About formats

VOB (Video Object) is the primary container format used on DVD-Video discs, defined as part of the DVD specification developed by the DVD Forum. The format first appeared with the DVD standard finalized in September 1996 and has since been used on billions of DVD discs produced worldwide. VOB files are based on the MPEG-2 program stream format, containing multiplexed MPEG-2 video alongside audio in AC-3 (Dolby Digital), DTS, MPEG-1 Layer II, or LPCM formats. Beyond audio and video, VOB files also carry DVD subtitle streams as bitmap overlays, navigation data for menu interaction, and chapter point information. The files reside in the VIDEO_TS directory on a DVD disc, with naming conventions (VTS_01_1.VOB, etc.) reflecting the title and part structure of the content. Individual VOB files are limited to approximately 1 GB to accommodate the UDF file system requirements, with longer content spanning multiple files seamlessly. The format supports both NTSC (720x480) and PAL (720x576) video resolutions at bit rates up to 9.8 Mbps for combined audio and video. Integration of video, multi-track audio, subtitles, and navigation into a single program stream made VOB a complete solution for consumer movie delivery. While streaming and newer disc formats have supplanted DVD for new content, VOB remains hugely relevant for accessing the vast library of existing DVD content.

WVE is the audio format native to the Psion Series 3 family of personal digital assistants, released by British company Psion PLC beginning in September 1991. These clamshell PDAs included a built-in voice recorder, and all dictation functionality relied on WVE files to store captured sound. Each file begins with the ASCII signature "ALawSoundFile**" followed by a minimal header, then raw A-law encoded audio sampled at 8 kHz — a rate inherited from digital telephony standards. At 8000 bytes per second, a one-minute recording occupies just 480 KB, which was essential given that Psion devices stored data on SRAM cards typically ranging from 128 KB to 2 MB. The A-law encoding provides reasonable speech clarity within these tight storage constraints, prioritizing intelligibility over high-fidelity reproduction. WVE files can be converted to WAV or other modern formats using SoX, Awave Studio, or specialized Psion file utilities. While the format is firmly a product of early-1990s handheld computing, it holds historical significance as one of the first audio recording formats designed for pocket-sized consumer devices. Collectors and researchers studying mobile computing history occasionally encounter WVE files when recovering data from legacy SRAM media.

Frequently Asked Questions

Why convert VOB to WVE?

WVE is the audio format for Psion SIBO PDAs. Converting VOB audio to WVE puts DVD sounds on vintage Psion pocket computers.

Which Psion devices play WVE?

Psion Series 3, 3a, 3c, and Siena play WVE natively. These 1990s handhelds use WVE as their standard audio format.

Does DVD surround audio convert?

WVE uses mono A-law encoding. DVD surround from VOB is mixed down to a single channel suitable for Psion speaker playback.

How does A-law handle DVD audio?

A-law is telephony-grade encoding. Speech content from DVDs sounds clear, but cinematic music loses significant detail in WVE.

Is WVE still used?

WVE is a legacy format for retro computing enthusiasts maintaining Psion SIBO hardware. It remains the standard audio format for these PDAs.
