DSP Blaster 2.0 requires a genuine, 16-bit Creative Labs sound card because
it uses the officially undocumented but universally supported full-duplex
feature of these cards. RITTY 2.0 currently requires the same card for
PACTOR mode to meet PACTOR's stringent timing specs, but works in RTTY mode
with most sound cards, including 8-bit ones. The dynamic-range limitation
of 8-bit cards normally isn't a problem except during extremely strong
adjacent QRM. If you use your rig's CW IF filters you'll probably never
experience an 8-bit dynamic-range limitation.
