Hi Ted,
the 'problem' could have different causes. I think it's the windows-setting for your soundcard in your computer computer.
The audio-recorder from Technics is the most basic-program they gave us . There are no setting-features in it. I don't know what version of Windows you have, but I advise you to use for instand the windows-recorder. (or another 'free' audio-recorder). With these programs you can easier change the sound-input and output settings.
P.S. even you could 'recover' your original waves with mostly of these programs to a higher lever of sound.
Succes, greetings
Cees
