I have some old ADAT tapes and I would like to archive the tracks on them to my computer. I plan to have an ADAT recorder connected via an ADAT/Lightpipe cable to an internal PCI/PCIe card or to a break out box that is connected to the computer via firewire. If I play the tapes and record the tracks to disk with Ardour, will they be transferred losslessly or is there a digital <-> analog conversion happening somewhere in the chain? If there is a conversion happening, is it anything to be concerned about or would it be high quality enough to not be noticeable? Thanks for any feedback.
