DVD VOB files contain high-quality audio tracks: AC3 (Dolby Digital) at up to 640 kbps, DTS at up to 1.5 Mbps, or LPCM at 1536 kbps uncompressed. FLAC (Free Lossless Audio Codec) is the universal open-source lossless audio standard, compressing PCM to 50-60% size with zero data loss. FLAC plays on Android, Windows, Linux, macOS, and virtually every audio device.
Extracting DVD audio to FLAC creates the most universally compatible lossless archive. Unlike Apple-centric ALAC, FLAC works across all platforms. FLAC from DVD LPCM sources is bit-perfect, and FLAC from AC3/DTS captures the fully decoded audio losslessly for future re-encoding to any format.
FLAC is the audiophile standard for lossless music libraries and the preferred format for extracting CD-quality or better audio from DVD sources.
FFmpeg reads the VOB program stream, selects the target audio track, decodes AC3/DTS/LPCM to raw PCM, and encodes using the FLAC encoder. Output at 16-bit/48 kHz matches the DVD standard specification. Compression levels 0-8 control encoding speed vs file size (level 5 default). FLAC supports Vorbis comment metadata for rich tagging. Multi-channel FLAC preserves 5.1 surround when needed.
FLAC is mathematically lossless. From DVD LPCM, the extraction is bit-perfect. From AC3/DTS, the FLAC captures every decoded sample without additional loss. The quality is the highest possible preservation of the DVD audio content.
