Fast Transcriber derives an accepted media type from the filename and supplied or stored Content-Type. Unsupported media returns 415 unsupported_type; an empty stored object returns 400 empty_upload.
Send honest metadata
Changing an extension does not turn an unsupported payload into media. Supply the original filename and the MIME type reported by the file source.
