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
GSM 06.10 (Full Rate) is the foundational speech codec of the Global System for Mobile Communications standard, ratified by ETSI in 1991 and deployed across hundreds of cellular networks worldwide. Operating at a fixed 13 kbit/s, the algorithm applies Regular Pulse Excitation with Long-Term Prediction (RPE-LTP) to compress 20 ms frames of 8 kHz mono speech into just 33 bytes each. This approach models the vocal tract as a linear predictive filter, encodes the excitation signal, and leverages pitch periodicity for further reduction — tuned to deliver intelligible voice under the bandwidth constraints of early digital mobile channels. The codec powers not only GSM telephony but also many VoIP applications, voicemail systems, and IVR platforms that benefit from its low bitrate. Three concrete advantages stand out. First, extraordinary compression: one minute of speech fits in roughly 100 KB, enabling efficient storage and transmission. Second, universal tooling — libraries such as libgsm and SoX handle encoding and decoding on every major platform. Third, a royalty-free patent landscape that has encouraged adoption across open-source telephony projects like Asterisk and FreeSWITCH.
Initial release: 1991
