  • 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    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them.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.

    There aren’t too many companies working on cutting edge codecs, and of those few this one is hiring. Best of luck.

Creative Introduces Sound Blaster X-Fi

Posted by Sachin Garg on 10th August 2005 | Permanent Link

Creative’s new line of product comes with some sleak technologies.

“The CMSS-3D Headphone Expander technology will blow you away. You will think that you are listening to a super high quality surround speaker system, as the sound will seem to come from external speakers instead of headphones pressing right against your ears.”

“The Sound Blaster X-Fi XtremeMusic sound card harnesses the full power of the Creative X-Fi Xtreme Fidelity audio processor to upgrade any existing library of MP3 or any music files to the Xtreme Fidelity audio standard. With the X-Fi Xtreme Fidelity 24-bit Crystalizer, MP3 music and movies are converted to Xtreme Fidelity, which deliver an experience beyond the original CD or DVD recordings.”

“The Entertainment Mode accesses the X-Fi 24-bit Crystalizer, which is driven by the Creative X-Fi Xtreme Fidelity audio processor. The processor converts audio to 24-bit/96kHz quality using its 136dB virtually transparent SRC (Sample Rate Converter) engine. Then it re-masters and selectively enhances the audio by analyzing and identifying which parts of the audio stream have been restricted or damaged during the dynamic compression stages to 16-bit and then the data compression stage to MP3 or WMA formats. For music, low and high frequencies are enhanced while dynamics are improved, for cleaner, richer sound. For movies, explosions, gunshots and high-impact audio sequences sound more realistic than ever before.”

If lost information can be recreated, does this means that data compression algorithms can be more liberal with what is lost during compression, then artificially recreating the ‘quality’ during decompression?

    Once the information is gone, it’s gone. Just like “unsharp mask” might make a fuzzy photo look “better”, it doesn’t return it to the original. Audio post-processing like this is a marketing gimmick.

  2. Heliologue Says:

    Not only is it a marketing gimmick, but also a complete non-issue. We’re moving further and further away from lossy compression of any sort as our disk space and bandwidth expands. I think that our development of lossless compression, like jpeg2, flac/ape/&c and archiving formats will eventually displace any worries about data loss.

  3. Sachin Garg Says:

    Atleast with lossy compression, I feel perceived quality has always been the priority (not the information). It will ofcourse not be as good as original but if space is at premium, maybe encoders which specifically loose the kind of information which can be recreated can make a difference.

    Lossless is no doubt a better choice.

    Well I liked this article and found it very interesting. I have read some good reviews like the one over at Toms hardware http://www.tomshardware.com/consumer/20050818/ . I’m interested in the x-Fi Platinum and I have asked people to post them on a thread i started on the Creative X-Fi Forum http://www.productionforums.com/viewtopic.php?t=4598 . I would prefer to hear what owners say on the Platinum. I would also like to know other good speaker setups I could use for my x-fi
