About formats

AVI (Audio Video Interleave) is one of the oldest and most recognized multimedia container formats, introduced by Microsoft in November 1992 as part of its Video for Windows technology. Built on the Resource Interchange File Format (RIFF) structure, AVI interleaves audio and video data in alternating chunks, allowing synchronized playback without requiring sophisticated stream management. The format is codec-agnostic, meaning it can hold video compressed with virtually any codec, from early Cinepak and Indeo to modern DivX, Xvid, and H.264 streams. This flexibility contributed to widespread adoption across personal computers throughout the 1990s and 2000s. One notable characteristic is a straightforward internal structure that makes AVI files relatively easy to edit and process at the binary level compared to more complex modern containers. AVI also supports multiple audio streams, enabling multilingual content within a single file. However, the original specification has limitations, including a 2 GB file size ceiling in older implementations and no native support for variable frame rates or advanced subtitle formats. The OpenDML extensions (AVI 2.0) addressed the size limitation by allowing files to exceed the original boundary. Despite being decades old, AVI remains one of the most universally recognized multimedia formats and is still widely supported by media players and editing tools across all major operating systems.

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 AVI to WVE?

WVE is the audio format for Psion SIBO PDAs like the Series 3. Converting AVI audio to WVE lets you play sounds on these classic handhelds.

What devices play WVE files?

Psion Series 3, 3a, 3c, and other SIBO-based PDAs support WVE natively. Some retro computing emulators can also handle the format.

What encoding does WVE use?

WVE stores audio as 8-bit A-law encoded data. This provides reasonable voice quality while keeping file sizes manageable for older hardware.

Is WVE still in active use?

WVE is a legacy format tied to Psion PDAs from the 1990s. It remains relevant for retro computing enthusiasts and archival purposes.

Does the conversion keep voice clarity?

A-law encoding in WVE is optimized for speech. Voice content from AVI maintains good intelligibility on Psion hardware speakers.
