Convert VOB to AAC — Free Online Converter

DVD VOB files contain multi-channel audio tracks — typically AC3 (Dolby Digital) at 192-448 kbps for stereo or 384-640 kbps for 5.1 surround, DTS at up to 1.5 Mbps, or LPCM at 1536 kbps. AAC (Advanced Audio Coding) is the modern successor to MP3, offering superior quality at equivalent bitrates and native playback on every smartphone, tablet, and computer.

Extracting audio from DVD VOBs to AAC produces compact, universally playable audio files from disc-based content. This is common for isolating movie soundtracks, pulling dialogue for subtitling work, extracting commentary tracks, and creating audio-only versions of DVD lectures or concerts.

AAC efficiently preserves audio quality from AC3 sources — at 256 kbps stereo, it is perceptually equivalent to the original 448 kbps AC3 for most listeners.
