DVD VOBs contain AC3 (Dolby Digital), DTS, or LPCM audio designed for home theater systems. WMA (Windows Media Audio) is Microsoft's audio format, standard in the Windows ecosystem for music libraries, media servers, and legacy hardware. Converting VOB to WMA extracts DVD audio into Microsoft's native format.
Legacy Windows-based audio systems — Windows Media Center, Zune, older car stereos with WMA support, and enterprise media servers — require WMA format. Extracting DVD audio to WMA enables playback on these Microsoft-ecosystem devices.
WMA Pro offers quality comparable to AAC for surround sound from DVD sources, while WMA v2 provides the broadest legacy compatibility.
FFmpeg reads the VOB program stream, decodes AC3/DTS/LPCM audio, downmixes to stereo, and encodes to WMA using the wmav2 encoder. Output bitrates range from 64-320 kbps at sample rates up to 48 kHz. The ASF container with .wma extension wraps the audio. WMA Pro encoding is available for higher quality at lower bitrates.
WMA v2 at 192 kbps provides good quality from DVD AC3 sources — comparable to MP3 at similar bitrates. WMA Pro at 128 kbps approaches AAC quality. At 256 kbps, both WMA variants produce near-transparent audio from DVD sources.
