EAX ADVANCED HD™ Advanced Audio and 3D Audio Music Technologies


Optimized user-selectable settings for headphones, two, four or six speakers and external A/V amplifiers
Improved Creative Multi-Speaker Surround™ (CMSS) technology accurately places any mono or stereo source in a 360o audio space
Realistic EAX® technology reverb, panning and elevation effects bring life to your music and games
Advanced Time Scaling feature allows variable playback duration without altering pitch of original content
Powerful Audio Clean-Up feature removes noise and 'clicks' from playback of vinyl disks or cassette tape recordings
Dynamic Dolby Digital® Playback


Dolby Laboratory approved hardware. Dolby Digital decoding that does not rely on the host processor power for decoding, resulting in a consistent Dolby Digital playback that does not depend on the software or hardware DVD player
Dedicated Dolby Digital (AC-3) hardware DSP decoder with support of up to 24-bit I/O data format. Ability to decode Dolby Digital streams from optical, coaxial SPDIF input or host PC via USB connection
Built-in 24-bit DACs provide optimum audio resolution for Dolby Digital playback, making it the perfect partner for DVD applications
Optimum bass management feature allows speakers of different sizes to be accommodated - be it Creative Inspire™ range of 5.1 channel speakers or '6-channel ready' home A/V amplifiers
Provides mixing of Dolby Digital audio with the real-time gameplay audio effects - a feature that a normal consumer Dolby Digital A/V receiver is not capable of supporting Advanced USB Features
Optimized dynamic bandwidth allocation architecture for audio data transfer via USB bus. This architecture provides support of simultaneous playback of 5.1 multi-channel audio together with a compressed Dolby Digital (AC-3) stream. This is ideal for playing 3D games with Dolby Digital tracks
