Re: Quest for a mobile recorder - how manufacturers do designs...

[kkissinger@kevinkissinger.com]

The reason for this is that after the D/A converter the signal (which  
is a series of discreet stepped voltages) is passed through a low-pass  
filter (to smooth out the edges).  At 192khz, the cutoff frequency is  
high enough that it won't cause any noticeable effect on the audio  
signal.

All, the same... I work at 48khz.  The bit depth seems to make a  
bigger difference than the sample rate (at least for my work) so I run  
at 24 bit, 48khz.

The reason I run at 48khz is that my Kurzweil's (K2600) ADAT output is  
at 48khz.
