Okay. The window that came up on the link said "download" and there was a 3 second .mp3 clip that I was able to listen to via VLC media player.
Seemed to be three words - last being "testing". Somewhat robotic.
I opened the VLC Tools tab and experimented with Adjustments and Effects; Audio Effects in particular.
Compressor changes seemed to have the most effect. Lowered the pitch and reduced the drawl.
Made the voice sound younger and somewhat clearer.
Still in agreement with TJ hooker. Do some additional work with the recording software and reinstall if nothing seems to correct whatever alteration is being imposed. Perhaps some third party audio editor was included in some download. Buggy.
You should be able prove that source is not a physical problem by testing other audio hardware on your system or testing your audio hardware on other systems.
As for "satanic" I have always been amused, as far back as the Wizard of Oz, ("Pay no attention to the man behind the curtain." etc.) how Hollywood portrays or otherwise gives voices to gods, demons, and evildoers in general.
Would be a dead giveaway if true.
