About formats

CAVS (Chinese Audio Video Standard) is a video compression standard developed by the Audio Video Coding Standard Workgroup of China and adopted as a national standard (GB/T 20090.2) in February 2006. The project began in 2002 with the aim of creating an independent compression technology that could serve the massive broadcasting and multimedia infrastructure in China without relying on foreign-licensed codecs. CAVS, also referred to as AVS1, achieves compression efficiency comparable to H.264/AVC while utilizing a simpler patent framework with significantly lower licensing costs. The standard supports video resolutions from standard definition up to high definition, making it suitable for both terrestrial digital television broadcasting and broadband streaming. Key technical features include 8x8 block transforms, multiple prediction modes, and a loop filter designed to reduce blocking artifacts at low bit rates. The Chinese government endorsed CAVS as the mandatory compression standard for the national digital TV broadcasting system, ensuring broad deployment across set-top boxes and television receivers in the country. While CAVS has limited international adoption compared to H.264 or HEVC, its significance lies in serving one of the largest media markets in the world and demonstrating a viable national alternative to globally dominant video coding standards.
Initial release: February 2006
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.

Frequently Asked Questions

Why convert CAVS to FAP?

If you only need the audio from a CAVS recording, converting to FAP strips the video and produces a lightweight audio file.

What program opens FAP files?

Telephony systems and FAP-compatible audio processors handle FAP-encoded files.

Can I convert several files at once?

Yes. Upload multiple CAVS files and extract FAP audio from each one in a single batch operation — fast and convenient.

Do I need to install anything?

Not at all. The converter runs in your web browser — no downloads, plugins, or desktop applications are required for the conversion.

Does it work on phones and tablets?

Yes. The converter runs in any modern mobile browser on iOS and Android devices, with the same functionality as desktop.
