Sound recording

[Jamel Balti]

Hi all.
Happy to come back to the best place for java. I haven't use Java for a little while. If any body have any idea where I could find a solid open source code for an Applet to capture and upload sound file.
Cheers

Hi all,
I am looking for the same topic, I have found some code on internet but I cannot make it work.
Is there anyone kind enough to give me some direction or better, a working example? I promise I'll send a good italian bottle of wine!

You gave us all this code but you failed to say what is wrong with it.
Working with JMS is non-trivial. Have you tried to make a simple application that records sound a local file? A small app that uploads a file to a server? Try to make your problems smaller and simpler and they will be easier to solve.

[pranita jadhav]

i have java code for record sound now i need to compare new speech from mike with recorded sound
can any one help me about this code
