VOB to AIFF Converter

How to Convert VOB to AIFF 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. DVDs split content into 1 GiB chunks (VTS_01_1.VOB, VTS_01_2.VOB...) — upload them all and convert in batch.
2. Pick Audio Channel and Sample Rate: Leave Audio Channel on Original to keep the DVD's surround track as-is, or downmix to Stereo / Mono for podcast or archival use. Leave Audio Sample Rate on Original to preserve the DVD's native 48 kHz, or step down to 44.1 kHz to match CD masters and most DAW templates.
3. Trim (Optional): Use the Trim control to grab only the segment you need — enter start time and duration in HH:MM:SS.sss. Skip menu loops, commentary tracks, or commercials before they hit your AIFF.
4. Convert and Download: Click Convert. xconvert demuxes the MPEG program stream, decodes the AC-3 / MP2 / LPCM audio track, and writes uncompressed PCM 16-bit big-endian samples into an AIFF wrapper. No watermark, no sign-up.

Why Convert VOB to AIFF?

VOB is the container format used on DVD-Video — an MPEG program stream that multiplexes MPEG-2 video, audio (AC-3, MP2, or LPCM), subtitles, and menu data into chunks limited to 1 GiB per file. AIFF is Apple's 1988 lossless audio container; it stores uncompressed PCM, runs natively on macOS, and is the preferred ingest format for Logic Pro, GarageBand, Pro Tools, and Final Cut. Converting VOB to AIFF extracts the audio track at its highest possible fidelity for editing, archival, or post-production.

• Rip DVD soundtracks for editing — Pull dialogue, score, or sound effects off a DVD-Video disc into an AIFF that drops straight into Logic Pro X or Pro Tools without a transcode penalty on each playback.
• Archive home-movie audio from camcorder DVDs — Mini-DVD camcorders (Sony Handycam DCR-DVD series, Panasonic VDR series) wrote VOB files directly. AIFF preserves the original 48 kHz audio before the discs degrade.
• Extract concert or lecture audio for a podcast — Strip a 90-minute concert DVD into one AIFF, then trim, normalise, and re-encode to MP3 or AAC for distribution.
• Feed Apple ecosystem workflows — macOS, iTunes/Music, QuickTime, GarageBand, and Final Cut treat AIFF as a first-class citizen — no codec packs, no conversion warnings, no metadata stripping.
• Preserve uncompressed PCM for mastering — If the VOB carries an LPCM track (48 kHz / 16-bit), AIFF stores those exact samples without re-encoding. AC-3 sources are decoded once to PCM rather than re-decoded at each playback.
• Edit with non-Apple DAWs that still prefer AIFF — Audacity, Reaper, and Adobe Audition all open AIFF natively, making it a safer interchange format than format-locked DAW project files.

Frequently Asked Questions

Why is my AIFF roughly 5× larger than the VOB's audio track?

DVD AC-3 audio is lossy and compressed (typically 384–448 kbps for 5.1, ~192 kbps for stereo). AIFF stores uncompressed PCM at roughly 1,536 kbps for 48 kHz / 16-bit stereo. The decoder expands the AC-3 samples to raw PCM; no audio quality is added, but the byte count balloons. If you don't need uncompressed audio for editing, convert to MP3 or FLAC instead.

Will the conversion preserve 5.1 surround?

Yes if the source is AC-3 5.1 and you leave Audio Channel on Original — AIFF supports multichannel PCM. However, many editors expect stereo AIFF; downmixing to stereo at conversion time prevents channel-mapping headaches in DAWs that don't auto-handle 5.1 inputs.

Should I pick 44.1 kHz or 48 kHz?

48 kHz is the DVD-Video native rate, so it requires no resampling and is best if you're editing in a video-post timeline. Pick 44.1 kHz if the AIFF will land on a CD master, in a music DAW project already at 44.1 kHz, or in iTunes Match — resampling 48→44.1 kHz once at conversion is cleaner than resampling at every playback.

Can I convert just one chapter or scene from the DVD?

Yes. Either upload only the specific VTS_xx_x.VOB chunk you need, or upload the full set and use the Trim control to set start time + duration. Trim accepts HH:MM:SS.sss precision, so you can grab a single song from a concert disc to the millisecond.

My VOB has an LPCM audio track instead of AC-3. Will I get true lossless?

Yes. If the source VOB carries LPCM (48 kHz / 16-bit or 24-bit, common on music DVDs and some Hollywood "DVD-Audio" discs), the converter copies the PCM samples into the AIFF wrapper without re-encoding. The output is bit-identical to the source audio.

What's the difference between AIFF and AIFF-C (.aifc)?

AIFF stores raw uncompressed PCM. AIFF-C (also .aifc) is the same container but allows compressed audio inside — including Apple's sowt little-endian PCM variant that macOS writes by default. Both extensions open in Logic, GarageBand, and Pro Tools. If you specifically need the original 1988 big-endian AIFF, use this page; for the Apple-flavoured variant, see VOB to AIFC.

What if my VOB files are encrypted with CSS or AACS?

xconvert won't decrypt commercial DVD content protection — and rip­ping copy-protected discs may be illegal in your jurisdiction (DMCA in the US, EUCD in the EU). This tool is intended for home-movie DVDs (DCR-DVD camcorders, Panasonic VDR, wedding videographer masters), unencrypted content discs, or VOBs you've authored yourself with DVDStyler / iDVD.

Can I keep going to other formats after AIFF?

Yes. AIFF and WAV both carry uncompressed PCM, so AIFF to WAV is a metadata-level repack with no audio change. To compress further for distribution, AIFF to MP3 is the standard next step. If you want the full video instead of just audio, use VOB to MP4.

How long does a typical conversion take?

A 1 GiB VOB chunk with an AC-3 stereo track converts in roughly 30–60 seconds on a modern connection — the bottleneck is upload, not the demux/decode. A full DVD's worth of VTS_* files (4–8 GiB across multiple chunks) typically finishes in a few minutes if uploaded in batch.
