Introduction
Congratulations! You’re now a proud owner
of Sound Blaster
TM
Live!
TM
— the first in the
Environmental Audio TM family of audio cards
from Creative. Sound Blaster Live! is the
ultimate platform for the Environmental
Audio experience. At the heart of Sound
Blaster Live! is EMU10K1
TM
, a new
processor from E-mu Systems that is based on
E-mu’s highly acclaimed Emulator IV sound
module and Darwin hard disk recorder.
Leveraging over 25 years of expertise, the
EMU10K1 with more than 2 million
transistors and 1,000 MIPs of audio
processing power is capable of delivering
intensive digital mixing and effects
processing for a truly immersive
Environmental Audio experience. The
EMU10K1 is also endowed with these
powerful features:
❑
Advanced hardware-accelerated digital
effects processing
❑
32-bit digital processing, maintaining a
192 dB dynamic range
❑
Patented 8-point interpolation that
reduces noise/distortion to inaudible
levels
❑
64-voice hardware wavetable synthesizer
❑
Professional-quality digital mixing and
equalization
In addition to the high-performance
EMU10K1 audio processor, key technologies
in the form of several complex audio
processing and modeling algorithms are
implemented for Environmental Audio:
❑
E-mu Environmental Modeling
TM
E-mu has developed a method for
accurately positioning audio objects in a
3D space, calculating the necessary audio
reflections, and ultimately rendering the
3D environmental audio model. Through
extensive research, E-mu has produced a
real 3D experience by successfully
combining the best of multi-speaker and
psycho-acoustic 3D audio.
❑
DynaRAM
TM
Creative’s new patent-pending
DynaRAM technology makes the
downloading of sound samples more
robust by dynamically allocating host
memory for storing and processing the
samples—doing away with the need for
onboard audio card memory.
❑
SoundFont ®
SoundFont banks are software libraries of
sampled musical instrument sounds.
Unlike traditional wavetable synthesis
that made use of compressed sound
presets stored on the audio card’s limited
memory, SoundFonts can be easily
downloaded onto host memory as needed.
Less constrained by memory size,
SoundFonts can “capture” the full
expressiveness, tone and color of sounds
to deliver the realism expected of
Environmental Audio.
❑
Creative Multi Speaker Surround
TM
(CMSS
TM
)
CMSS, a novel multi-speaker technology
from Creative, allows Sound Blaster Live!
to support configurations of 4 to 8
speakers. With professional-quality
panning and mixing, independent
multiple sound sources can be moved and
placed seamlessly around a listener. When
combined with the E-mu Environmental
Modeling technology on the EMU10K1,
the user is presented with an audio
experience so real that it sounds Live!
