Speak into the microphone "Recording my first sound file - testing the quality of sound". Any other phrase will do just as well :)
Press the "Stop" button
Play your recorded sound file to verify the recording. Then save ("File" "Save As..." menu selection) your newly created .WAV file in the "Temp" directory with a name "test1.wav"
Create one more copy of the newly created file: "File" "Save As..." - "test1optimized.wav". This is the file we will optimize using available resources.
