It COULD have been variable bitrate MP3, THEN notched out. Either way, it's screwed, but it's not FM and I don't think it's MP3 either, unless it is VBR.

I think definitely a notch filter, but how about that blockiness above 16 KHz? How would that come in except with some lossy encoding? So I lean towards Notched/VBR. I should try that on some other shows and see if they look the same as this one.
