ตัวแปลงไฟล์ออนไลน์ฟรี VOB เป็น OPUS

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.

Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end ARM3 processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.
