JSyn can record audio from the microphone or Line level
input, process it, and play it back.
Here is a very simple recording Applet that let's you
record a couple seconds of voice and play it back.
This example is intentionally very simple to demonstrate
how to call the LineIn unit generator. A fancier Applet could put up progress
meters while recording, etc.
Note that you will be asked for permission to use the
microphone. Just click OK to enable the application to run.
Note: talking directly into an inexpensive microphone
can cause pops and thumps when you say words with "P". To prevent this
talk to a point 6 inches to the left or right of the microphone.
Check to make sure your microphone is plugged into the right jack.
Make sure that the microphone is selected as the input device in your audio control panel.
Make sure the audio input volume is turned up.
Try recording your voice with another program, like the Windows Sound Recorder.
