ES1992

ESS Technology, Inc. DESCRIPTION The ES1992 Canyon3D™2 PCI audio accelerator combines advanced audio functionality in a highly integrated single-chip PCI solution for advanced multichannel PC audio. With key features including hardware acceleration, 3D audio support, digital output capability, and integrated quad DAC AC‘97 codec, the Canyon3D-2 will engulf the user in a 3D world of sound when used with general applications, digital music, or games. The ES1992 combines the advantages of a highbandwidth PCI bus interface, proven Canyon3D digital signal processing (DSP) hardware architecture, five-band speaker equalization (EQ), high-fidelity quad DAC AC‘97 codec into a single-chip package with an external AC-link for additional future functionality (i.e., 6-speaker, 5.1 channel output). A Sony/Philips digital interface (S/PDIF) output provides for digital output of multichannel AC-3 content. The result is robust PC audio functionality, which features digital mixing, sample rate conversion, realtime effects processing, multistream DirectSound® hardware acceleration, and head-related transfer function (HRTF) filtering. The 3D audio support and HRTF filtering are licensed through Sensaura™ Ltd. HRTF filtering is supported for 2, 4, and 6 speaker outputs, using MultiDrive™ technology. 3D audio is supported through DirectSound 3D, A3D 1.0, EAX 1.0, EAX 2.0, and I3DL2 advanced programming interfaces (APIs). Additional 3D audio enhancements are available through MacroFX™, Environmenta...
