Hi Gus,

As long as we are talking about the theoretic principles of digital samplin=
g, the type of interpolation should not be an issue. However, there might b=
e poor implementations of D/A converters or sample rate conversion algorith=
ms that suffer from inappropriate interpolation algorithms. But as far as I=
 understand, this wouldn't be the problem here.

 you get the gist.....

Yes, this is true. However, this not mean that there is anything wrong with=
 signals that are close to the Nyquist frequency. Increasing the sample rat=
e would just increase the (analog) bandwidth of the recorder, which would o=
f course also provide more temporal details on the waveform.
