Playback and Recording Sources
Digitized Sounds
Sound Blaster 16 Emulation in DOS box and real mode DOS.
Playback of 64 audio channels each at an arbituary sample rate.
Each audio channel can function as a WaveTable Synthesizer
voice.
Each audio channel can playback either 8 bit or 16 bit data from
host memory.
Pairs of audio channel can be programmed to play 8 or 16 bit
interleaved data from host memory.
48kHz recording from AC97 sample rate converted to 8 common
rates to host memory.
Playback Sources: CD_IN, CD_SPDIF, AUX_IN, LINE_IN,
MIC_IN, TAD, MIDI and Wave.
Recording Sources: CD_IN, CD_SPDIF, AUX_IN, LINE_IN,
MIC_IN, TAD, MIDI and Wave.
Full duplex recording and playback.
Wave Table Synthesis
E-mu
Systems EMU10K1

interpolation algorithm for excellent fidelity.
64 hardware and 1024 PCI wave-table synthesis
48 MIDI channels with 128 GM & GS-.compatible instruments and
10 drum kits
Uses SoundFont
technology for user-definable wave-table
sample sets; includes 2MB, 4MB and 8MB sets.
Loads up to 32MB of samples into host memory for professional
music reproduction.
Effects Engine
E-mu
Systems EMU10K1
Supports real-time digital effects like reverb, chorus, echo, flanger,
pitch shifting, vocal morpher, ring modulator, auto-wah or
distortion across any audio source.
Capable of processing, mixing and positioning audio streams
using up to 131 available hardware channels.
Customizable effects architecture allows audio effects and
channel control.
Full digital mixer maintains all sound mixing in the digital domain,
eliminating noise from the signal.
