HTPC Help Is On the Way, Go Troy Go!

If you've recently tried building an HTPC that can do all the basics, like play music, DVDs, plus play the latest HD formats like HD-DVD and Blu-Ray and have been frustrated with the incompatibilities between hardware, operating systems, drivers and A/V codecs, there might be some help in the very near future.

Troy, aka "pcCinema" on the AVS Forums, is offering to help everyone out. Troy started a thread titled, "Suppose I make it easy for all the newbies and budget folks?" back on August 16th to first announce his intentions and gauge interest. Troy is a former MCSE Senior IT Consultant who was responsible for the large scale automated rollout of PCs to corporate clients. He specializes in writing scripts or deployment tools that would make building high performance HTPCs easy for every newbie out there. He plans to maintain a website that would provide a list of high quality software and hardware components that have been fully tested for performance and compatibility with the required HTPC applications. Best bang-for-the-buck components would be included to make sure systems built from the recommended hardware list would also be affordable. Whenever, newer more advanced hardware or software is available and passes the necessary testing, the list will be updated.

After the user purchases his components based on the recommended hardware and software list, Troy's scripts would be used to assist with the process of assembling and installing all the hardware and software to create a trouble free HTPC. No more driver or codec conflicts. Finally, HD DVD and Blu-Ray playback will be stutter-free without all the hassles many people currently deal with today to get the correct combination of hardware and software to work together.

It's also interesting to note that Troy doesn't plan to charge a penny for any of his services. Troy doesn't sell any of the hardware or software, the user will have to shop for everything on his/her own. This is something he plans to do out of the goodness of his heart. Actually, it sounds very altruistic (it is), but he's also doing this out of self preservation. Troy explains that he is disabled and unemployed, waiting for Social Security benefits. He says he has nothing better to do with his time and since this is something he is very good at, he might as well do something he enjoys and allows him to be productive.

"It has been good for me to have a purpose again. I actually feel better physically and mentally now that I have this to focus on," Troy writes. "I've said it before that I've been going out of my mind with boredom, etc. I also want to make it good for the volunteers, and the community at large, and not just those that benefit from the plans directly. What's that they say about how people live longer if they have work to do? And the number one killer of retired people... "

Troy is hoping enough people will donate to his non-profit organization to help pay for the latest hardware and software that will be used to test for performance and compatibility with a high quality HTPC.

Interest in his proposal has been pretty positive. Of the 149 responses so far, it looks like more than 95% have been very encouraging. People are even willing to volunteer their time to help build a website (this one was thrown together pretty quickly by someone with the user name "pc1984" to demonstrate what he can do with a content management system (CMS) based website), help with the legal issues regarding setting up a non-profit organization, writing more advanced automation scripts, writing how-to guides and testing systems.

Well, I hope it works out. Personally, I'm pretty annoyed by all the hassles we have to deal with to get an HTPC to play all the high definition formats today. The latest dual/quad core CPUs from Intel or AMD and video cards from ATI or NVIDIA show promise, but sorting out the right combination of drivers, codecs and applications is enough to piss off an experienced HTPC builder. It will be interesting to see where this leads. I'll be paying close attention.

Good luck Troy!!

Networking problems when Vista Audio is Active

Just thought I'd relay some news about Vista audio that has been spreading around the last few days...

People have reported on the 2CPU forums that network performance is throttled whenever they play audio in Vista. It looks like more of an annoyance that a critical problem. Hopefully Microsoft will respond with a bug fix in the near future.

UPDATE 8/24: more information about this issues discussed in this AVS Forum thread.

HD-Audio - more comments

Constantin Gonzalez posted this excellent article: "So, where's the future of HD Audio?" in his blog a few days ago.

He explains that the music industry has 2 major problems with high definition audio:

1. most fans, retailers and music publishers don't care about HD audio
2. those that are interested in HD audio are a small niche scattered across many competing format choices

The first problem is due to the fact that most people have been told CD quality audio is good enough. Heck, most people are perfectly satisfied with less than CD quality - lossy encoded MP3s or AACs they either download from peer-to-peer sites or purchase from iTunes or other online music stores. Constantin explains that the human ear/brain is much more accurate and capable of hearing a higher dynamic range of audio and phase differences than is possible with CD recordings.

He's right. If only people knew what they were missing, maybe there would be more interest in HD audio. Some may argue that DVD quality video is also good enough, but the fact that more people are purchasing HD televisions, obviously they must believe there are added benefits to the higher resolution video images. Otherwise, why bother spending a few thousand dollars on a new screen when the standard definition screens are only a few hundred bucks and they work fine for watching DVDs. Now that they own a nice HD monitor, maybe they'll want to match it with a sound system capable of reproducing the audio tracks in all their higher resolution surround sound glory. If they appreciate the improved quality from the movie's sound tracks, maybe they will demand higher quality audio from the artists that provide rock, jazz, classical, etc., recordings.

Constantin says the second problem is really a mess and it is really about how the companies in the music business are competing to control the next popular format(s). The combination of competing media like SACD, DVD-Audio and now HD DVD and Blu-Ray, along with competing encoding methods like DSD or 24bit PCM with compression schemes from either Dolby, DTS, Meridian, etc., etc., AND the DRM methods employed to restrict copying resulting in a variety of hardware incompatibilities have just made the transition to HD audio very difficult.

All of this has created so much confusion with the average consumer that they are more inclined to just wait it out until a clear winner emerges so they don't mistakenly invest a lot of money in a bunch of discs or equipment that aren't supported in the future. Besides, the latest technology is always pretty expensive. Look at the historical prices of any consumer A/V products. Early VCRs were over $1,000, as were the earliest DVD players. Now look at how much they cost. Nobody wants to repeat the mistake of purchasing a $1,200 Beta VCR, like I did.

So, combining these problems we have the old chicken and the egg dilemma. Most people don't care about HD audio, but why should they? There's really not enough HD content out there to make it worth while on any single format. Maybe the big record labels are unwilling to produce albums on HD media until they are confident a secure HD format is popular enough to make it worth the necessary investment. Since most of the current HD audio content is offered through many small niches on either SACD or DVD-Audio and possibly HD DVD or Blu-Ray in the near future, there obviously is no clear winner. From a business perspective, compared to regular CDs and DVDs all of these higher quality formats are huge losers.

Oh, and to add to the confusion... Interactive MVI discs are the CD's newest rivals.

I guess this is one of the reasons why I think PC audio is the way to go. With a PC, you can play almost every media type and encoding method out there. You might not even have to deal with multiple media types if you choose to download from online music stores that offer HD audio albums.

I Got a Rocket in My Pocket

I found this great NRBQ clip on YouTube. I also got a kick out of some of the comments following the clip:

Huzzab: "Before I ever heard these guys, I read two reviews. One was "Good music to get drunk to." The other was "NRBQ doesn't let their exceptional musical ability get in the way of their playing". They certainly didn't let me down! Terry Adams is the devil incarnate."

seantgould: " best American rock and roll band EVER...u can't name any band with keyboard and guitar solos as cool as the Q...sorry, just my opinion"

chalkdavid: "Outstanding. Al and Terry solo their asses off and Joey and Tommy are about the most inventive rhythm section around."

What is HD Audio?

I just read a response by Mark Waldrup, Ph.D., to an article on HD Audio that appeared in SmartHouse News. Mark is the chief engineer at AIX Records. He's also the founder and director of the High Definition Surround Music Association (HDSMA), a non-profit dedicated to supplying accurate information and demos of HD Audio.

In his comments, Mark answers "What is HD Audio?"

Here's the definition the HDSMA prefers - "HD Audio is music or sound that is captured from the acoustic source at or near the fidelity of human hearing."

Mark explains that this means recorded/reproduced sound that has a frequency response of at least 20 kHz and a dynamic range of around 124 dB or more.

He goes on the say that the only consumer formats capable of supporting HD Audio fidelity are SACD and DVD-Audio. However, most of the SACD and DVD-Audio discs released are not true HD Audio because they are performances that were recorded before HD recording equipment was available. The analog tape equipment is only capable of a frequency response of 18 kHz and a signal to noise ratio of 72 dB, which is equivalent to a sample rate less than 44.1 kHz and a bit depth of 12 bits. Mark explains that even though you re-record it at 24 bit/96 kHz, it won't sound any better than the original analog master tape.

Mark also mentions that the HD in HD Radio doesn't stand for high definition, but is instead something like "hybrid digital." I agree that this is only adding to consumer confusion, especially when you consider that the resolution of HD Radio is only 64 kbps, which is half the bitrate of the worst quality MP3 or iTunes downloads available today.

Personally, I think the marketers have really screwed things up. It probably started when the marketing folks at Microsoft referred to the quality of their WMA encoder as "CD quality" when the bitrate was set to 128 kbps. The marketers probably know that if this kind of thing is repeated enough people will just accept it as fact (hmmm, that sounds familiar). Other companies simply play along. Now MusicGiants refers to their losslessly compressed tracks, which are really CD quality, as HD audio to distinguish it from the lossy encoded tracks available from the big music services like iTunes. Their 24 bit/96 kHz tracks are now referred to as "Super HD Audio". According to Mark, MusicGiant's "Super HD Audio" isn't even HD Audio because it was re-purposed from the original analog master tapes instead of recorded with actual HD equipment.

I have listened to 24 bit/96 kHz recordings (both 2 channel and 5.1 surround) from MusicGiants and they do sound better than the same recordings that I already owned on CD. However, I haven't had a chance to listen to the HD Audio offered by AIX Records. I first read about Mark (Dr. AIX) last Winter and am still waiting for them to launch their itrax.com website, which will offer HD Audio downloads. I thought their website was going to go live in June. I wonder what is holding them up... Anyhow, I am looking forward to hearing what Mark calls True HD audio. Hopefully they will have a diverse catalog with a lot of great artists to choose from.

What's taking so long?

Just a little update for those of you that might be wondering how our development is coming along...

We are still working on the 2nd generation prototype. There are a lot of updates to the original design. The amp modules are higher quality, the audio interface/soundcard section is going to be much improved and we hope to have a new power section. The main things holding us up are:

1. The audio interface/soundcard section still uses a FireWire (IEEE1394a) interface. Although, this still seems to be the best solution for multichannel sound, we are searching for a good multichannel USB2 solution. In either case (FireWire or USB2), we have a lot of work to do before completing the drivers and the control panel applet.
   
2. We are still waiting for a couple of key vendors to finish the development of their high quality (audiophile grade) switch-mode power supplies (SMPS). A SMPS will be a much more practical solution for a multichannel system. Linear supplies with adequate power will be very large and heavy and we'd like to design chassis' that weigh a lot less than 40 lbs and are smaller than a 1 drawer filing cabinet.

Flashback!

In my Enjoying My Tunes post from June 7th, I mentioned a Genesis concert that I went to in St. Louis when Peter Gabriel was the lead singer. My friend Rocky just sent me a link to this YouTube clip from another concert of Peter Gabriel and Genesis performing the same song: "I Know What I Like (In Your Wardrobe)", so I decided to post it to show what I meant when I said Peter Gabriel's performance was very theatrical.



Thanks for the flashback, Rocky!

2nd Generation Hybrid from LG Announced

This Engadget post (from 7/19, I know... old news, but I was on a short little vacation in northern Wisconsin and missed it) reports on another announcement from LG about their 2nd generation hybrid drives. The $500 GGW-H20LI reads both HD disc formats, and writes at 6x dual-layer BD-R/RE discs (as well as DVD±RW). There's also a cheaper drive that only reads the HD formats, but will write DVD±RW and CD-R/RW. Since the 1st gen drive was priced around $1K and now the 2nd gen is $500, I wonder how long it will take before these are offered for under $100. Maybe a year??
