The reason the Sciencechannel MP3 file is awkward to save in the first place is that the platform serves it as a stream rather than as a file. This page does the small amount of work that turns one into the other, and nothing else. Nothing here re-encodes, so an audio-only file exists only where Sciencechannel publishes one; where it ships audio muxed inside the video stream, that stream is what there is to take. Sciencechannel is handled by the media route, which reads the site's own rendition list before choosing anything. Some Sciencechannel URLs name a collection rather than a single item, and those return everything the collection holds.
Shortcut — stick tikt.com/ on the front of the Sciencechannel address instead of copying it here:
tikt.com/https://www.example.com/path/to/media
Use the address bar or the platform's own share button — both give a URL the extractor recognises. Point it at the single item you want, not the page around it.
Paste the URL above. The extractor asks Sciencechannel which renditions exist for that item and picks the best progressive one rather than assuming a quality.
The file arrives in the container Sciencechannel served it in, and the extractor does not rebuild it — so what you end up with is what the uploader encoded, for better or worse.
