Medianix announces new demonstration board for virtual Dolby Surround Sound; The EVB25006-3 Board Enables Developers To Easily Implement 3D Audio For Video Games, PCs And Other Applications Using Only Two Speakers.MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--May 5, 1997--Medianix Semiconductor, Inc. today announced the availability of a new reference design and demonstration board for systems that deliver realistic three-dimensional (3D) sound from two ordinary stereo speakers. The EVB25006-3 board enables digital consumer audio developers to easily implement 3D surround sound An audio recording and playback system that uses five or more channels plus a subwoofer channel. See 5.1 channel and 3D audio. audio for such applications as video games See video game console. , PCs, and television and stereo systems using only two speakers. Based on the MED25006 Virtual Dolby(R) Surround processor IC (introduced by Medianix in January 1997), the demonstration board will be used as a reference design for original equipment manufacturers (OEMs) and by software developers to test and design new applications. With the addition of amplifier, speakers and audio source, the board provides a complete 3D surround sound audio system. It features plug-and play-operation and does not require a PC interface or any DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive programming for implementation. The board was designed to demonstrate the capability of the MED25006, which is an all-digital implementation of Virtual Dolby Surround A digital audio encoding system from Dolby that provides four channels. Derived from the Dolby Stereo technology used in movie theaters, Dolby Surround was introduced in the early 1980s for video soundtracks, audio cassettes, CDs, TV broadcasts, video games and PC software. using proprietary 24-bit DSP technology to digitally process two-channel audio into two-channel 3D surround sound. The IC includes digital Dolby ProLogic(TM) decoding de·code tr.v. de·cod·ed, de·cod·ing, de·codes 1. To convert from code into plain text. 2. To convert from a scrambled electronic signal into an interpretable one. 3. and Dolby's virtualizing algorithms on-chip. It is well suited for use throughout a product family (at a variety of price points) because it is capable of operating in full-digital Dolby Pro-Logic mode, Dolby 3 Stereo mode, and Virtual Dolby Surround mode. The demo board requires analog left and right audio inputs and provides analog left and right outputs, and is configured to operate in 2.0 channel Virtual Dolby surround mode. An on-board buffered coder/decoder (codec (1) (enCOder/DECoder) A hardware circuit that performs analog-to-digital conversion (ADC) and digital-to-analog (DAC) conversion. When analog signals are entered into a computer, cellphone or other device via a microphone or video source such as VHS tape or analog TV, ) provides 18-bit analog-to-digital and 18-bit digital-to-analog conversion digital-to-analog or D/A conversion, the process of changing discrete digital data into a continuously varying signal in relation to a standard or reference. of the audio signals, which simplifies interfacing with standard audio equipment. It operates with a +12 Vdc power supply. Sample quantities of the EVB25006-3 board are now available to software and game developers and OEMs. The board is priced at US $195.
