VOB to WAV Converter

How to Convert VOB to WAV Online

1. Upload Your VOB File: Drag and drop or click "+ Add Files" to select VOB files from a ripped DVD's VIDEO_TS folder. Batch upload is supported — queue multiple VTS_01_1.VOB, VTS_01_2.VOB segments and process them in one pass.
2. Pick Audio Channel and Sample Rate: Default is "Original" — the audio track from the VOB is decoded straight to uncompressed PCM in WAV. Switch Audio Channel to "Mono" to halve file size for spoken-word DVDs (audiobooks, lectures, commentary tracks) or keep "Stereo"/"Original" for music and surround mixes. Set Audio Sample Rate to "44100Hz" if your target is CD-quality archival, "48000Hz" to keep the DVD's native rate untouched, or downsample to "22050Hz"/"16000Hz" for transcription workflows.
3. Trim the Section You Need (Optional): Use the Trim control to set a start time and duration in HH:MM:SS.ms format. This is the fastest way to pull a single song, a chapter of dialogue, or a director's commentary segment without exporting the entire DVD title.
4. Convert and Download: Click "Convert". Files process on our servers and download as standard .wav. No sign-up, no watermark, no quality degradation beyond the lossless PCM re-encode.

Why Convert VOB to WAV?

VOB (Video Object) is the MPEG program stream container that DVD-Video discs use to hold MPEG-2 video, audio (most commonly AC-3, sometimes LPCM, MP2, or DTS), and subtitle streams. WAV (Waveform Audio File Format) is the uncompressed PCM container Microsoft and IBM defined in 1991 — it's still the de-facto interchange format for editors, samplers, and broadcast tools because every DAW, NLE, and forensic tool reads it without question.

Extracting the audio track from a VOB and saving it as WAV is the right move when you need:

• Lossless masters for editing in Audacity, Reaper, Pro Tools, or Logic — WAV's PCM payload is bit-identical to what the DAW would import anyway, so there's no transcoding penalty when you move into a session.
• Audio commentary, audiobook, or lecture tracks from a DVD — pull the spoken-word stream out once, then keep working with a single audio file instead of seeking through a multi-gigabyte VOB.
• Music DVDs and concert footage — concert DVDs from the early 2000s often carry LPCM 48 kHz/16-bit or AC-3 5.1 audio that's higher quality than the YouTube rip of the same show; WAV preserves it.
• Restoration and noise-reduction workflows — tools like iZotope RX want lossless WAV input; feeding them AC-3 means they decode it first anyway.
• CD authoring — burning a Red Book audio CD requires 44.1 kHz/16-bit stereo PCM, exactly what WAV stores by default.
• Archival before re-encoding — keep a WAV master, then derive MP3, AAC, or Opus copies from it without compounding lossy artifacts.

You can also go the lossy-compressed route with VOB to MP3 or VOB to AAC if file size matters more than fidelity, or keep things lossless-compressed with VOB to FLAC (about half the size of WAV, bit-identical on decode). If you only need to clip a chapter first, Trim VOB lets you cut before converting.

Frequently Asked Questions

My DVD is copy-protected — will this still work?

No. VOB files on commercially pressed DVDs are typically encrypted with CSS (Content Scramble System), introduced in 1996 to deter unauthorized copying. Browsers and online converters cannot decrypt CSS — you need a desktop DVD-ripping tool (HandBrake with libdvdcss, MakeMKV) to produce a decrypted VOB or MKV first, then upload that file here. Personal DVDs, camcorder DVDs, and home-burned discs are not CSS-protected and convert directly.

Why is my WAV file so much larger than the VOB's audio track?

Because WAV is uncompressed PCM. A stereo 48 kHz / 16-bit WAV runs at about 1.41 Mbps — roughly 10 MB per minute. The original AC-3 track inside the VOB was likely 192–448 kbps (about 1.5–3.5 MB per minute). The conversion isn't adding bits, it's just storing every sample explicitly instead of using AC-3's perceptual compression. If size matters, convert to VOB to FLAC instead — same lossless quality, roughly half the bytes.

Will the audio quality improve by converting AC-3 to WAV?

No. The WAV decoded from an AC-3 track is bound by the AC-3 source: lossy compression artifacts that exist in the AC-3 stream will exist in the WAV. WAV is lossless going forward — anything you do to it after won't add compression loss — but it can't recover detail that AC-3's encoder discarded. WAV is about preserving what's there, not improving it.

What about the 4 GB WAV size limit — will my long DVD title break it?

A standard WAV file is capped at 4 GB by its 32-bit RIFF size header. At 48 kHz / 16-bit stereo PCM (~10 MB/min), you hit that ceiling around 6 hours and 40 minutes of audio. Trim long extracts with the Trim control (Step 3) and split into chapters, or use a lossless-compressed alternative like FLAC if you really need a single multi-hour file.

Can I extract just one audio track from a multi-language DVD?

In the current default flow, the first audio stream in the VOB is decoded. If your DVD has multiple language tracks (English, Spanish, director's commentary), the order they appear in the VOB depends on how the disc was authored — usually the primary language is first. For precise multi-track extraction (pick stream 2, 3, etc.), a desktop demuxer like PgcDemux gives you per-stream control before you upload.

Should I pick 44.1 kHz or 48 kHz as the output sample rate?

Use 48 kHz if the destination is video editing or you want to preserve the DVD's native rate (DVD-Video audio is almost always 48 kHz). Use 44.1 kHz if you're authoring an audio CD or matching iTunes/Spotify reference rates. Resampling 48 → 44.1 is well-defined and high-quality with modern algorithms, but skip it if you don't need it — every resample is a small computation, not a quality boost.

What's the difference between "Original" and "Stereo" for Audio Channel?

"Original" passes through whatever channel layout the VOB's audio carries — that might be mono (rare), stereo (most common), or 5.1 surround on premium DVD releases. "Stereo" forces a downmix to two channels, useful when you're sending the WAV into a tool that expects stereo input and would mishandle 5.1. "Mono" sums both channels and halves the file size; great for spoken-word content, wasteful for music.

Is there a file size limit?

We process files up to a generous server-side cap (multi-gigabyte uploads work for most users). For very large multi-VOB rips (a full DVD title can be 8 GB across segments), upload one VOB segment at a time or use the Trim VOB tool to slice out just the section you need before converting. Files process server-side then download as plain .wav — no account required, no watermark.
