How to change media data for mp3 file?

Question

WordPress

How can I update these fields for similar post (mp3 file) via wordpress api?
Of particular interest are the last two meta fields.

Answer 1

It is not entirely clear how these fields were obtained. But the general principle is this - you register a new route in the Rest API, to which you send the id of the entry and the parameters you want to update. The route should call a function to which you pass these parameters, and then use update_post_meta to replace them with a new value.
