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
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.
