For a file uploaded to Telegram, I have a file_id and I can download it. But when the file is sent originally, there is an audio object available that has more metadata than the file (for example, title, performer, etc.). Is there a way to get this information again by having just the file_id?

You can use sendAudio method to send the audio to a chat and the response will contain all the attached details.
Unfortunately, it is not possible to get such information from the file_id only. No one knew what was contained in the file_id until recently when a couple of individual managed to ‘crack’ it. You can check what is in a file_id using this. So a file_id is just a representation of the location of a file on the Telegram servers which contains a little bit of information such as data center, location of file, a hashed checksum which further contains original uploader etc.
