Features, Applications

is a high performance audio controller for the PCI Bus. DS-1E consists of two separated functional blocks. One is the PCI Audio block and the other is the Legacy Audio block. PCI Audio block provides 64-voice XG wavetable synthesizer with reverb and variation by using the software driver from YAMAHA. It also supports DirectSound hardware accelerator, Downloadable Sound (DLS) and DirectMusic accelerator. Legacy Audio block supports FM synthesizer, Sound Blaster Pro, MPU401 UART mode and Joystick function in order to provide hardware compatibility for numerous PC games on real DOS without any software driver. DS-1E supports the connection to AC'97 which provides high quality DAC, ADC and analog mixer, and it can connect two AC'97s. In addition, it supports consumer IEC958, Digital Audio Interface (SPDIF In/Out), to connect external audio equipment by digital. In addition to support the same functions (DS-1S), DS-1E adds direct recording function for SPDIF In, and realizes to use SPDIF In and Zoomed Video Port at the same time. And, DS-1E is featured with the capability of dramatically reducing power consumption at normal operation.

1. GM system level 1 GM system level is a world standard format about MIDI synthesizer which provides voice arrangements and MIDI functions. is a format about MIDI synthesizer that is proposed by YAMAHA, and keeps the upper compatibility of GM system level 1. 3. SONDIUS-XG Products bearing the SONDIUS-XG logo are licensed under patents of Stanford University and YAMAHA Corporation as listed on <>. The SONDIUS-XG produces acoustic sound Therefore, it provides outputs by running a virtual simulation of the actual acoustic instrument operation. that simply processes the recorded acoustic sound sources only. of virtual acoustic sound to the XG format. 4. Sensaura is a technology which provides 3D positional audio and moving effect by HRTF (Head Related Transfer Function) with 2 speakers or headphone. This feature makes it possible to enjoy invariable and unchangeable sound feelings in all-positional area covering as wide as 360 degrees. The good points are the voice arrangements kept extensively, a large number of the voices, modification of the voices, 3 kinds of effects, and so on.

much more real-world acoustic sound outputs fundamentally different from the Wavetable sound generator The SONDIUS-XG adds the technology
