just few notes about transferring DAT recordings to a PC...
Many sound boards and external audio devices (USB, FireWire) have digital
IO capabilities to transfer a digital recording to a file.
Though, it is important to carefully verify the digital I/O capabilities of
the board you use: some devices - even expensive - don't perform direct
digital transfer of data but they do perform a real-time sampling rate
conversion (SRC). This might be sometimes useful, for example to downsample
to 44.1kHz a 48kHz DAT recording for CD mastering purposes. Unfortunately,
in these devices, sample rate conversion may occur even if transferring a
48kHz DAT recording to a 48kHz sound file!! This unnecessary data
conversion introduces artifacts that in most cases are not relevant, though
it is preferable to avoid them. To preserve the quality of the original
data the sound boards should lock on the incoming sample rate to transfer
samples to the PC as they arrive, without any sample rate conversion.
Often sound boards' documentation does not provide information about this
feature and only an accurate test can show if SRC occurs or not.
To find cheap cables for digital IO with SONY D7-D8 and maybe others, I
suggest to visit
