=httpCon.openOutputStream();
/// write data to output stream
dos.write(newdata);
dos.flush();
}

/// check for Server response code
int responseCode = httpCon.getResponseCode();

if (responseCode != HttpConnection.HTTP_OK) {
throw new IOException("Http Response Code:" + responseCode);
}


is = httpCon.openInputStream();

/**
read return data from server
*/
} catch (IOException ex) {
System.out.println("IOException");
ex.printStackTrace();
} catch(SecurityException sex){
System.out.println("Security Exception");
sex.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
} catch (OutOfMemoryError oomer) {
System.out.println("Out OF Memory Exception");
oomer.printStackTrace();

} finally {
try {
is.close();
if(dos!=null)
dos.close();
httpCon.close();

} catch (Exception ex) {
ex.printStackTrace();
}
}
}

check and reply..

Thanks. Will use it.

A question which may be potentially interesting to people looking to accomplish the same: why is it in the standard Sun J2ME simulator, the resulting wave file is incompatible to most standard players (Windows Media Player, etc.)?

I tried fiddling with the bitrate, endian, signed, but couldn't get the right combination!

Eventually I had to give it up and switch to AMR, then convert it on the server... Not the most elegant solution.

Any hints how to make the wave output more standard?
