Custom Audio Control Essay

Audio control is an essential part of the existing ways of interaction and it is possible to provide a thorough analysis of it through the connection to the term multimedia. This idea was suggested during a literature research because the greater part of the scientific literature in this field of study covers the aspect of sound and audio through the concept of multimedia. Nowadays, the term multimedia is widely used in computing.

The new expressions like multimedia audio controller, multimedia application or multimedia computer emerged in the sphere of computer science. In the course of time audio controller systems underwent the changes that caused an intense development of this section of computer related technology. A lot of researchers provided a documented and deeply investigated study of this type of control systems. Audio is an essential part of the latest computer technologies.

Audio systems produce a great effect that accompanies the video flow of interaction. Thus, these two factors determine the term multimedia (Zettl, 204). That is why in a more generalized sense it makes one of the possible ways of interaction that is managed by the audio and video effects. This includes images like photos and video, sound, text, and supports interactive control of their interaction. As applied to computer science term has acquired a narrower meaning about 10-15 years ago (Ronan, 64). According to the above mentioned definition, almost any computer game is a multimedia. Even those games with no audio output for multimedia audio controller, and on-speaker beeper belong to this concept. But a few can call it multimedia.

Computers have become multi-media only with the advent of convenient storage media, the first of which were compact discs, and output devices, high-quality sound produced due to the audio controller.

If the audio controller does not work properly, it substantially reduces the possibility of using the computer as a multimedia solution. For the greater part of modern applications, it is as important as the video card. Audio controller is sometimes called a sound card, because it is responsible for the sound output. It exists in three versions: the expansion card that is inserted into an available PCI or PCI-Express slot, AC97 Codec chip or HD Audio, placed on the motherboard, and the external device connected to the USB connector..

The work of the greater part of these components of computer is possible because of the appropriate drivers. Audio controller is no exception. Driver is a small control program, through which an operating system that includes any application, can interact with the device. Drivers are set once and registered in the system. If an audio controller driver is not installed, the sound output is not possible, although physically the chip of the device can be fully operational.

Although most computer systems can produce sounds without installing of special drivers, this is easily explained by the fact that many operating systems, including Linux, already have drivers for most popular devices, so when the process of system installation of base takes place, it automatically and invisibly to the user installs all components to the computer. The need to select independently and install drivers occurs in two cases: if the basic operating system has no corresponding program. This is possible when too new hardware unknown to a computer operating system is connected to it. It is not difficult to find out that in the distribution of Windows drivers include only those existed at the time of creating the product on the market.

Moreover, support for many specific components is also available (Huntington, 34). A driver disk always accompanies all new licensed devices.

There is an option of updating a driver of a device in the system. Audio adapter periodically releases updated versions of the software for the devices. Upgrading often improves the component of the computer by giving it new features and capabilities. The update can be downloaded directly from the device manufacturer. The greater part of the research that took place in the sphere of investigation the audio control focus on the possibility to engage the better reaction of the input signal and apply it to the program and the audio flow.

The effect is intensified by the special set of function commands performed by an audio controller. The results of the research present an image of the existing functions and work principles of audio controls. There are also kind of specific audio controls that function as connectors of the music or any other audio flow with LED systems and make a base for the effect of color that accompanies the music. The findings represent the next most common facts and principles of work as LED bulbs and ribbons connected to audio equipment and allow the LED lights to move in various modes according to the beat of the music played. The controller for LED stripe works by signaling from the music center and forward them to the LED device.

Some models of these devices do not require a direct connection to audio equipment. The audio can be equipped with a microphone or a connector for microphones, which captures sound waves and emits light signals according to the rhythmic patterns of music. There are many different modes for light moving modes like pulsation, rapid and smooth transitions from color to color in time with the audio signals and other options of the controller. This is usually provided with the help of the remote control.

Another kind of audio control system is a home theater audio controller scheme, which is based on a multi-channel and multi-channel audio processor PT2322 and PT2323 audio controller of Taiwanese PTC production.

These audio controllers are treated with 6 audio channels that implement sound format to 5.1 that includes a pair of front channels, a pair of rear speakers, center channel and subwoofer channel.

The most characteristic features of audio control include such options and features like the possibility of adjusting them to a computer operating system and optimization of their work with the help of the drivers. There is a possibility to combine LED systems to audio controllers that create an effect of light modifications accompanied by the surrounding audio flow. The given research is different for presenting the totally different spheres of applying the audio control systems in the technical devices. This can suggest some further investigations in the sphere of applying audio control systems to other spheres of the technical side of life. Sound is an essential part of human life and audio control systems serve as the convenient connectors of human interaction with audio equipment.
