About formats

WebM is an open, royalty-free multimedia container format developed by Google and launched at the Google I/O conference in May 2010. The format pairs the Matroska container (a subset of MKV) with VP8 or VP9 video codecs and Vorbis or Opus audio codecs, creating a fully open media stack designed specifically for web use. Google released WebM alongside the VP8 codec under permissive BSD-style licensing, removing patent and royalty barriers that hindered the adoption of H.264 for open web video. The WebM container inherits the efficient binary structure of Matroska while restricting it to web-optimized profiles, ensuring fast parsing and lightweight implementation in browsers. WebM with VP9 achieves compression efficiency competitive with H.264 High Profile and approaching HEVC, making it practical for delivering high-quality video at reduced bandwidth. Major web browsers including Chrome, Firefox, Edge, and Opera support WebM playback natively, and YouTube uses VP9 in WebM as a primary delivery format for much of its content. The format supports features such as alpha channel transparency in video, making it valuable for compositing web graphics and overlays. More recently, WebM has been extended to support AV1 video, continuing its evolution as a vehicle for open codec adoption. The combination of competitive compression, zero licensing costs, and universal browser support makes WebM a cornerstone of royalty-free web multimedia delivery.

PRC is an audio file format associated with Psion) handheld organizers, particularly the Series 3 and Series 5 lines from the 1990s. These pocket computers included built-in microphones and basic voice recording capabilities, storing captured audio in the PRC container. The encoding is typically ADPCM-based (Adaptive Differential Pulse-Code Modulation), balancing file size against audio intelligibility given the severe storage constraints of early PDAs — the original Psion Series 3 had just 256 KB of RAM doubling as storage. PRC audio is generally mono at low sample rates (often 8 kHz), optimized for speech rather than music. One advantage was tight integration with the EPOC operating system (later evolving into Symbian), letting users embed voice notes directly in agenda entries and database records. The compact file sizes — a minute of speech consumed only a few kilobytes — made it feasible to store dozens of memos on devices with minimal memory. While PRC audio is a legacy format today, conversion tools exist for extracting recordings from archived Psion devices, which remain collectible among retro computing enthusiasts.
