Brand name of computers manufactured by Sony Consumer Electronics that includes both laptops and desktops. Supposedly is an acronym for "video audio input output" representing the core functionality of these multimedia convergence PCs. The "VA" in the VAIO logo resembles a sine wave alluding to analog signals and the "IO" alludes to digital on/off signals.
Sony offers many varieties of computers from ultra-lightweight portables to powerful desktops under their VAIO model line.
Super Audio Compact Disc. New media format developed by Sony and Philips that uses DSD (Direct Stream Digital) for audio rather than PCM (pulse-code modulation). Supports high-bitrate recording at 2.8 MHz and up to 5.1 channels of information. Greater dynamic range and frequency response than a regular CD. All SACDs required to have 2-channel DSD layer. Some are "hybrid" discs and have a PCM layer compatible with regular CD players.
Pink Floyd's "Dark Side of the Moon" was re-released in multichannel SACD format in 2003.
