The heart of the Sound Blaster Live! Value is the EMU10K1 audio processor chip, which is the most powerful integrated music, audio and effects engine available. Every signal is processed at 32 bit,

48kHz using E-mu’s patented 8-point interpolation wave-table synthesis with much more powerful effects processing. Therefore, the result is a cleaner reproduction of the wave-table musical instruments at all degrees of pitch shifting.

Sound Blaster Live! Value lets users experience depth and realism beyond existing 3D audio. It even provides preset environments such as Hall, Cave or Underwater that can be supplied to your existing games and applications for incredibly true sound.

Sound Blaster Live! Value supports Surround Sound audio on the PC with built-in support for two or four speakers. With S/PDIF output now accommodated in this latest design, users would be able to experience the compelling 3D audio on superior multiple speaker systems such as Creative’s FPS2000 Digital or DeskTop Theater 5.1

DTT2500 Digital. Multi-speaker output also allows users to position any audio devices such as CD Audio, WAV or MIDI anywhere within the speaker environment. Sound Blaster Live! Value is now capable of producing a whopping 1024-voices. This remarkable

1024-voices capability goes beyond the quality and performance available in most professional music equipment. With additional voices, Sound Blaster Live! Value delivers richer MIDI playback, simultaneous playback of more instrument notes and multi-layering of instruments to create better quality sound.

With Environmental Audio Extension



(EAX), Creative has made it easier for any developer who wants to incorporate high-quality 3D audio environments into their titles. In addition, Sound Blaster PCI

Standard has provided Sound Blaster emulation on the PCI bus by using a combination of software and hardware wizardries.

Sound Blaster Live! Value is targeted at seamless integration into the

PC for the best novice and advanced users experience in gaming, professional music recording and playback, and DVD/Video playback.
