About formats

AV1 (AOMedia Video 1) is an open, royalty-free video coding format developed by the Alliance for Open Media, a consortium whose founding members include Google, Mozilla, Microsoft, Amazon, Netflix, and Intel, among others. The specification was finalized in June 2018 with the goal of providing a next-generation video codec that surpasses the compression efficiency of H.264 and HEVC while remaining free from licensing fees. AV1 achieves roughly 30-50% better compression than HEVC at equivalent visual quality, making it particularly attractive for streaming platforms seeking to reduce bandwidth costs without sacrificing viewer experience. The codec supports a broad range of features including film grain synthesis, flexible tiling for parallel processing, content-adaptive resolution switching, and a rich set of intra and inter prediction modes. Hardware decoding support has expanded rapidly across mobile processors, GPUs, and smart TVs, addressing early concerns about computational demands during encoding. AV1 has seen wide adoption from major streaming services for delivering 4K and HDR content, and it serves as the video component of the WebM container for web-based playback. The royalty-free status makes AV1 especially important for open web standards and accessible media distribution.
Initial release: June 25, 2018
SNDT is the audio format associated with Sndtool, an early MS-DOS sound utility from the early 1990s that appeared alongside the spread of Sound Blaster cards in PCs. Unlike the headerless Sounder format, SNDT files include a brief header with the sample rate and data length — a meaningful improvement that let playback software determine timing automatically. Audio data is stored as 8-bit unsigned PCM, typically at 8000 to 22050 Hz in mono. Sndtool functioned as a simple waveform recorder and player, often distributed as shareware or bundled with sound card drivers. A key advantage over competing DOS audio formats was this self-describing header, which eliminated the guesswork of playing unfamiliar files — a real problem before standardized multimedia frameworks existed. The format was also efficient to decode, requiring no decompression and minimal CPU overhead on the 286 and 386 processors of the time. SNDT files served as building blocks for early PC games and multimedia presentations, where developers needed reliable audio across the limited Sound Blaster hardware ecosystem. Today, SNDT survives in retro software archives and is supported by SoX for conversion to modern formats.
