ตัวแปลงไฟล์ออนไลน์ฟรี VOB เป็น M4A

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 is a lossless-format (and encoding algorithm) for Apple platforms. M4A is widely used in iPod players and as a component in QuickTime media-players. The m4a codecs decoder is found in open sources - this allows third party users to open files in that format.
