Why Extract Audio from DVD to AIFF?

VOB files contain the audio and video data from DVDs, often with high-quality soundtracks encoded in AC-3, DTS, or even uncompressed PCM. If you need that audio for editing, sampling, or archiving, AIFF is the ideal destination format.

AIFF (Audio Interchange File Format) stores audio without compression, preserving every detail from the original VOB files. It's the standard for professional audio work on Mac and works seamlessly with Logic Pro, Pro Tools, GarageBand, and other DAWs.

How to Convert VOB to AIFF

  1. Upload your VOB file - Drag and drop or click to select your DVD video file
  2. Select AIFF as output - Choose AIFF for uncompressed, professional-quality audio
  3. Download your audio - Get your extracted AIFF file ready for editing

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

VOB vs AIFF: Understanding the Formats

VOB is a container format that holds video, audio, subtitles, and menu data from DVDs. The audio inside can vary widely:

  • AC-3 (Dolby Digital) - Most common, compressed 5.1 surround sound
  • DTS - Higher bitrate surround sound compression
  • LPCM - Uncompressed stereo, often on music DVDs
  • MPEG Audio - Compressed stereo, used in some regions

AIFF, by contrast, is a pure audio format. It stores uncompressed PCM audio at full quality - typically 16-bit or 24-bit at 44.1kHz or 48kHz. In our testing, AIFF files extracted from DVDs maintain excellent fidelity even when the source was compressed AC-3.

When to Use AIFF Instead of MP3

AIFF makes sense when quality matters more than file size:

  • Audio editing - Uncompressed files don't degrade when you edit and re-export
  • Music production - Sample DVD audio without compression artifacts
  • Archiving - Preserve the original audio quality indefinitely
  • Mac workflows - AIFF integrates natively with macOS and Apple apps

If you just need the audio for casual listening, VOB to MP3 gives you smaller files that play everywhere. For professional work, AIFF is the better choice.

Common Use Cases

Film Score Extraction

Got a DVD with a soundtrack you need for a video project? Extract the audio as AIFF to get clean, editable audio files. This is common for editors working with licensed content or their own productions.

Music DVD Archiving

Concert DVDs and music videos often have high-quality audio. Converting to AIFF preserves that quality for your music library or further production work.

Audio Restoration

Old recordings released on DVD can be extracted and restored. AIFF's uncompressed format means you're not fighting compression artifacts during cleanup.

Alternative Formats to Consider

AIFF isn't always the right choice. Here are alternatives:

  • VOB to WAV - Same uncompressed quality, slightly better Windows compatibility
  • VOB to MP3 - Much smaller files, works everywhere, fine for casual listening
  • VOB to FLAC - Lossless compression, half the file size of AIFF with identical quality

Choose AIFF specifically when you're working in Apple's ecosystem or your software prefers it.

Works in Any Browser

Convert VOB to AIFF directly in your web browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • No plugins or downloads required

Processing happens locally in your browser, so your files stay private.

Pro Tip

When extracting audio from DVDs for music production, check if the DVD has LPCM audio tracks - these are already uncompressed and convert to AIFF without any quality loss. Concert and music DVDs often use LPCM.

Common Mistake

Converting to AIFF when you only need the audio for listening. AIFF files are 10x larger than MP3 with no audible difference for casual playback. Use AIFF only when you need to edit the audio.

Best For

Professional audio editors and musicians who need to extract DVD soundtracks for sampling, remixing, or post-production work in Logic Pro, Pro Tools, or similar DAWs.

Not Recommended

Not ideal if you just want to listen to DVD audio on your phone or in your car. Use MP3 instead for portable listening - files will be much smaller and play everywhere.

Frequently Asked Questions

VOB (Video Object) is the main file format used on DVDs. It contains video, audio, subtitles, and navigation data. VOB files are typically found in the VIDEO_TS folder of a DVD and use MPEG-2 video with AC-3 or DTS audio.

AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple. It stores audio at full quality without any compression, making it ideal for professional editing and music production. AIFF files are larger than MP3 but preserve complete audio fidelity.

Yes, AIFF preserves full audio quality. If the DVD audio was compressed (AC-3 or DTS), you get that quality in an editable format. If the DVD had uncompressed LPCM audio, you get a bit-perfect copy.

AIFF files are roughly 10MB per minute of stereo audio at CD quality (16-bit, 44.1kHz). A 2-hour movie soundtrack would be approximately 1.2GB. For smaller files with the same quality, consider FLAC instead.

Our converter works with standard VOB files. If your DVD has copy protection, you may need to use other tools first to create unprotected VOB files before conversion.

Both are uncompressed audio formats with identical quality. AIFF was developed by Apple and works best on Mac. WAV was developed by Microsoft and is more common on Windows. For most editing software, either works fine.

The converter extracts all audio from the VOB file. To get a specific portion, convert the full file first, then use audio editing software to trim it to the section you need.

The converter extracts the primary audio track from the VOB file. DVDs with multiple audio tracks (like different languages) store these in separate streams - you'll get the main audio track.

Choose AIFF when you plan to edit the audio or need maximum quality. MP3 is compressed and loses some detail. AIFF is uncompressed, so you can edit, process, and re-export without quality loss. For simple playback, MP3 is fine.
