What you should know about multimedia

In recent years we have witnessed major developments in the target = "_self"> sector, especially in a multimedia computer.

Multimedia and Internet are two dominant trends in the field of equipment high technology, software and telecommunications. Both subjects are represented more in the Windows operating system, which contains well-known multimedia features. Another important trend is the explosion of computer PC at home. Most computers sold today at least one DVD-ROM.

In addition, the market for sound cards accepted new advanced audio performance, such as MIDI, which has grown dramatically. With This evolution of technology is not surprising that the Windows operating system includes many multimedia features. Until recently multimedia features include only the sounds of closing windows, opening windows, programs, etc and some caveats and a kind of "music" - electronic music. In electronic music was composed combination of sounds that could play music and even a few melodies wave, which was amazing because it was easier to use than an audio cassette. After '95 when the Windows operating system 95 appears, equipment and special software was created to convert music from audio CDs. Conversion is not total, but a transfer from the audio CD on your PC. Slowly, things began to evolve systems seem more advanced and efficient components. Today the music is used especially in compressed MP3 format, but addresses the various types of media. In the past, teams tend to offer consumers a range of media poor quality text and graphics. But the best performance of the hardware components of the industry leads to a wider range of products that use intensively the functions of the processor graphics, sound and full-motion video. To take advantage of elements multimedia you need additional hardware, more RAM (16-32 MB RAM) and probably a bigger hard drive to store the video and audio files you use. Today, music and sound on the computer has become vital. Must be processed and compressed in many respects, but quality should be taken anyway. Therefore, some musical instruments have begun to plant outlets (MIDI) interface instrument. MIDI is a protocol that allows data transfer digital music between electronic devices, a PC or a keyboard. Without the necessary equipment such as PC Card with MIDI playback options, no sound from MIDI data. If data MIDI only contain instructions that allow the desired sound that plays music. One of the advantages of MIDI, compared to a normal size of WAV files Archives. The WAV files recorded all the sounds and can be large. MIDI files only contain the instructions for the sound, and therefore are much more small.
As the number of multimedia and games, including MIDI, grows, the number of sound cards that are sold to these possibilities (for example, a standard MIDI port to connect MIDI instruments) becomes too much. Furthermore, for example, you can use MIDI to underscore the effect of multimedia presentations, may seem unrealistic emphasis on visual presentation, which appears on the screen.
However, to record an album of quality music is not an easy process. It is necessary for computer processing. But the coach can not function without a good musician and a musician can not well operate without a technician.

Windows provides several options for multimedia use audio, including the ability to play audio CDs and customize the registration sound and reading. Playing audio CDs on a CD-ROM is installed on your computer is possible with the function of CD. If you have a card, insert the CD into the drive Just run the CD: 1. Open the Start menu and select Accessories. 2. Select Multimedia and then select the CD. 3. Access CD playback.

Windows can also automatically recognize audio compact discs, when placed in the CD-ROM. Then, when you start the audio CD, just click on the CD. Since the CD player is running in the background, you can listen to audio CDs while working in other applications on your PC.

From the sound of old boards were limited to a small speaker beeps on the motherboard, to the late '80s, when the sound card began to work, multimedia and computer games aimed at a team level completely different. Now days, these systems are more complex when it comes to a high professional level. Mother and sound and the interface with different functions. computer motherboard, also known as Master Card, is the most important element in the computer case. It must implement the following: microprocessors, memory and other cards inserted into specific niches: the sound, modem, network cards, etc. In addition, parallel and serial ports installed for connecting peripherals such as mice - the printer, modem.

Stock charts her properly in the PCI slot, while the highest are generally installed on the ISA bus. Many computers now sound chips functionality directly into the motherboard. This leaves one free for other devices. Sound cards can be connected:

* Helmet
* Speakers with Amplifier
* A source of analog input from a microphone, a radio, a terrace with a box or CD
* An input source and digital audio tapes (DAT) or CD-ROM
* A source of the analog output - with cassette
* A source of digital production as a writing DAT (CD-R)

Some sound cards provide an outlet for large scale production effective for 4 speakers and a digital output interface. For audio, there is a new generation of digital sound cards. A sound card is useful for digital applications that require digital audio. sound cards have digital inputs and digital outputs digital audio, so you can transfer data from DAT, CD or DVD directly from the hard drive of your computer. Normally, a sound card can do more things with sound:

- To play recorded music (CDs or audio files to WAV or MP3), games or movies,

- To record audio in various media of various external sources (microphone or tape)

- Make sound synthesis.

The DAC (digital audio driver) and ADC (analog-digital) is the transmission input and output sound card, while the DSP (digital sound processor) monitor the process. The DSP also handles all further processing of sound as an echo or 3D sound. Because the center of audio processing DSP processor, the computer can deal with other matters.

sound cards use old synths to create sounds FM. FM synthesizer to vary the tones and combines them to create an approximation of a sound like a trumpet. Although the FM synthesizer has been developed to the point that sounds very realistic, does not compare with the synthesizer to table wave of artworks from registering a small portion of the real instrument. They continue to play a sound exactly like the fact with a precision incredible. Wave table synthesizer has become the new standard for sound cards, but some brands still use FM synthesizer at a lower cost. Few sound cards include both. The sound cards are supported very sophisticated as MIDI instruments. The use of a program of music, an instrument equipped MIDI can be connected to the sound card so you can see on the screen musical notes of your song.

Some people called "musicians" to produce music using computer programs that produce sounds and rhythms and with the help of synthesizers. The music made by these methods is quality music, even if it sounds real and clear. It is produced by the tool. Therefore, classical music and live music is superior because it is made by real musicians (professionals).
