Portable players that have access to Internet or those that can store large number of digital music files are now very affordable, fun to use and designed just right to fit the modern generation’s lifestyle.

What is MP3?

MP3, an acronym for MPEG-1 Audio Layer 3, is one of the most popular digital audio encoding and compression formats being used nowadays and is apparently making an enormous impact on how people store, listen and share music of different genres. It is even now regarded as a standard technology used in greatly reducing the amount of data used to represent audio without altering the uncompressed audio’s sound quality when played.

Compressing Audio into MP3 Digital Music

The compression ratio of MP3 is 12:1, which means that a typical audio file that is 1200 KB big can be converted into a 100 KB MP3 digital music file without corrupting the sound quality of the original. In fact, some MP3 digital music are clearer and sound better since the compression process eliminates portions of the original music that are not too significant to human hearing. There are three ways through which the unwanted portions of the music are determined; among them is psychoacoustics, which is a study of how people subjectively perceive sounds.

MP3 digital music can be compressed with various bit rates (the number of bits of data representing a second of audio), which makes it possible for you to create different sizes and sound quality of an MP3 digital music converted from the same original digital audio file.

Usually, digital audio is compressed with bit rates ranging from 128 to 320. MP3 digital music encoded with low bitrate are of lower sound quality whereas those encoded with higher bitrate are clearer and more pleasing to the ears. However, there are also other factors affecting the quality of the compressed MP3 digital music; these are the quality of the encoder and complexity of the signal encoded. Moreover, the quality of the computer, the speaker or the earphones through which one listens to the music also affects his judgment with regard to the sound quality.

Benefits of MP3 Digital Music

MP3 digital music is very versatile. It can be played using your personal computer or a laptop; it can be played through a portable, small and light MP3 player; it can be decompressed and recorded on a compact disk; and can be easily downloaded via the Internet. Through several software, which are also available for free, you can easily create MP3 digital music from other digital audio formats.

The best things about MP3 digital music is that it is inexpensive and can even be obtained for free. It makes acquiring and listening to high quality music easier, more pleasurable, and particularly, cheaper. Its small size also allows you to store hundreds of MP3 digital music on your computer or MP3 player with ease, helping you save money you might have spent for CDs.

HDTV inherently provides a superior sound quality simply because the sound of HDTV is digitally transmitted. The difference in sound between an HDTV television and an analog television is rather noticeable. In fact, it is directly analogous to the difference between the music on CD’s compared to the music on audiocassette tapes.

The difference in sound quality provided by HDTV televisions and programming does not end there. Many HDTV programs are also broadcast in Dolby Digital 5.1 surround sound, but in order to take full advantage of this technology, it is necessary to have the right equipment.

Dolby technology has been created by Dolby Laboratories, Inc. This technology is the most renowned provider of digital audio technology. Also, Dolby Laboratories is known for reliable and superior products. For these reasons, Dolby Digital Surround has become the standard for HDTV. Many television manufacturers substitute their own surround sound systems, but they cannot live up to the reputation and performance of Dolby. Therefore, it important to check the specs on an HDTV television before buying in order to ensure that it uses Dolby Digital Surround.

When using Dolby Digital Surround Sound, there are three options for set up. The first option is to buy a television with high quality center channel speakers, woofers, tweeters, and Dolby technology installed in the television. With this option, it is unnecessary to buy addition equipment to take advantage of Dolby Digital Surround Sound.

Another option for taking advantage of the Dolby Digital Surround Sound with an HDTV is to connect an external set of surround speakers to the television. With this option, the surround sound set up includes a front pair of speakers, a surround pair of speakers, a center channel, and a subwoofer. Sometimes, the front speakers are “powered towers.” This means these towers include subwoofers.

The placement of these speakers is very important for the quality of the surround sound. The Center Channel Speaker should be centered either above or below the television. The Front Left and Right Speakers should be placed in an arc formation in line with the Center Channel Speaker. The Surround Left and Right Speakers, on the other hand, should be placed to the left and right sides behind the listening position. Many people choose to wall mount these speakers.

The third option for taking advantage of the Dolby Digital Surround System included in an HDTV television is to use an external set of front speakers can be connected to the HDTV television. This configuration is useful if there is not enough room to set up the external surround sound system and the HDTV does not come with Dolby Digital Surround installed. This isn’t true surround sound, but it is a viable alternative to those who can’t take advantage of the first two formats.

The audio and video outputs of the DVD or VCR can be connected to the AV receiver’s video outputs. If a separate DVD and VCR need to be connected, one can be connected to the VCR1 connection and the other can be connected to the VCR2 connection. The AV receiver’s VCR video and audio outputs should then be connected to the audio and video inputs of the DVD and/or VCR. In this way, the DVD and/or VCR will be able to record video signals that come through the AV receiver and the VHS tapes and/or DVD’s will be able to be viewed on the HDTV.

To take full advantage of the Dolby Digital Surround Sound technology, one of the video outputs of the DVD player and/or VCR needs to be connected to the AV receiver. The digital coaxial audio or digital optical connection must also be connected to the AV receiver.

How do I connect my CD player?

A CD player can be connected to an AV receiver. The CD player’s digital audio outputs can be used to connect the CD player to the AV receiver. A CD-Recorder can also be connected the AV receiver by using the Audio Tape Record/Playback input/output loop connections. In this way, the CD-Recorder will be able to function much like a standard audiocassette deck.

What else will I need?

Besides the basic electronic equipment needed to set up Dolby Digital Surround Sound, it is necessary to have connection cables. This includes video, audio, and loudspeaker connection cables. These cables need to be at an appropriate length in order to set the speakers in the proper position for optimal surround sound quality.
