ตัวแปลงไฟล์ออนไลน์ฟรี VOB เป็น AAC

VOB is a format for DVD files that are usually stored in the VIDEO_TS folder. VOB is based on MPEG-2 and it can contain video, audio, subtitles and other data. Each file should be less than 1 GB to be compatible with all operating systems, otherwise they will not be read.

This format was originally created as an alternative to mp3. The idea was to achieve a small file size with better sound quality. The first versions weren’t quite successful, but with the development of AAC, it became possible to store sound with less loss of quality, and with the same file sizes as that of mp3.
