Need Audio from Your DVDs?

VOB files contain the video and audio data from DVDs, but getting just the audio out has always been a challenge. Maybe you have a concert DVD, a language learning disc, or an audiobook on DVD that you want to listen to on your phone.

Converting VOB files to AAC extracts the audio portion and gives you a compact, high-quality file that plays on virtually any modern device. AAC is the audio format used by Apple, YouTube, and most streaming services for good reason - it sounds excellent at smaller file sizes.

How to Convert VOB to AAC

  1. Upload your VOB file - Drag and drop or click to select your DVD video file
  2. Choose AAC as output - AAC is selected for optimal quality and compatibility
  3. Download your audio - Get your extracted audio file ready for any device

The entire process happens in your browser. No software to install, no technical knowledge required.

Why VOB Files Are Complicated

VOB (Video Object) files are the container format used on DVDs since 1996. They bundle video, audio, subtitles, and menu data into a single file, which is why they are typically found in the VIDEO_TS folder on DVD discs.

The problem with VOB files:

  • Large file sizes - A single VOB file can be over 1GB
  • Limited device support - Most phones and tablets cannot play VOB
  • Audio locked inside video - You cannot simply rename the file to get audio
  • Multiple audio streams - DVDs often contain different language tracks

In our testing, DVD audio typically uses AC-3 (Dolby Digital) encoding at 48kHz. Our converter extracts this audio and transcodes it to AAC while maintaining quality.

Why AAC is the Right Choice

AAC (Advanced Audio Coding) replaced MP3 as the preferred audio format for a reason. At the same bitrate, AAC delivers noticeably better audio quality. Here is how it compares:

  • Better compression - Same quality as MP3 at 20-30% smaller file size
  • Universal playback - Works on iPhone, Android, Windows, Mac, and web browsers
  • Streaming standard - YouTube, Apple Music, and Spotify all use AAC
  • Modern codec - Designed for current hardware and software

If you need an alternative, consider VOB to MP3 for maximum compatibility with older devices, or VOB to FLAC if you want lossless audio preservation.

Common Use Cases

Concert DVDs

Extract your favorite live performances to listen on the go. Convert the entire concert or just specific tracks to AAC for your music library.

Language Learning

Many language courses come on DVD. Extract the audio lessons to AAC so you can practice listening during your commute or workout.

Audiobooks and Spoken Content

Older audiobooks and educational content on DVD can be converted to AAC for convenient listening on any device.

Preserving DVD Collections

DVDs degrade over time. Extract the audio from your collection now while the discs still read properly.

Works on Any Device

Our VOB to AAC converter runs entirely in your web browser:

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

No downloads required. No account needed. Just upload, convert, and download your audio file.

Pro Tip

DVDs split content across multiple VOB files (usually 1GB each). If you want the complete audio from a DVD, convert all VTS_XX_X.VOB files in sequence, not just the first one.

Common Mistake

Trying to convert VOB files directly from a copy-protected DVD. You need to first copy the VOB files to your computer. If the files are encrypted, the conversion will fail or produce corrupted audio.

Best For

Extracting audio from concert DVDs, language learning discs, or audiobooks for listening on mobile devices. AAC gives you the best balance of quality and file size for portable listening.

Not Recommended

If you need to preserve the original audio exactly as stored on the DVD (lossless), convert to FLAC instead. AAC is a lossy format, so there is some quality reduction compared to the original DVD audio.

Frequently Asked Questions

VOB (Video Object) is the container format used on DVDs. It contains video, audio, subtitles, and navigation data bundled together. VOB files are typically found in the VIDEO_TS folder when you access a DVD's contents on a computer.

Yes. DVD audio is typically encoded in AC-3 (Dolby Digital) format. Our converter extracts this audio and converts it to AAC at high quality settings, maintaining the fidelity of the original DVD audio track.

Our converter works with unprotected VOB files that you have access to on your computer. Copy-protected DVDs encrypt their VOB files, which prevents extraction. You need an unencrypted VOB file for conversion.

Significantly smaller. A 1GB VOB file might produce an AAC audio file of around 50-100MB depending on the audio length and quality settings. You are extracting just the audio portion, which is much smaller than video.

DVDs often contain multiple audio tracks for different languages or commentary. Our converter extracts the primary audio track. If you need a specific alternate track, you may need to use desktop software that allows track selection.

Yes, both iPhone and Android devices support AAC playback natively. AAC is actually the preferred audio format for iOS devices and is fully supported on Android through the default music players.

Yes, for modern use. AAC provides better audio quality at the same bitrate as MP3, meaning smaller files with equivalent sound quality. AAC is the newer standard used by Apple Music, YouTube, and most streaming services.

Conversion time depends on the VOB file size and your internet connection for upload. A typical 1GB VOB file takes 2-5 minutes to upload and convert. The actual conversion process is quite fast once the file is uploaded.

Yes. You can upload multiple VOB files and convert them all to AAC in a batch. This is useful when processing an entire DVD that contains multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.).
