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
TXW is the native audio sample format of the Yamaha TX16W, a rack-mounted digital sampler released by Yamaha in 1988. Each TXW file stores a single audio sample captured by the TX16W's 12-bit analog-to-digital converters, with selectable sampling rates of 16.7 kHz, 33.3 kHz, and 50 kHz in mono. The format was engineered to work within the sampler's architecture — 1.5 MB of onboard RAM expandable via memory cards — so files are compact and structured for quick loading from 3.5-inch floppy disks. Despite its 12-bit resolution, the TX16W earned a loyal following among electronic musicians who prized its distinctive warm, slightly gritty character that imparted a recognizable sonic texture to sampled material. The format preserves loop point data and tuning metadata, enabling seamless playback of sustain loops within the hardware. While TXW files are not directly playable in most modern software, conversion utilities and the SoX audio toolkit can transform them into contemporary formats like WAV or AIFF. For vintage synth enthusiasts and sample library curators, TXW remains an important archival format.

Frequently Asked Questions

Why convert CAVS to TXW?

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

How do I open a TXW file?

Yamaha synthesizer tools and sample editors support Yamaha TX Wave audio files.

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.

How fast is the audio extraction?

Audio extraction is quicker than full video conversion since only the sound track is processed. Most files are done within seconds.

Can I choose the audio bitrate?

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