High Definition Audio

Intel®
High Definition Audio
Integrated Audio for Today
and Tomorrow
Audio on the desktop PC has come a long way
from the warning beeps of the original PC. Most
systems today offer 44-kHz/16-bit stereo CD
quality, and many even add multiple channels to
provide a Dolby* Digital or DTS*-type surroundsound experience.
Integrated audio solutions such as AC’97 are costeffective and offer a good end-user experience in both stereo and multi-channel formats.
However, the current integrated audio capabilities fall short in meeting the requirements of the
next generation of PCs designed for digital entertainment.
Intel has worked with the industry to develop a new specification for integrated audio that is capable
of delivering the features and high-end performance of an add-in audio card. Intel®
High Definition
Audio (Intel®
HD Audio) is capable of playing back more channels at higher quality than previous
integrated audio formats. In addition, Intel®
HD Audio has the technology needed to support the latest and greatest audio content. By enabling enhanced usage models, Intel HD Audio, when combined with the Intel®
915G, 915P and 925X Express chipsets will also change how computer users
interact with sound.
The Challenge to Find Better Audio
When AC’97 was initially developed users were typically listening to only music and movies with
stereo sound. With the success of DVD movies encoded with Dolby Digital and DTS multi-channel
audio formats, users have become accustomed to listening in full surround sound with anywhere
from six to eight speakers.
While AC’97 technology has struggled to keep pace with all these advancements, Intel HD
Audio is designed specifically for the high-quality multi-channel audio experiences of today and
tomorrow. Newer audio and video encoding/decoding algorithms also enable a higher-quality
listening experience.
Sales BriefWith the explosion of digital content, more and more consumers
are moving their computers into the living room or family room
so they can enjoy digital music or movies throughout the house
on state-of-the-art multi-channel stereo systems or big screen
TVs. With better speakers connected to their computers, the
limitations of current computer sound subsystems, whether
integrated or add-in, can ruin the digital experience.
Many consumers are also starting to ask for the ability to play two
different audio streams through their PC at the same time—perhaps classical music in the study and a movie in the living room.
These demands cannot be met with current audio solutions.
An Outstanding Audio Experience
Intel HD Audio delivers significant improvements over previous
generation integrated audio and sound cards. Designed to
support the convergence of digital entertainment, the Intel HD
Audio specification delivers the features needed for an
improved audio experience.
Intel HD Audio is capable of delivering the support and sound
quality for up to eight channels at 192 kHz/32-bit quality, while
the AC’97 specification can only support six channels at
48 kHz/20-bit. In addition, Intel HD Audio is architected to
prevent the occasional glitches or pops that other audio
solutions can have by providing dedicated system bandwidth
for critical audio functions.
Innovative Uses for the Digital Home
Dolby Laboratories* selected Intel HD Audio to bring Dolbyquality surround sound technologies to the PC, as part of
their recently announced PC Logo Program. The combination of these technologies marks an important milestone in
delivering quality digital audio to consumers. Intel HD Audio
will be able to support all the Dolby technologies, including
the latest Dolby Pro Logic* IIx, which makes it possible to
enjoy older stereo content in 7.1 channel surround sound.
Another consumer need is for the ability to play back two
different audio tracks, such as a CD and a DVD simultaneously, which can’t be done using current audio solutions. Intel
HD Audio features multi-streaming capabilities that give users
the ability to send two or more different audio streams to
different places at the same time, from the same PC. Here
are examples of how this can be used:

CD
Dolby Digital
DTS
DVD Video

Chat Audio
Figure 1: You can play a game online and chat with the other players
by sending the game sound to 5.1 speakers while the Internet
chatting audio is sent through your headset.
Figure 2: A DVD movie with 5.1 audio can be sent to a surround sound system in the living room, while you listen to digital music and surf the
Web on the PC.Intel HD Audio handles these and other applications with ease,
which is attractive to users as multiple, simultaneous applications become more commonplace in the digital home.
Microsoft* has chosen Intel HD Audio as the main architecture for
their new Unified Audio Architecture* (UAA), which provides one
driver that will support all Intel HD Audio controllers and codecs.
While the Microsoft driver is expected to support basic Intel HD
Audio functions, codec vendors are expected to differentiate
their solutions by offering enhanced Intel HD audio solutions.
The result is high-quality PC based audio that delivers a
seamless convergence of digital entertainment between the
PC and consumer electronic devices.
Enhanced Features
Intel HD Audio also enables enhanced voice capture through
the use of array microphones, giving users more accurate
speech input. While other audio implementations have limited
support for simple array microphones, Intel HD Audio supports larger array microphones. By increasing the size of the
array microphone, users get incredibly clean input through
better noise cancellation and beam forming. This produces
higher-quality input to voice recognition, Voice over IP (VoIP),
and other voice-driven activities.
Intel HD Audio also provides improvements that support better
jack retasking. The computer can sense when a device is
plugged into an audio jack, determine what kind of device it is,
and change the port function if the device has been plugged
into the wrong port. For example, if a microphone is plugged
into a speaker jack, the computer will recognize the error and
can change the jack to function as a microphone jack. This is
an important step in getting audio to a point where it ‘just
works’—users won’t need to worry about getting the right
device plugged into the right audio jack.
The Solution for the Future
Intel HD Audio helps audio reach new levels with digital
quality audio and compelling new usage models for digital
home/office applications. Designed for “glitch-free” audio
playback, multi-streaming, jack retasking, and UAA support,
Intel HD Audio offers an audio solution for years to come.
As one of the many new technologies introduced with the
Intel®
925X and 915 Express chipset family, Intel HD Audio
enhances the end-user experience and enables the convergence of digital entertainment for both PCs and Consumer

Networking @ home

Networking @ home

Connecting multiple computers usually requires an Ethernet switch or a router. We show you how to network two PCs with a simple cross-cable in under Rs 100.

 

With laptops and netbooks becoming growingly affordable by the day, most homes would definitely have more than one computer. Data would also be scattered across these computers, be it music, videos or documents. In such a situation, transferring and synchronizing data between the computers is the need of the hour. This can be achieved with flash drives and external storage devices, but the transfer would be slower as it involves copying the data to the storage and then again to the other computer. Networking the two computers is the ideal solution, be it using Ethernet switches or routers, but the cost would be Rs 1,500 or higher, and it only makes sense if you need to network more than two computers. For connecting only two computers to each other, you can use a simple Ethernet cross-cable, which can be made in just Rs 100 or less. We show you how to network two computers in a simple two-section workshop.

 

Making the cross cable

Requirements: A minimum of two RJ45 connectors, CAT5 Ethernet cable (the length will depend on the distance required), and an RJ45 crimping tool.

Cut the required length of the CAT5 cable you need. Peel off the insulating sleeve at both ends by approximately 2.5 cm. Separate the four colored and white wire pairs from each other. Keep the blue and the orange pair and chop off the remaining two pairs as we need any two pairs for a cross-cable. Now straighten all the wires in a neat line and align them in the following manner — White Orange - Orange - White Blue - Blue. Next, neatly cut the edges of the wire in a manner that all the wires are now of the exact same length. Make sure the length of the wires coming out of the sleeves is around 1.5 cm. Now separate the last wire (Blue) from the others , keeping a gap of around ½ cm. The first three wires will connect to pin numbers 1, 2, and 3, and the last wire will connect to pin number 6 of the RJ45 connector. Now carefully insert the wires into the connector. Carefully match the colors with the pins and confirm they are in the exact order and groove. Push the wires all the way inside the connector using a little force. Finally, after ensuring that all wires are in place inside the connector, insert the connector into the crimping tool. Apply a little force on the cable to push the sleeve and the wires as far as they can go into the connector and immediately press the tool’s handle to crimp the connector. You should also hear a click sound when crimping to indicate the sleeve has been locked in position inside the connector. To crimp the other connector to the other end, follow the same procedure above, but the only difference now will be the order of the cable colors. This time, follow the order of the colors as follows — White Blue - Blue - White Orange - Orange. The rest of the procedure is the same. Your cable should now be ready for use.  Connect the cable to each computer’s Ethernet port and you are ready for the next step.

 

Networking the computers

In order to network two computers together, a few settings need to be altered in each computer’s network card properties section. Firstly, each computer has to have a unique name and a similar workgroup name. To change the names of the computer and workgroup, do the following - right-click on the ‘My Computer’ icon on the desktop and click on ‘Properties’. Select the ‘Computer Name’ tab (in Windows 7: ‘Advanced system settings | Computer Name’) and then click on the ‘Change’ button. Enter a different computer name for each computer and a similar workgroup name for both. Apply the changes and the system will prompt you to restart the computer. Choose to restart later. Now open the network section (For Windows XP: ‘Start | Settings | Network Connections’, and for Windows 7: ‘Start | Control Panel | Network and Internet | Network Connections’) and right-click on the Ethernet card, select ‘Properties’, and double-click on the ‘Internet Protocol TCP/IP’. Click on the radio button to enable ‘Use the following IP address’ and enter unique IP addresses along with the Subnet Mask in each computer’s network card. For example, enter the IP address ‘192.168.0.1’ on one PC and ‘192.168.0.2’ on the other while keeping the subnet mask common as ‘255.255.255.0’. Keep the DNS and Gateway fields blank. Apply the settings by clicking on ‘OK’ twice. Your computers are now networked. Now all you need is to share some folders or drives on each computer in order to exchange data.

 

This workshop can be carried further to share a single internet connection between the two computers by adding another Ethernet card on one computer and sharing the internet with the other.
