使用Aureal的Vortex2芯片的声卡已经开始问世了。我们拿到的第一块板载Vortex2芯片的声卡是DiamondMon-sterSoundMX300。Vortex2芯片支持Aureal的A3D2.0的3D立体声定位API和Direct-Sound3D。Aureal也在努力试图支持CreativeLabsEAX（环境音效扩展）,尽管完全的支持还没有与硬件紧密地结合起来。目前暂时EAX由主CPU来处理完成,不过Diamond准备将来发布一个新的驱动程序,从硬件上更好地支持EAX。由此可见MX300提供给了用户多种3D音效API,让用户自由选择,比较体贴用户。目前MX300不支持的3D音效API只有CRL的Sensaura,不过它没有广泛使用。MX300声卡本身较长,大约有全长尺寸的三分之二。在卡的背面有一个接口用来连接一块可选购的数字I/O子卡,在卡的正面也有一个接口用来连接一块硬件波表子卡。后一特性非常受欢迎,因为子卡将波表所需的内存减到最小。MIDI子卡的价格已经跌了不少,我见到YamahaSW50XG子卡最低卖到4O美元。我对这一特性也很满意,因为
Sound cards using Aureal’s Vortex2 chip are already available. The first sound card we got onboard the Vortex2 chip was the DiamondMon-sterSoundMX300. The Vortex2 chip supports Aureal’s A3D2.0 3D Stereo Positioning API and Direct-Sound3D. Aureal is also trying to support CreativeLabsEAX (Environmental Sound Extensions), though full support is not yet tightly integrated with the hardware. The current temporary EAX is handled by the main CPU, but Diamond is ready to release a new driver in the future to better support EAX in hardware. This shows the MX300 provides users with a variety of 3D audio API, allowing users the freedom to choose more considerate users. Currently MX300 does not support the 3D audio API only CRL Sensaura, but it is not widely used. MX300 sound card itself longer, about two-thirds of the full-size. There is an interface on the back of the card for connecting to an optional digital I / O daughter card. There is also an interface on the front of the card for connecting a hardware wavetable daughter card. The latter feature is very popular because the daughter card minimizes the memory required for the wavetable. MIDI daughter card prices have dropped a lot, I saw the lowest YamahaSW50XG daughter cards sold for 4O dollars. I am also very satisfied with this feature, because
