[LAU] An Unusual artifact in a Recording?

[Chime Hart]

Hi All: I guess I may have been on this list in 2015. Have no idea if its still 
active?
I ripped an audio stream of CNN from tunein during an Impeachment Senate Trial 
this year. Commercials sound quite good, but when CNN anchors as well as Seante 
audio are playing, it has a sound of a jerking tape. When I tried looking up 
this type of issue, it mentions avidemux to fixit. I wrote an author of that 
program, who says I need to examin fps through mpv. So-far we are not making 
progress. Can any1 please suggest any tools, especially commandline Debian 
which would correct these audio glitches? If any1 wanted to hear any of these 3 
recording, I could certainly upload to my web-site, but they range from 6-13 
hours. Thanks so much in advance
