Before running this programs be sure to have the Sound Blaster 16 mixer
correctly configured:

   - Select microphone recording (you can choose other source if
     you prefer). Adjust recording level, and so on.

   - Disable microphone (or whatever you select) monitoring: You must
     not hear the microphone signal throught yor speakers.

   - Adjust wave/voice playback volume, and master volume.

It is better if you use headphones instead of loudspeakers, to avoid
microphone/speakers coupling, and to get a better feeling.
