Thunder Board
The Thunder Board was an 8-bit mono personal computer integrated circuit sound card from Media Vision, that had Sound Blaster compatibility at a reduced price. It was widely advertised as “proudly made in the USA”; possibly a reference to the Sound Blaster, manufactured by the competing Singapore-based Creative Technologies.

Sound Card
A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term ''sound card'' is also applied to external audio interfaces used for professional audio applications. Sound functionality can also be integrated onto the motherboard, using components similar to those found on plug-in cards. The integrated sound system is often still referred to as a ''sound card''. Sound processing hardware is also present on modern video cards with HDMI to output sound along with the video using that connector; previously they used a S/PDIF connection to the motherboard or sound card. Typical uses of sound cards or sound card functionality include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection. Sound cards are also used for computer-base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media Vision
Media Vision Technology, Inc., was an American electronics manufacturer of primarily computer sound cards and CD-ROM kits, operating from 1990 to approximately 1995 in Fremont, California. Media Vision was widely known for its Pro AudioSpectrum PC sound cards—which it often bundled with CD-ROM drives—it is also known for its spectacular growth and demise. Company history Media Vision was founded in May 1990 by Paul Jain and Tim Bratton. Early employees also included Russ Faust, Michael Humphries, Dan Gochnauer, Bryan Colvin and Doug Cody, all from Jain's prior company, Video-7. As Bratton recalls, he wrote the company's business plan while an engineer at National Semiconductor based on Jain's vision of evolving multimedia from VGA to audio and video. Jain raised funding, based on a business plan on a single sheet of paper, from top VCs such as Brentwood, Nazem, 3i and others. Media Vision became a publicly traded company in late 1992. In 1993, Media Vision took over Pelluci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Blaster
Sound Blaster is a family of sound cards designed by Singaporean technology company Creative Technology (known in the US as Creative Labs). Sound Blaster sound cards were the de facto standard for consumer audio on the IBM PC compatible system platform, until the widespread transition to ''Microsoft'' Windows 95, which standardized the programming interface at application level (eliminating the importance of backward compatibility with Sound Blaster), and the evolution in PC design led to onboard audio electronics, which commoditized PC audio functionality. By 1995, Sound Blaster cards had sold over 15 million units worldwide and accounted for seven out of ten sound card sales. Creative Music System and Game Blaster Creative Music System The history of Creative sound cards started with the release of the Creative Music System ("C/MS") CT-1300 board in August 1987. It contained two Philips SAA1099 integrated circuits, which, together, provided 12 channels of square-wave "bee-i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha YM3812
The OPL (FM Operator Type-L) series are a family of Sound chip, sound chips developed by Yamaha Corporation, Yamaha. The OPL series are low-cost sound chips providing frequency modulation synthesis, FM synthesis for use in computing, music and video game applications. Internal operation The internal operation of the chips is completely digital. Each FM-tone is generated by a digital oscillator using a form of direct digital synthesis. A low-frequency oscillator and an envelope generator drive an FM operator to produce floating-point output for the DAC. Decapsulation of the chips shows two look-up tables, one for calculating exponents and one for log-sine. This allows the FM operator to calculate its output without any multipliers, using the formula \exp [\log \sin[\varphi_2 + \exp [\log \sin [\varphi_1] + A_1 + A_2] and two 256-entry look-up tables. Both tables are stored as pairs of values rounded to the nearest whole number, with the second value represented as the difference b ...
