A technique for giving more depth to traditional stereo sound. Typically, 3-D sound, or 3-D audio, is produced by placing a device in a room with stereo speakers. The device dynamically analyzes the sound coming from the speakers and sends feedback to the sound system so that it can readjust the sound to give the impression that the speakers are further apart.
3-D audio devices are particularly popular for improving computer audio where the speakers tend to be small and close together. There are a number of 3-D audio devices that attach to a computer’s sound card.
- 3-D graphics
The field of computer graphics concerned with generating and displaying three-dimensional objects in a two-dimensional space (e.g., the display screen). Whereas pixels in a 2-dimensional graphic have the properties of position, color, and brightness, a 3-D pixels adds a depth property that indicates where the point lies on an imaginary Z-axis. When many 3-D pixels […]
- 3-D software
The category of software that represents 3-dimensional objects on a computer. This includes CAD/CAM, computer games, and animation packages.
3ivx is an MPEG-4 toolkit that supports MPEG-4 Video, MPEG-4 Audio and the MP4 file format. 3ivx allows video and audio to be compressed to a fraction of its original size while maintaining high image quality.
- 45 nanometer
45 nanometer (45 nm) is the buzzword of choice (2007-2008) for an advanced semiconductor manufacturing process that Intel used for mass chip production, starting in late 2007. The 45 nanometer manufacturing process uses new materials, including hafnium-based high-k gate dielectrics and metal gates, to reduce electrical current leakage in transistors. Contrast with 90 nanometer.
480p equates to 480 lines of progressive video (480 lines per frame). 480p60 refers to 60 frames per second; 480p30 refers to 30 frames per second; and 480p24 refers to 24 frames per second (film source). Usually refers to 720×480 (or 704×480) resolution.
