Extract Audio from Your DVDs
VOB files contain the audio and video data from DVDs, but getting just the audio out can be frustrating. You have concert recordings, movie soundtracks, or spoken content on disc, and you want to listen without the video.
Converting VOB files to OPUS extracts just the audio track and compresses it into a modern, efficient format. OPUS delivers excellent sound quality at much smaller file sizes than older formats like MP3.
How to Convert VOB to OPUS
- Upload your VOB file - Drag and drop or select from your device
- Select OPUS as output - Choose the OPUS format for modern, efficient audio
- Download your audio - Get your extracted audio in seconds
No software to install, no account required. Just upload and convert.
Why Choose OPUS Over Other Formats?
OPUS is the modern choice for audio compression. Developed by the Xiph.Org Foundation and standardized by the IETF in 2012, it outperforms older codecs in almost every measurable way:
- Better quality at lower bitrates - OPUS at 64 kbps sounds comparable to MP3 at 128 kbps
- Smaller files - Save storage space without sacrificing quality
- Open and royalty-free - No licensing fees or restrictions
- Wide support - Works in all major browsers and most media players
In our testing, a typical 5-minute audio track from a DVD converts to roughly 2-3 MB in OPUS format at transparent quality, compared to 5-6 MB for equivalent MP3 quality.
Common Use Cases
Concert DVDs and Live Recordings
Extract live performances from concert DVDs to listen on your phone or portable player. OPUS keeps the audio quality high while keeping files manageable.
Movie Soundtracks and Dialogue
Pull the audio from your favorite films. Great for language learning, audiobook-style listening, or just enjoying Hans Zimmer's scores on the go.
Educational and Training Content
Convert instructional DVDs to audio-only format. Listen to lectures and training materials during your commute without needing to watch video.
VOB Audio Quality Explained
DVD VOB files typically contain audio encoded in AC3 (Dolby Digital) or PCM format at 48 kHz sample rate. AC3 tracks usually range from 192 to 448 kbps, while PCM can be uncompressed at over 1,500 kbps.
When converting to OPUS, this audio gets re-encoded. OPUS at 128 kbps preserves virtually all audible detail from AC3 sources. For PCM or high-bitrate AC3, you might choose 160-192 kbps OPUS to be safe, though most listeners cannot distinguish the difference from 128 kbps.
When to Use a Different Format
OPUS is excellent for most scenarios, but consider alternatives in specific cases:
- Older devices - Some car stereos and older MP3 players do not support OPUS. Try VOB to MP3 for maximum compatibility.
- Apple ecosystem - If you primarily use iTunes and older iPhones, VOB to AAC integrates more seamlessly.
- Archival purposes - For lossless preservation, consider VOB to FLAC if file size is not a concern.
For streaming, podcasts, and general listening on modern devices, OPUS remains the best choice.
