In recent years, we have an important development in the computer industry see especially in the area of multimedia.
Multimedia and the Internet are two of the dominant trends in the field of high-tech equipment, software and telecommunications. Both subjects are represented more in the Windows operating system that includes well-known multimedia capabilities. Another important trend is the explosion of computers in the PC households. Most computers on the market now sells at least DVD-ROMUnit.
In addition to the sound board market, to accept additional enhanced audio performance, such as MIDI, which saw a spectacular growth. With this technology development, it is no wonder that Windows operating system contains many multimedia features. Close Up until a few years, multimedia functions usually contain only the noise of the window, open the windows, programs, etc. and a few warnings and a kind of "music" - electronic music. Was composed at the beginning of electronic musicSounds that could be reproduced in connection with some music and even had some vague melodies, the extraordinary, because it was easier to use than an audio-tape. After '95, when the operating system Windows 95 appeared, special hardware and software was created to convert music from cassettes to audio CDs. Conversion was not total, but a transfer from the audio CD on the PC. Slowly, things began to evolve, appear more advanced systems and more efficient components. Today, music is mostly used in compressedMP3 format, but it is positioned to different types of media. In the past, tended to offer computer users a series of poor quality media, text and graphics. But the improved performance of hardware components in the industry have a wide range of products, the degree to which the CPU, graphics functions, sound and full-motion video-guided use. To the benefits of multimedia components that you need additional hardware, more RAM (16-32 MB of RAM), and probably a bigger hard disk on whichto store video and audio files that you use. Today, music and sound on the computer has become essential. It should compress procedures and in many ways, but anyway the quality should be provided. That's why some instruments that are intended to start with the factory connector (MIDI) musical instruments interface. MIDI is a protocol that provides data transfer of digital music between electronic devices, enables, whether PC or keyboard. Without the necessary hardware such as PC Card with MIDIPlayback options, you have no sound from MIDI data. So MIDI data contain instructions that can only be played back the desired sound. One of the advantages it has, MIDI, WAV file to a normal file size is compared. Wav files included all the sound and can therefore have enormous dimensions. MIDI files only contain instructions for playing the sounds, and therefore are much smaller.
As the number of multimedia and games, including MIDI, a growing number of sound cardsthat with these opportunities (eg, a standard MIDI port for connecting MIDI instruments) are sold, also grows. Additionally, you can for example, MIDI, in order to emphasize the effect of multimedia presentations, realistic, visual presentation, which appears on the screen may seem to emphasize.
Another album of quality music recording is not a simple process. You need a DV editing. But the technician can not work without a good musician and a musician may not work well withoutTechnicians.
Windows provides several ways to use it to play multimedia audio, including the possibility of audio compact discs, and customizing the sound recording and playback. Installed play audio CD on a CD-ROM on your computer is possible, by using the CD player function. If you have a card, insert the CD into the drive is enough to launch the CD Player: 1 Open the Start menu and select accessories. 2. Select Multimedia and then select the CD player. 3. Access the CDPlay.
Windows can also detect automatically compressed audio discs, when in the CD-ROM set. Then, if you are the CD audio enough to click on the CD player. Since the CD player runs per background, you can listen to audio CDs while working on other applications on your PC.
From the sound of the old boards, the beeps were limited from a small speaker on the motherboard, in the late 80s, started working as sound cards, and multimedia and computer games through to an LEDComputer completely different level. Today, these systems are more complex when it comes to high professional standards. Motherboard and the sound and the interface there are different characteristics. Computer motherboard, the motherboard is the main component in the computer case. On it are the following components used: microprocessor, memory and other cards inserted into special slots: sound, modem, network card, etc.. Moreover, there are installed in parallel andused serial ports to connect peripherals such as mice, in conjunction with - printer, modem.
Most sound cards have installed into the PCI slot, while the older ones were usually on the ISA bus is installed. Many computer systems can now sound chips directly on the motherboard. This is a slot free for other peripherals leaves. Sound cards can be connected:
* Headset
* Speakers with Amplifier
* A source of the analog input as a microphone, a radio, aDeck with a box or a CD player
* A source of digital input as Digital Audio Tape (DAT) or CD-ROM
* A source for analog output - with Cassette Deck
* A source of digital output DAT burning a CD (CD-R)
Some sound cards have a socket in a very efficient output for 4 speakers and a digital output port. For audio, there is a new generation of digital sound card. A sound card is convenient for digital applicationsthat require digital sound. The digital sound cards, digital sound and digital outputs, so you can transfer data from DAT, CD or DVD to your hard drive into your computer. Normally, a sound card can do more things with clay:
- In order to reproduce music (from CDs or audio files like WAV or MP3), games or DVDs,
- The inclusion of audio in various media formats from various external sources (microphone or tape deckto)
- The synthesis of sound.
The DAC (Digital Audio Controller) and the ADC (analog-digital converter) to bring the transfer into and out of the sound card, while the DSP) (Digital Sound Processor to monitor the process. The DSP deals with any other sound change as an echo or 3D sound. As the emphasis on sound processing DSP, the processor of the computer with other things.
Sound cards used to create old synthesizer of the FM synthesis.Synthesizer takes notes of the various FM frequencies, and combines them to create an approximation of a certain sound, like a trumpet. While the FM synthesizer has reached a point that the very developing realistic sounds, it does not compare with Wave Table Synthesizer, which works by recording a small part of the actual instrument sound. This is still a solid play as well with incredible accuracy. Wave Table Synthesizer has become the new standard for most sound cards, but someBrands continue to use cheap FM synthesizers. Only a few sound cards, they are both. Sound cards have a much more sophisticated support for MIDI instruments. Equipped with a program of music, an instrument with MIDI are to be connected to the sound card, so you can see on the screen sheet music of your song.
Some people called "musicians' music produced with the help of computer programs that produce sounds and rhythms and with the help of synthesizers. The music is made these methodsQuality music, even if it sounds real and it is clear. It is made by the tool itself. Therefore, classical music and the live music is better because it has made by real musicians (professionals).
