the downloading part is actually really simple. cURL, wget, or BSD’s ftp command can do it. even yt-dlp works. the complicated part is finding the audio file enclosure. alot of people hide it these days which is retarded. i use a command line feed viewer called newsraft to reveal the file URLs. but again, i had to spend an hour or two reading the man page to figure out how to use it. that time factor again.
