  • Bijective BWT (7 Comments)

    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (113 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

  • Precomp: More Compression for your Compressed Files (3 Comments)

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

JVC Releases Digital Audio Player Featuring their K2 Technology

Posted by Sachin Garg on 19th September 2005 | Permanent Link

The XA-HD500 is equipped with JVC’s CC Converter to improve sound quality from compressed audio files using JVC’s unique K2 Technology for creating high-fidelity sound and featured in JVC’s Hi-Fi components. The CC Converter reclaims audio information lost during compression to WMA or MP3 format, enabling a more natural audio playback experience.

This is similar to what we reported about Creative’s new X-Fi series.

However, with users begging for more quality, cheaper/smaller storage is making lossless compression algorithms a more viable choice with every passing day. Such stuff can probably help cover the gap till they become mainstream.

Its strange why this device cares about quality but still doesnt supports any lossless audio format.

K2 Technology is a digital signal audio enhancing technology for eliminating non-signal noise that affects music signals, and is used in JVC recording studios and mastering studios. K2 Technology dramatically improves audio quality for everything from high quality linear PCM used in CD and DVD audio to compressed digital signals such as MPEG-2 AAC used in Dolby Digital, DTS and broadcast satellite and CS digital broadcasts.
