Converting Android Thumbnail Database Format directly to MP3 Audio Files (.thumbdata3 to .mp3 conversion) is unfortunately not possible. 

You can find such THUMBDATA3 database files on SD cards of Android devices. They neither contain documents, nor any other multimedia data, which is why you cannot simply extract, export or convert them to other formats, such as MP3.

Simply put, it is impossible to convert THUMBDATA3 to MP3 directly.
Thus, there is no so-called thumbdata3 to mp3 converter or a free online thumbdata3 to mp3 converter to be found.
