Re: SPDIF signal enhancers

2004-02-11 by vibesart

Yo rEalm -

another POV on this (my own, altho I am not glued to this method...)

the quality of Normalization does depend on the software that is being
used to Normalize, and of course we all know that in the N process the
audio takes a hit, so to a degree one has to weigh which hit they
prefer - N or A/D.

I find myself continually more drawn to an analog re-recording of the
XL7 - and have not found noise to be an issue. For me the analog
re-recording gives synths a bit more definition and I do like the
sound of the Emu D/A's - but of course this method does require good
A/D's and a mixer or mic pre or other signal booster, and it does add
a coloration of the orginal sound. 

That said - depending on what DAW software is being used one should be
able to boost the XL7 spdif signal before/during the recording.

I hear time and again that the optimum place to aim for in a 24 bit
recording of individual tracks is -6 db (Bob Katz, the Metric Halo
guys et al), for whatever that is worth.

rock forward
