How to Get the Most Out of Your HDTV Audio

Maybe you just bought your first HDTV set and are very impressed with the quality of the picture but did you know you may be missing out on a big part of the experience by not adding a good sound system? Home theaters don’t necessarily mean expensive chairs, high-end projectors, and audiophile-caliber sound systems. These days, some extra speakers and a good audio video receiver (AVR) can add the missing dimension of realistic sounding audio. While you’re putting together your sound system here are six things to keep in mind.

1. You Can Start With a Subwoofer

Most HDTV sets do a great job with video but often compromise on audio components. Whether you're listening to a rock concert or an action film, deep resonant bass can make a dramatic difference, so at the very least, consider adding a subwoofer to boost the bass. If you're going to add a subwoofer you might as well go ahead and get the other 5 speakers to round out the 5.1 surround sound or add 2 more if you want to go all the way to 7.1.

2. Pay Attention to Speaker Placement

Aside from the quality of the speakers, where you place them in the room can make a big difference. Remember to move the speakers away from the wall and raise them off the floor. Moving the subwoofer to a different location can make a dramatic difference. Here’s a complete list of speaker placement tips including how to do the subwoofer crawl.

3. Don’t Box Your TV Speakers
into a Corner Placing the TV along with the speakers in the corner of a room can create undesirable reflections and make your audio sound worse. On the other hand, there are often advantages to placing smaller subwoofers in corners.

4. Don’t Buy the Wrong Speaker Set
Most quality speakers include a tweeter, a cone and a woofer in the same enclosure. Even though a small cube speaker might be easier to install, it's unlikely to produce the same quality sound as a larger speaker. Smaller speakers can often provide good quality sound for movies but for music or gaming you’re probably going to want an 8" or larger speaker. Remember that speakers have a subjective component and some listeners will prefer one set of speakers over another so try and listen to the speakers before you buy them. It’s okay to bring a CD or DVD of your favorite music or movie to try out on the sound systems.

5. Hook Up Everything Correctly
When hooking up speakers, avoid out of phase signals which can create unwanted effects by making sure the wire matches the red and black connectors on the TV or receiver and the speakers. Some receivers will compensate for out of phase signals while some others will provide a "phase warning" when using the automatic calibration microphone. HDMI is our preferred choice for connecting devices and the only way to get the highest quality audio from your Blu-ray player. It’s usually better to put your money into bigger speaker cables (more copper) than “expensive” cables. If you are hearing "Hum" or seeing "Snow" your cables probably need upgrading.

6. Overstuff Your Room

The acoustics of your room can make a significant difference in the quality of your audio system. Hardwood floors and bare walls can create unwanted reflections. You may want to consider installing an area rug on a bare floor, some wall coverings and of course, curtains on any windows. The more upholstered furniture like overstuffed chairs and sofas, the better. Bookshelves full of books are also good for room acoustics; just don't put speakers in them.

Window Phone - You Love it

When Microsoft unveiled Windows Phone 7 Series last month it greatly exceeded our wildest expectations, but it also raised one key question: what about the apps? Today Microsoft has addressed that at developer conference MIX10 with the unveiling of Windows Phone Marketplace for 7 Series and gave us a taste of some of the early apps.

So what did we learn? In a nutshell - despite the seemingly closed system of the new OS, apps will indeed be a key part. Like 7 Series they maintain the same panoramic swipe based layout as we saw from core OS services and this can be seen above with the first shots of the Associated Press news reader.

They will be built using both Microsoft Silverlight (that's one way to battle the Flash debate) with the XNA Framework for games and all developers will be given access to a handsets' accelerometer, GPS, hardware accelerated video, gesture controls and camera and microphone. Apps will also be available for trials, as well as free or purchase categories and in-app purchasing will feature.

Interestingly, Microsoft didn't really address the topic of multi-tasking, but did unveil a push notifications service similar to that on the iPhone. Whether this means there will be no multi-tasking (surely not, after all Windows Mobile has always been able to do this) is another question entirely, but it seems it will be much more closely regulated and kept to a minimum to preserve performance and battery life.

Early entries are promising with 3D shooter 'The Harvest' (shown in portrait) looking particularly impressive with destructible scenery and tying all progress and achievements directly to Xbox Live. Elsewhere Shazam showed off its ubiquitous music ID service and Seesmic demoed an early port of its Twitter client. Microsoft also announced its initial group of 7 Series partners including *deep breath*:

AWS Convergence Technologies ? WeatherBug, Citrix Systems Inc., Clarity Consulting Inc., Cypress Consulting, EA Mobile, Fandango Inc., Foursquare Labs Inc., frog design inc., Glu Mobile Inc., Graphic.ly, Hudson Entertainment Inc., IdentityMine Inc., IMDb.com Inc., Larva Labs, Match.com LLC, Matchbox Mobile Ltd., Microsoft Game Studios, Namco Networks America Inc., Oberon Media Inc., Pageonce Inc., Pandora Media Inc., Photobucket Inc., PopCap Games Inc., Seesmic, Shazam Entertainment Ltd., Sling Media, SPB Software Inc., stimulant, TeleCommunications Systems Inc., Touchality LLC and Vertigo Software Inc

That's a decent list and while we'd like to see some country specific partners (travel-based, for example) they are unlikely to be announced at this stage. Then again all developers keen to take a look at the platform can jump in now since Microsoft has made the first release candidate for Silverlight 4 available today along with Express Blend 4 Beta so coding work can begin.

All in all, we still have a lot of questions about Windows Phone 7 Series (not least some specifics on multi-tasking and why it has such a silly name), but with the OS not due until late Q3/early Q4 the basics are shaping up nicely...

Update: PCMag reports Microsoft has now confirmed multi-tasking won't be supported initially with windows Phone developer strategy head Charlie Kindel saying:

"Apps that run arbitrarily in the background create an end user experience where battery life and responsiveness of the system becomes … inconsistent. We focused on getting a set of experiences right where we didn't have to support [multitasking,] but we will over time."

Kindel also confirmed expandable storage will be forbidden on Windows Phone 7 Series handsets so there will be no microSD slots - unless they are locked into the phone. This will simplify things (a user knows exactly what they have available), but it seems a strange rule to enforce. I know Microsoft is keen to make the hardware experience on Windows Phone more consistent, but soon manufacturers will have virtually no way of distinguishing their handsets at all!
