Audio Capture Configuration Question

I am trying to sample the microphone using a recordStream. How do I control the rate, bits, unsigned, etc...

If I use:
p = Manager.createPlayer("capture://audio");
Under Ktools everything slows to a trickle and takes about 5 seconds to record 20 miiliseconds worth of data, then i get aboput 80,000 bytes of data that appears to be 16 bits
in the Manager class description
http://www.cs.kent.ac.uk/teaching/03/modules/CO/6/25/doc/LOC/MMA/javax/microedition/media/Manager.html
it says I can do things like:
Manager.createPlayer("capture://audio?bits=8");
When I do this I get:
Cannot create a DataSource for: capture://audio?bits=8
How can I control the sample rate, # of bits etc...?
Thank You

What WTK do you use? I got the same problem with J2ME WTK 2.1 but with the version 2.0 it works , for example :

Player player = Manager.createPlayer("capture://audio? rate=8000&bits=8&Channels=1");

I've not used wtk2.1, but I've heard from other forums, wtk2.1 requires a seperated thread to do what you wanted to do.

Let us know if this helps.

My capturing routine is already running in a separate thread. Could you please explain more detailed what do you mean or give me a link where i can find more information about this problem (which forum?)

thanks in advance

Sorry! It was ChinaJavaWorld.net and in Chinese. And worse than that, the forums are closed for space problems recently.

Hopefully, they will open again soon.
