About formats

AAF (Advanced Authoring Format) is a professional multimedia interchange format designed to facilitate the exchange of production data between content creation tools. Originally developed by a consortium including Microsoft, Avid Technology, and Adobe Systems, the format is now maintained by the Advanced Media Workflow Association (AMWA). First released in 1998, AAF provides a rich metadata framework that preserves not just audio and video essence data but also editorial decisions, effects parameters, transitions, and timeline structures. This makes it particularly valuable in post-production workflows where projects move between different editing systems and need to retain complex composition information that simpler formats would discard. AAF supports both embedded and referenced media, giving editors the flexibility to bundle everything into a single file or keep media external with linked references. The format handles multiple video and audio tracks with full timecode support, making it a reliable vehicle for broadcast and film projects. A structured approach to metadata preservation means that transitions, keyframes, and clip relationships survive the round-trip between applications, reducing rework and manual reconstruction when collaborating across different production platforms.
Initial release: April 3, 1998
DVMS (Dutch Voice Messaging System) is a telephony-grade audio encoding born from the Netherlands' early push toward digital voicemail infrastructure. Deployed through KPN (formerly PTT Telecom) in the mid-1980s, the format stores mono voice data at a narrow 8 kHz sample rate, prioritizing compact message size over sonic breadth. Audio is compressed with a proprietary variant of logarithmic companding similar to European A-law encoding, squeezing recordings to roughly 8 kbit/s while keeping speech intelligible. Each file carries a small header identifying sample rate, compression type, and message metadata, which made automated routing across early PBX and voicemail systems straightforward. Although DVMS never gained traction outside Dutch telecom circles, it influenced how European carriers designed later voice messaging protocols. Tools like SoX and several legacy telephony libraries still read and write DVMS files, allowing archival playback of decades-old messages. Among its practical advantages: extremely small file sizes (a one-minute message occupies roughly 60 KB), reliable speech clarity despite aggressive compression, and a simple container layout that is easy to parse programmatically.
