Santa Cruz SPDIF Question

Archived from groups: rec.audio.tech (More info?)

I use a Turtle Beach Santa Cruz PCI card (Win 2000) to output SPDIF to an
outboard DAC, then on the the main studio monitor pre-amp.

There are several places (windows) where volume controls appear, the Santa
Cruz mixer/volume control, and player, i.e. Winamp.

Can I assume that an all digital path is taken from source (.wav) file to
DAC? This would imply that volume adjustment are done digitally. If so, I
am very curious just how this is accomplished.

My mind wanders into thoughts of also performing equilization this way,
which currently is only available on the "audio" out jack (analog) of the
Santa Cruz which implies it is doing DA first, then EQ.

Any thoughts or information about this would be greatly appreciated.

By simply throwing away the lower bits if information, I imagine.

Windows Media Player has a graphic EQ (View/Enhancements). If you
want to get further into digital audio manipulation you need to move
up from a simple player to a wave editing program.
