In recent years, we have experienced significant advances in the computer industry, especially in multimedia.
Multimedia and the Internet are the dominant trends in the two high-tech equipment, software and telecommunications. Both themes represent more than the Windows operating system, which includes very well-known multimedia features. Another big tendency is the explosion of household computers. Most computers on the market have at least a DVD-ROM unit.
In addition, the market for soundboards accepts further advanced audio performance, such as MIDI, which has grown spectacularly. With this technological development, it is no wonder that the Windows operating system includes many multimedia features. A few years ago, multimedia features were usually limited to closing windows, windows, programs, and more. Opening and some warnings and a kind of "music" – electronic music. Initially, the electronic music consisted of combined sounds that could reproduce some musical and some vague melodies, which was extraordinary because it was easier to use than an audio cassette. & # 39; 95, when Windows 95 was released, special software and hardware were created to convert music on an audio CD. The conversion was not complete, but the audio from the CD was transferred to the computer. More advanced systems and more efficient components have developed slowly. Today, music is mostly used in compressed MP3 format, but it focuses on different types of media. In the past, computers have generally provided users with poor quality media, text and graphics. However, better performance in the hardware components of the industry has led to a wider range of products that use CPU, graphics, sound, and full motion video intensively. To take advantage of multimedia components, you need to use additional hardware, more RAM (16-32 MB RAM), and probably a larger hard drive to store your used video and audio files. Today, music and sound on the computer have become vital. It must be continuous and multifaceted, but quality must be ensured. That's why some musical instruments with MIDI (Musical Instrument Interface) started to supply. MIDI is a protocol that enables the transfer of digital music between electronic devices, such as the PC and the keyboard. The required hardware, such as a PC card with MIDI playback options, will not have sound from MIDI data. So MIDI data only contains instructions that allow you to reproduce the desired music sound. One of the advantages of MIDI is the file size compared to the normal WAV file. WAV files have recorded all the sounds, so they can have huge dimensions. MIDI files only contain instructions for reproducing sounds and are therefore much smaller.
Because the number of multimedia and games, including MIDI, is increasing, the number of sound cards sold with such options (such as the MIDI standard port) is used to connect MIDI devices). In addition, MIDI, for example, can emphasize the impact of multimedia presentations, which seems realistic to emphasize on-screen visualization.
Even recording a good quality album is not an easy process. Computer processing is required. But the technician can't work without a good musician, and a musician can't work well without a technician.
Windows offers a number of options for using multimedia audio, including playing audio compact discs and customizing voice recording and playback. You can play an audio CD on a CD-ROM installed on your computer using the CD player. If there is a card, inserting the CD is enough to start the CD player: 1. Open the Start menu and select Accessories. 2. Select Multimedia, and then select the CD player. 3. Open CD playback.
Windows automatically detects compact CDs. When you start the CD, just click on the CD player. As the CD player runs in the background, you can listen to audio CDs while working on your computer.
From the sound of the old boards, which was limited to a beep from the small speaker on the motherboard, until the late 1980s, when sound cards started working, multimedia and computer games were at a completely different level. Today, these systems are more complex in terms of high professional standards. The motherboard and sound as well as the interface have more varied features. A computer motherboard, the main board, is the most important component of a computer house. In addition, the following components are used: microprocessor, memory and cards inserted into other special openings: sound, modem, network card, etc. In addition, parallel and serial ports installed can be used to connect peripheral devices such as mice. the printer, the modem.
Generally, sound cards are installed in the PCI slot, while older ones are usually installed on the ISA bus. Many computers now include sound chips directly on the motherboard. This leaves a gap open to other peripherals. Sound cards can be connected to
* Speakers with amplifier
* Analog input source for microphone, radio, box or CD player
* Source digital input as digital audio tape (DAT) or CD-ROM
* Analog Output Source – Cassette Cover
* Digital Output Source as DAT, CD Burn (CD-R)  Some sound cards provide a very efficient output for 4 speakers and a digital output interface. The sound comes with a new digital generation sound card. The sound card is practical for digital applications that require digital sound. Digital audio cards have digital audio inputs and digital outputs to transfer data directly from DAT, CD or DVD to your computer's hard drive. Generally, the sound card can make more sounds:
– to reproduce recorded music (CDs or audio files such as WAV or MP3), games or DVDs,
– Recording sounds from different external formats (external microphone or tape)
– synthesizing the sound.
The DAC (Digital Audio Controller) and ADC (Analog-to-Digital Converter) transmit and transmit sound to the sound card while the DSP (Digital Sound Processor) monitors the process. DSP also deals with any other sound reproduction, such as echo or 3D sound. As the DSP focuses on sound processing, the computer's processor can handle other things.
Sound cards using the old synthesizer to create the FM sounds. The synthesizer receives a variety of FM frequencies and combines them to create an approximation of a particular voice, such as a trumpet. While the FM synthesizer has evolved to a point that seems very realistic, it does not compare to the Wave Table synthesizer that records a small portion of the actual instrument's sound. This continues to sound like incredible precision. The Wave Table synthesizer has become the new standard for most sound cards, but some brands still use a cheaper FM synthesizer. Some sound cards contain both. Sound cards provide extremely sophisticated support for MIDI devices. With the music program, you can connect a MIDI-equipped instrument to your sound card, allowing you to see your music notes with your song.
Some people make so-called "musicians" music using computer programs that use sounds and rhythms as well as synthesizers. The music of these methods is quality music, even if it is real and clear. The tool itself prepares this. That's why classical music and live music are excellent because they are real musicians (professionals).
