1.4.8 Audio-Rate Modulation

The new engine can be set to audio-rate modulation
mode, allowing all synthesizer parameters (except the
master effects) to be modulated at audio-rate. Audio-
rate modulation is very CPU-intensive, but allows to
develop new sounds with rapid modulations previously
not possible.

1.4.9 Multi-threaded processing

Most DSP algorithms employed in Dune 2 are a magni-
tude more complex than previously, in order to achieve
a yet higher sound quality. This also means a much
higher computational load, at least in theory. In prac-
tice the optimized SSE vector code, as well as the
multi-threaded engine lower the processor load sub-
stantially. On modern, optimized quad-core or better
systems, Dune 2 can even outperform Dune 1 in some
cases.
