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
FAP is a byte-swapped variant of the PAF (Paris Audio File) format associated with the Ensoniq PARIS digital audio workstation, a recording environment popular among project-studio engineers in the late 1990s. Where standard PAF stores sample data in big-endian order, FAP reverses the byte layout for little-endian architectures, enabling direct memory mapping on Intel-based processors without a runtime byte-swap penalty. The underlying payload is uncompressed linear PCM at up to 24-bit depth and 96 kHz sampling, preserving full studio-grade fidelity. Because there is no lossy coding stage, recordings survive unlimited edit cycles with zero generational loss — a critical property during tracking and mixing. The SoX command-line utility maintains read/write support for FAP, making it the most accessible tool for converting legacy PARIS sessions to modern formats. Despite its niche origins, FAP demonstrates solid engineering: the header is minimal and deterministic, eliminating ambiguity that sometimes plagues chunk-based containers. Advantages include bit-perfect audio preservation, fast I/O on x86 hardware due to native byte order, and straightforward interoperability with raw PCM tools.
