1.3.3 A better reproduction of analog filters
TAE allows the more precise emulation of analog filters over standard digital filters. To
obtain this result, the TAE technology is based on the analysis of the analog circuits to be
reproduced, and converts them in algorithms that faithfully mimic the characteristics of
the original filters. The curve underneath shows the comparison of the original CS-80
filter and that of the CS-80V.

1.3.4 Ring modulator
The CS-80V includes a ring modulator, just like the original CS-80. The ring modulator
allows the application of a waveform (a sinusoid) to another, in order to transform it. The
result is a more brilliant sound, distorted, and enriched in harmonics. As a result of this
increase in the number of harmonics, standard ring modulation algorithms create an
audible aliasing. To avoid this unwanted effect, TAE includes a module for the dynamic
control of the amplitude with aliasing correction, which removes every trace of aliasing in
the signal coming from the ring modulator.
