Oversampling 2

 (Impulse optimised filter) 

 
Shortening  the  filter  (lower  coefficient)  reduces  the  time  range  errors,  albeit 
combined  with  a  slight  loss  of  linearity  in  the  frequency  range  and  damping 
performance.

Oversampling 3 (Bezier-interpolator plus IIR-filter) 
 

In this process an ideal Bezier interpolator is combined with what is known as an 
IIR  filter.  This  eliminates  the  problematic  pre-echo  of  the  FIR  method.  This 
process  produces  highly  „analogueue“  system  characteristics,  with  a  sound 
quality and measured performance similar to those of good analogueue record 
players.

Oversampling 4

 (pure 

Bezier

 interpolator) 

 
This  process  delivers  a  perfect  reconstruction  of  the  original  music  signal.  It 
exhibits  no  pre-  or  post-echoes  of  any  kind,  and  does  not  add  coloration  or 
timing  errors  to  the  original  signal.  In  sonic  terms  this  method  offers  an 
impressive blend of naturalness, good dynamics and accuracy.
