Need Audio from Your DVD Files?

VOB files contain the video and audio from DVDs, but getting just the audio out can be frustrating. Most media players won't let you extract tracks, and specialized software often comes with a learning curve.

Converting VOB to WAV extracts the audio in uncompressed format, preserving every detail from the original DVD. Whether you need dialogue, music, or sound effects, WAV gives you the highest quality audio available from your VOB files.

How to Convert VOB to WAV

  1. Upload your VOB file - Drag and drop or click to select your DVD video file
  2. Choose WAV as output - Select uncompressed WAV for maximum audio quality
  3. Download your audio - Get the extracted audio track instantly

No software installation required. The conversion happens right in your browser.

Why Convert VOB to WAV?

VOB (Video Object) is the container format used on DVDs. It stores multiplexed audio, video, and subtitle streams together. WAV (Waveform Audio) is an uncompressed audio format that preserves the original sound quality without any lossy compression.

Key reasons to extract audio as WAV:

  • Lossless quality - WAV preserves the exact audio from your DVD without re-encoding artifacts
  • Editing flexibility - Audio editors like Audacity work best with uncompressed WAV files
  • Universal compatibility - WAV plays on virtually every audio application and device
  • Master archive - Keep a pristine copy before converting to compressed formats

In our testing, extracting DVD audio directly to WAV maintains the original 48kHz/16-bit quality typical of DVD audio tracks.

Common Use Cases

Archiving DVD Collections

If you have DVDs with music performances, concerts, or spoken word content, extracting the audio lets you preserve it digitally. WAV ensures no quality is lost in the process.

Audio Editing Projects

Video editors and podcasters often need audio clips from DVD sources. WAV provides the cleanest starting point for further processing without generation loss.

Creating Music Samples

Musicians and producers extract audio from DVDs to sample dialogue, sound effects, or rare recordings. Uncompressed WAV is essential for professional sampling workflows.

VOB vs WAV: Format Comparison

Understanding the technical differences helps you know what to expect:

  • VOB - Container format holding MPEG-2 video and audio (AC3, PCM, or DTS). File sizes typically 1GB per hour of video
  • WAV - Pure audio format, uncompressed PCM. About 10MB per minute for CD-quality stereo

When we extract audio from a 1GB VOB file, the resulting WAV is typically 50-100MB depending on the audio duration and original format.

Alternative Audio Formats

WAV provides maximum quality but creates large files. Consider these alternatives for different needs:

  • VOB to MP3 - Smaller files (about 1MB per minute) for portable listening
  • VOB to FLAC - Lossless compression, files 50-60% smaller than WAV
  • VOB to AAC - Efficient compression for Apple devices and streaming

For editing and archival, WAV remains the best choice. Convert to compressed formats afterward if storage is a concern.

Works on Any Device

Our converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • Tablets and modern smartphones

No plugins or downloads needed. Your VOB files are processed locally for privacy.

Pro Tip

DVDs often contain multiple audio tracks (different languages, commentary). If you need a specific track, check your VOB file's audio streams. Our converter extracts the primary audio by default, which is usually the main language track.

Common Mistake

Converting directly to MP3 when you plan to edit the audio later. Always extract to WAV first, do your editing, then convert to compressed format. Each MP3 conversion degrades quality.

Best For

Extracting audio from DVD collections for editing, sampling, or creating a lossless audio archive. Ideal when you need the highest possible quality from your DVD source.

Not Recommended

If you just want to listen to DVD audio on your phone or portable player, WAV files are unnecessarily large. Convert to MP3 or AAC instead for everyday listening.

Frequently Asked Questions

VOB (Video Object) is the container format used on DVDs. It contains multiplexed video, audio, and subtitle streams stored in the VIDEO_TS folder of a DVD. VOB files use MPEG-2 video encoding and typically AC3 or PCM audio.

No. WAV is an uncompressed format that preserves the original audio quality from the VOB file. You get the exact same audio data without any lossy compression artifacts.

WAV files are about 10MB per minute for stereo CD-quality audio (44.1kHz/16-bit). DVD audio at 48kHz creates slightly larger files. A 2-hour movie's audio track would be approximately 1.2GB as uncompressed WAV.

Our converter works with unencrypted VOB files. If your VOB files are from a copy-protected DVD, you'll need to decrypt them first using appropriate software before conversion.

Most DVDs use Dolby Digital (AC3) for audio, which is lossy compressed at 448kbps. Some DVDs include PCM audio tracks which are uncompressed. Our converter extracts whichever audio stream is present.

Both preserve identical audio quality. WAV is more universally compatible and simpler, while FLAC saves about 40-50% storage space through lossless compression. For editing, WAV is preferred. For long-term storage, FLAC is more efficient.

Yes. Upload multiple VOB files and convert them all to WAV in a single batch. This is useful when extracting audio from an entire DVD which typically contains multiple VOB files.

VOB files contain video, audio, and subtitles combined. When you extract just the audio, you're getting only a fraction of the original data. Video comprises about 90% of a typical VOB file's size.

The output depends on your source. If the DVD has 5.1 surround audio, the WAV will contain those channels. Standard stereo DVDs produce stereo WAV files. The original channel layout is preserved.
