Understand VOB and AC3 Format
VOB is a multimedia container format. It is the primary container format for DVD video discs, capable of holding MPEG-2 video, subtitle tracks, menu data, and audio streams (AC3, DTS, PCM). VOB format can be played on DVD players and media players such as VLC. However, most new mobile phones and smart TVs do not support native playback.
AC3, also known as Audio Codec 3, is a lossy audio compression technology developed by Dolby Laboratories. It is commonly used in DVDs, Blu-ray discs, and digital televisions. Furthermore, AC3 supports multiple channels, up to 5.1 channels (left channel, right channel, center channel, two rear channels, and one subwoofer channel). Therefore, it is also widely used in cinemas to provide an immersive sound experience.
Why Convert VOB to AC3
As mentioned above, VOB files can contain AC3 audio. If you want the audio included in the VOB to be playable on more modern devices, such as mobile phones, tablets, and smart TVs, you can extract the AC3 audio tracks embedded in a VOB file. Next, I will recommend 2 tools that support VOB to AC3 conversion.
