DVD VOB files carry professional-grade audio — AC3 at up to 640 kbps, DTS at up to 1.5 Mbps, or LPCM at 1536 kbps uncompressed. AIFF (Audio Interchange File Format) is Apple's uncompressed PCM standard from 1988, native to Logic Pro, GarageBand, Pro Tools on macOS, and the entire Apple professional audio ecosystem. Converting VOB to AIFF extracts full-quality audio from DVDs for professional editing.
Professional audio editing on macOS demands uncompressed input. Extracting DVD audio to AIFF provides a lossless working copy for mixing, mastering, and post-production in Apple's professional tools. This is essential for film studies, music production from concert DVDs, and dialogue editing for dubbing or ADR.
AIFF preserves the full frequency response and dynamic range of the decoded DVD audio for iterative editing without accumulating compression artifacts.
FFmpeg reads the VOB program stream, decodes the audio track (AC3/DTS/LPCM) to raw PCM, and writes big-endian samples into the AIFF container. Default output is 16-bit/48 kHz (matching DVD's standard specification). 24-bit output is available for LPCM sources that carry it. Multi-channel content can be downmixed to stereo or preserved as multi-channel AIFF.
From LPCM DVD tracks, AIFF extraction is bit-perfect — identical to the disc master. From AC3/DTS, the AIFF captures the fully decoded audio at maximum fidelity. The quality ceiling is the DVD audio specification. No further degradation occurs during or after the extraction.
