Extract Audio from Your DVD Files

VOB files are the video format found on DVDs-containing movies, concerts, lectures, and home recordings. When you need just the audio from these files, converting to MP3 extracts the soundtrack in a format that plays everywhere.

MP3 is the universal audio format. Every phone, computer, car stereo, and media player supports it. In our testing, MP3 files from DVD audio maintain excellent quality while being a fraction of the original size.

How to Convert VOB to MP3

  1. Upload your VOB file - Select the DVD video file containing the audio you want
  2. Confirm MP3 output - MP3 is already selected for maximum compatibility
  3. Download your audio - Get your extracted audio ready for any device

The entire process happens in your browser. No DVD ripping software to install, no accounts to create.

Understanding VOB Files

VOB (Video Object) is the container format used on all DVDs. When you look in the VIDEO_TS folder of any DVD, you'll find VOB files. Each file can contain multiple streams:

  • Video - MPEG-2 encoded video (480p or 576p resolution)
  • Audio - Dolby Digital (AC3), DTS, or uncompressed PCM
  • Subtitles - Multiple language subtitle tracks
  • Menus - DVD navigation and chapter information

Converting to MP3 extracts just the audio, discarding video and other data. A 4GB DVD can yield audio files under 200MB.

Why MP3 is the Best Choice

Universal Compatibility

MP3 has been the standard audio format since the 1990s. Every device made in the last 25 years plays MP3 files without additional software or codecs.

Portable File Sizes

MP3 compression makes files roughly 10 times smaller than CD audio quality. A 2-hour concert DVD produces an MP3 file you can easily share or store.

Flexible Quality Options

MP3 supports various bitrates. Higher bitrates (256-320kbps) preserve more detail from the original DVD audio, while lower bitrates create smaller files.

Common VOB to MP3 Use Cases

Concert and Music DVDs

Convert live concert recordings to listen while commuting or exercising. Extract your favorite performances without needing the video. Many concert DVDs have audio mixed specifically for the release-often better than CD versions.

Educational Content

Lectures, language courses, and documentary narration work well as audio-only. Convert educational DVDs to MP3 and learn during your commute or while doing other tasks.

Home Video Soundtracks

Family recordings often capture audio worth preserving-a relative's voice, a special event's ambiance, or music from a celebration. Extract these moments as MP3 files for easy access.

Movie Soundtracks

Some films have memorable scores or dialogue worth keeping. Extract audio for personal use, background listening, or study purposes.

Audio Quality from DVDs

DVD audio quality is higher than you might expect:

  • Dolby Digital (AC3) - Up to 640kbps, 48kHz sample rate
  • DTS - Up to 1.5Mbps, studio-quality surround sound
  • PCM - Uncompressed CD-quality audio (1.5Mbps stereo)

MP3 at 256kbps or higher preserves most of this quality for everyday listening. The difference is only noticeable on high-end audio equipment with careful listening.

Alternatives to MP3

Depending on your needs, other formats might work better:

  • VOB to WMA - If you use Windows Media Player exclusively
  • VOB to WAV - For uncompressed audio and editing purposes
  • VOB to FLAC - Lossless compression for archiving without quality loss
  • VOB to AAC - Apple devices and iTunes optimization

For most people, MP3 remains the most practical choice due to universal compatibility.

Works on Any Device

Convert VOB to MP3 directly in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android

No downloads, no installations. Upload your VOB files and get MP3 audio instantly.

Pro Tip

For concert DVDs, check for multiple audio tracks. Many concert DVDs include a stereo mix on track 1 and surround mix on track 2. The stereo mix often sounds better when converted to MP3 since it's already optimized for two-channel playback.

Common Mistake

Trying to convert encrypted VOB files from commercial DVDs. The converter will fail or produce errors. Always verify you can play the VOB file in VLC first-if VLC can't play it, the file is likely encrypted.

Best For

Extracting audio from concert DVDs, educational content, and home recordings. Perfect for creating portable audio versions of DVD content you already own for listening without the video.

Not Recommended

Don't use this for professional audio archiving where quality is critical. For archival purposes, convert to FLAC or WAV to preserve maximum quality. MP3 compression, while minimal, does discard some audio data.

Frequently Asked Questions

VOB (Video Object) is the file format used on DVDs. It contains video, audio, subtitles, and menu data. VOB files are found in the VIDEO_TS folder of any DVD disc. They use MPEG-2 video compression and support multiple audio formats including Dolby Digital and DTS.

This converter works with unprotected VOB files only. Commercial DVDs often have CSS encryption that prevents direct file access. Home recordings and unencrypted content convert without issues. For protected discs, you'd need separate decryption tools first.

DVD audio is typically high quality (48kHz, up to 640kbps for Dolby Digital). Converting to MP3 at 192-320kbps preserves most of this quality. For casual listening, you won't notice a difference from the original DVD audio.

The primary audio track is extracted by default. DVDs with multiple languages have several audio streams-track 1 (usually the main language) is what gets converted. Director commentary and alternate tracks require separate extraction.

Much smaller than the source VOB. A typical 1GB VOB file (about 30 minutes of DVD video) produces an MP3 around 30-50MB at high quality. File size depends on audio length and chosen bitrate.

Most phones don't support VOB playback natively. You'd need apps like VLC. Converting to MP3 creates a file any music app can play, and the file size is much more practical for mobile storage.

MP3 output is stereo. Multi-channel DVD audio (5.1 surround) is downmixed to two channels during conversion. The music and dialogue remain clear, but the spatial surround effect is lost.

DVDs split content across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.), typically capped at 1GB each. The main movie content is usually in the numbered VTS files. Menu and special features are in separate VOB files.

Both produce similar quality at equivalent bitrates. MP3 has wider compatibility with older devices and car stereos. AAC is slightly more efficient and preferred for Apple devices. For universal playback, MP3 is the safer choice.
