Introduce
CREATIVE ES1373 Sound Blaster AudioPCI
™
64V
The On-board audio controller is the new Creative AC97 digital controller which provides the
next generation of audio performance to the PC market. The ES1373 is available in a 5.0 V PCI
bus compatible device that enables the Creative/ENSONIQ Wavetable synthesis PCI solution.
The ES1373 chip includes a complete audio recording and playback system. The ES1373 inter-
faces to the PCI bus and to AC97, an industry standard CODEC/mixer. This solution is sound
Blaster PCI compatible utilizing a patented method of Sound Blaster emulation from Ensoniq. In
addition, it is compliant to AC97 interface, Microsoft PC97 and PC98, and Multimedia PC Level
II and III specifications.
The ES1373 provides 64 voices polyphony for wavetable audio, sound effects such as reverb,
chorus, bass, and treble. As a result, the produced music is more complete and closer to the
actual sound. What's more, the ES1373 supports the 3D Positional Audio algorithm from
Ensoniq. This 3D Positional Audio implementation also supports the Aureal A3D API for 3D
Positional Audio. This allows applications written to this API to run on the ES1373.
The ES1373 support Microsoft DirectSound, DirectSound 3D and DirectMusic. All of these
implementations are accelerated through the drivers from Ensoniq. This provides better overall
performance for the system and the audio quality.
