Upsampling Options

The optional 

Filters

 give different trade-offs between impulse response and 

aliasing. The table below shows how many filter choices are available for 
each combination.

OUTPUT RATE

INPU

T RATE

 
For most conversions, only 

Filter 1

 is available - a classic sharp filter. The 

amplitude is reduced by 0.1dB to match the other filters. 
 
For conversions with 2 filters (currently all of these have a 44.1k input rate):  

Filter 1

 is a classic sharp filter. The 44.1k

→

44.1k conversion has no filtering, 

the level is reduced by 0.1dB. 

Filter 2

 is a very steep, long apodising filter which starts rolling off at 20kHz 

(19kHz for the 44.1k

→

44.1k conversion). This filter is asymmetric – there is 

no energy left in the output to exercise the DAC’s filter, so there is no pre-
ringing from the source and the DAC. This will improve the response of the 
DAC’s reconstruction filter by removing some high frequency components 
that typically cause images in half-band filter DACs. 
 
For conversions with 4 filters: 

Filter 1

 has the sharpest cut-off, and so has the poorest impulse response 

(transient performance) but the best alias rejection (removal of out-of-band 
frequencies). 

Filters 2

, 

3

 and 

4

 have progressively gentler cut-off, with less alias rejection.  

 
For conversions with 5 filters (currently all of these have a 44.1k input rate): 

Filters 1 – 4

 are the same as for conversions with 4 filters. 

Filter 5

 is an apodising filter as described above. 

 
For the 44.1k

→

DSD conversion which has 6 filters: 

Filters 1 – 4

 are the same as for conversions with 4 filters. 

Filter 5

 is an asymmetrical design with non-linear phase and no pre-ringing. 

Filter 6

 is a new long filter which has linear phase and pre-ringing. 

 
The best filter setting is a personal choice and may be related to the type of 
music.
