High Definition Multimedia Content Anyone?

Does the latest generation of downloadable high definition (HD) multimedia content worth viewing and hearing in our dedicated HD-ready home theater set-ups?


By: Vanessa Uy


Nowadays, HD (high definition) multimedia content (audio and video) that can be downloaded from the net via your own home PC is of such quality that most of them-if not all- deserve to be viewed and heard in your existing HD-ready home theater system. If you’re like me – as most of anyone in the audiophile community- who thinks that your PC and home theater system should not mix (i.e. share the same outlet) because the former can degrade the performance of the latter must face a somewhat insurmountable problem. How to send that high definition movie -with the attendant surround sound data- that you legally downloaded from the net, from your PC to your home theater set up?

There are a number of systems in which you can deliver/send that HD content you have downloaded from the web. One of them is a relatively new technology - which uses your mains/ac line to send your data. Consumer devices that utilize this principle of sending data only came to the market near the end of 1997. So the ones currently available in your local AV/computer store not only works better, it’s likely to be cheaper as well thanks to almost ten years of progress. This has the advantage of avoiding the clutter that can be created when installing the necessary data-transfer cables. The problem with this system is that if you own a state-of-the-art home theater system, you probably bought with it a very good dedicated mains/ac line filter to maintain the consistently good performance of your home theater system while protecting it from electrical interference and lightning strikes. The same mains/ac line conditioner blocks the digital data that you intend to send down your mains/ac lines. Another way to send your multimedia data while avoiding the clutter of additional cables is via WIFI or wireless data transfer systems. The current generation of WIFI systems can easily handle the bandwidth required in sending HD multimedia content but will be easily vulnerable to signal interference especially if you use your mobile phone while using the WIFI system. If you want to maintain signal integrity while transferring HD multimedia data, Ethernet networks are a good choice. A word of warning though because these systems involve additional wiring if you are squeamish about the clutter factor. The latest “Cat 6” or category 6 high speed Ethernet connections are a good choice and could be a very good investment because of it’s future proof status. This is due to the fact that it can handle data transfer speeds of 10 Gigabits per second and anything faster is yet in the far off future.

I just hope that the circa-2007 PC and AV convergence will bear the fruits of a better audio and video quality that doesn’t cost the earth. Unlike the divergence of 10 or 15 years ago were hi-fi manufacturers have the luxury of producing and selling obscenely expensive AV equipment with impunity. Since all of our present media formats are digital in one form or another, convergence is inevitable due to the fact that digital data is both robust and universal.

Will “We7” Save the Music Industry?

Will Peter Gabriel’s “We7” make music downloads equitable for musicians, music lovers and record label executives?


By: Vanessa Uy


Slated to be launched on June 2007, Peter Gabriel – supported “We7” not only promises to please musicians and record label executives but also provide a legal and legitimate music download service that’s free of charge for those who have acquired a taste of Napster’s “poisoned fruit.” The music downloads on “We7” are free in the sense that music lovers and/or fans don’t have to pay a single cent to the site. The site itself uses the revenue created by the adverts on the site itself to pay the musicians and record label executives according to how often their “works” are downloaded. Another “Bolshevist” feature of this site is that users are encouraged to share the music that they downloaded to other music lovers so that they will also “fall in love” with “We7”. To me this is a far better proposition than Digital Rights Management or DRM.

Sound quality issues aside, the downloadable music phenomena on the web has the advantage of worldwide accessibility that is quantum leaps ahead compared to traditional music distribution systems like record stores-even specialist ones. For example: the freak commercial success of Ed McMahon’s “Star Search” alumnus Tracey Spencer during 1989 has been a boon to music lovers everywhere who are into the politically-correct-side-of-altruism message. But a follow up of something similar has been slow in coming. The posthumous success of Nusrat Fateh Ali Khan to American MTV audiences in 1998 was much delayed due to the slowness of traditional music distribution systems back then. Even though a handful of adventurous music lovers has been enjoying the music of Nusrat Fateh Ali Khan in the US since the mid- 1980’s. If you seek to introduce a more adventurous variety to your musical taste, its much easier today via on- line music downloads. The Turkish-German R&B sensation Muhabbet became well known via the Internet. Muhabbet means to talk to each other in Turkish, has gained enough fame for his talent to be noticed. And now, Muhabbet has become UNICEF’s goodwill ambassador. Interested parties can contact Muhabbet at www.muhabbet.name.

I just hope that “We7” doesn’t forget the sound quality aspect of their site because as a legal music download site, sound quality can serve as a unique selling point for a site that supports the welfare of hardworking musicians and others in the music biz. As Peter Gabriel is a humanitarian-at-heart, the extent of “We7’s” benefits could put a major dent on extreme poverty. But for now, on line music download services like “We7” provides a level playing field for musicians anywhere in the world who are very talented but still lack the recognition they rightfully deserve.

The Computer and Hi-Fi Convergence

For as long as I can remember all of my audio buddies subscribe to the idea that computers are computers and hi-fis are hi-fis, and never the twain shall meet. Did recent technological progress and environmental issues conspiring to change even the staunchest audiophile's views?


By: Vanessa Uy


Back in May 2007, BBC’s Click featured a story on the computer industry’s efforts to improve the sound quality of their offerings. To me, this is a long time coming. Even if the computer industry only focus their R n D funds on surround sound, it’s still okay with me. The good news is that the computer industry reached a consensus that any form of data compression is detrimental to sound quality. To us audiophiles, this ranks with the world community’s consensus on the realities of global warming and climate change. From a telecommunications engineer’s standpoint, our current Internet infrastructure is presently the most efficient way to send digital multimedia data. It also has the potential to better itself in all aspects of quality as time goes on. Is the computer industry’s concept of high definition (HD) sound means just acceptable sound quality to us hardened audiophiles? Look at Sony’s SBM (super bit mapping) technology, we (the audiophile community) even wholeheartedly embraced it despite a failed promise in making CD sound as good as vinyl LP. All of this could kick- start a renaissance to most of the consumer electronic industry, but first let’s take a look back.

Back in September 1996, Audio magazines Corey Greenberg wrote a somewhat controversial article titled: “Shut the Hell Up Geeks” which was deemed offensive by the Personal Computer/internet enthusiasts at that time. For better or for worse, this article is only one of the few instances when the feud between audiophiles and computer enthusiasts got journalistic coverage. This feud, to me is even bigger than that between Bon Jovi and Metallica, which started in 1989 and reverberated throughout the Rock world till this day. I read Corey Greenberg’s article about three years ago, right about the time when I became interested in the audiophile universe. At this point in time, PCs came with CD “burners” as standard. And every time I copied/cloned a consumer grade original CD to CDR, the clone always sound inferior to the original. This only serves to prove that Corey Greenberg is right in pointing out the computer industry’s ignorance about the concept of sound quality. Note: I used Lunachicks CDs as a test case for copying. Their not locally released here. As Quentin Tarantino said back in2004 on the Tonight Show with Jay Leno: “It’s not piracy when you copy/clone music or movies of mine that is not locally released in your neck of the woods.”

In a few years since then, the computer industry has started to see the light – albeit slowly- on the merits of good sound quality. Creative, the company who brought PC audio recording to the masses with their “Soundblaster” has started a concept called Xfi or extreme fidelity. If this succeeds, the audiophile community can now buy the latest PC audio recording/playback systems in confidence knowing that ills like listening fatigue will be a thing of the past. Creative’s audio guru Darragh O’Toole, speaks out against the practice of data compression and its detrimental effects on digital audio sound quality. Data compression’s most obvious manifestation is the muted transients on recordings full of percussive sounds like cymbals and drums. I’m just glad that Creative: which is primarily a computer company supported Darragh O’Toole’s ideas instead of censuring. I wonder if Creative’s senior staff: are now composed of people who lived through the vinyl LP heyday and are nostalgic for the good sound quality for a consumer medium that it represents.

The 64,000dollar question is: “Why should we audiophiles – as a whole – give a damn?” If you live in a country like the Philippines, where the Estrada administration single-handedly bankrupted every specialist shops like mail order music stores with very good insurance coverage during the late 1990’s. Then the answer is a big resounding “yes.” Our local audiophile community is now feeling the guilt to that “preaching-to-the-choir movie” An Inconvenient Truth by Al Gore. To us its very over indulgent to hop to a plane to Hong Kong, just to buy locally unreleased albums/CDs by Lunachicks. Even though in the last three years I’ve planted about a thousand trees, I still choose to keep my carbon footprint as low as humanly possible. If this audio renaissance/convergence or whatever between the computer industry and the audiophile community is for real and not just a public relations stunt to patronize audiophiles and musicians. Then I may yet buy my first Internet downloaded album (I’m a Luddite-by-choice due to its present unacceptable sound quality). And in energy terms, this might only cost me a few watts from my photovoltaically charged batteries.
