Jez,

A certain amount of delay is generally unavoidable in any digital signal pr=
ocessing system. If that was not acceptable, you had to listen through an a=
nalog monitor or preamp.

The reason for that is that any modern oversampling A/D and D/A converter e=
mploys an internal digial filter pipeline that always causes some delay. Th=
e minimum possible delay is usually a few hundret samples in both the A/D a=
nd D/A converter (1000 samples at 44.1 kHz would for instance corresond to =
a delay of 0.02 s). There might however be additonal delays in a recorder d=
ue to additional signal processing steps, such as resampling and filtering.

Regards,
Raimund
