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.

PAF (Paris Audio File) is the native audio format of the Ensoniq PARIS (Professional Audio Recording Integrated System) digital audio workstation, developed by Ensoniq in the late 1990s. PARIS was a hardware/software DAW that earned a loyal following among recording engineers for its warm analog-like sound and reliable operation, with PAF serving as its primary working file container. The format stores uncompressed PCM audio at 16-bit or 24-bit resolution and standard professional sample rates (44.1, 48, and 96 kHz), preserving full fidelity without lossy compression. PAF uses a straightforward binary layout — a compact header followed by interleaved sample data — enabling efficient real-time read and write during recording sessions. One notable advantage is support for both big-endian and little-endian byte ordering, reflecting the PARIS system's cross-platform roots on Mac and PC. After Ensoniq's acquisition by E-mu Systems and then Creative Technology, the PARIS DAW was discontinued, but PAF files remain important for studios with archived projects in this format. Tools like SoX and libsndfile can read and convert PAF files, ensuring long-term accessibility.

Frequently Asked Questions

Why convert CAVS to PAF?

Extracting audio from a CAVS video into PAF lets you keep just the soundtrack — ideal for listening without the video overhead.

Which applications support PAF?

Ensoniq audio tools, Audacity, and specialized converters support Paris Audio Format.

Can I choose the audio bitrate?

Yes. Adjust the bitrate, sample rate, and channel count before converting to get the PAF quality that suits your listening needs.

Is registration necessary?

No. Basic conversions work without an account. Signing up is optional and provides access to extended features and larger uploads.

Will the audio quality match the original?

You can set the output bitrate to match or exceed the original audio quality. Higher settings preserve more detail from the CAVS source.
