There is a 3.9 KHz digitization artifact about 78 dB down from normal
audio level. Is this what you hear?
I suspect Jack has identified Evert's problem. The 3.9 kHz artifact should
sound exactly as Evert describes.
Maybe, maybe not. Evert, can you please make a WAV recording while the sharp
metallic audio is present? Please email me a copy of the WAV file.
