An expansion board that enables a computer to manipulate and output sounds. Sound cards are necessary for nearly all CD-ROMs and have become commonplace on modern personal computers. Sound cards enable the computer to output sound through speakers connected to the board, to record sound input from a microphone connected to the computer, and manipulate sound stored on a disk.
Nearly all sound cards support MIDI, a standard for representing music electronically. In addition, most sound cards are Sound Blaster-compatible, which means that they can process commands written for a Sound Blaster card, the de facto standard for PC sound.
Sound cards use two basic methods to translate digital data into analog sounds:
FM Synthesis mimics different musical instruments according to built-in formulas.
Wavetable Synthesis relies on recordings of actual instruments to produce sound. Wavetable synthesis produces more accurate sound, but is also more expensive.
(1) A place from which data is taken. Many computer commands involve moving data. The place from which the data is moved is called the source, whereas the place it is moved to is called the destination or target. If you copy a file from one directory to another, for example, you copy it from […]
- Source Code
Program instructions in their original form. The word source differentiates code from various other forms that it can have (for example, object code and executable code). Initially, a programmer writes a program in a particular programming language. This form of the program is called the source program, or more generically, source code. To execute the […]
- source code control system
Abbreviated as SCCS, source code control system is tool used to track the development of a source file to prevent it from being altered by more than one person at a time. It is commonly used for projects where multiple source files are used or where multiple people are working with the source file. When […]
- source code manager
Abbreviated as SCM, source code manager is a set of tools used to manage the coding source for teamwork on Windows or UNIX platforms. SCM provides a permanent and secure data repository for source components.
- space shifting
The act of copying digital content for use on a device other than the one for which it is was originally intended, such as copying a music from a compact disc to an MP3 file for use on a portable MP3 player, or copying an MP3 file onto a compact disc for use in a […]
