E-MU Digital Audio System
44.1 kHz. 48 kHz, 96 kHz derived from internal crystals
(no sample rate conversion is performed)
Externally supplied clock from S/PDIF.
(or word clock with optional Sync Card)
16-bit or 24-bit (depending on the setting of your recording or
audio application)
100MIPs custom audio DSP.
DSP - 32-bit integer math with a 67-bit accumulator
