Here's a curiosity question... has something changed in the recording/encoding/sampling of the short program, "Answers with Ken Ham"?

Reason we ask... we've noticed a slight "digital distortion/artifact" in the voice, that wasn't there before. (It started maybe a few weeks ago.)

To my ears, it sounds like a "quick/rough conversion" was done from 48K sampling down to 44.1K. (Meaning, no pre-filtering was applied to the audio before conversion.) It's like a faint, high frequency artifact is mixed with Ken's voice, in sync with it.

When I look at the spectrum display of the program, it extends all the way up to 22khz. (Which in itself seems a bit odd.) I tried applying a 15Khz "brickwall" filter, but it made no improvement.

We want to see if there is something here that we need to tweak, or if there's something "upstream" that was changed.

Thanks. :)

May all your transmitters keep transmitting, automation keep automating, listeners keep listening, and staff keep praying! :)

HAPPY NEW YEAR!!!

Willie...
