Have DIY project with EFM data to transfer to a PC. It's basically 16-bit 44.1khz cdda before it's decoded into proper CDDA form (or before SPDIF).
Have software EFM converter, written in python by someone else on these forums, which I think should properly convert the EFM into proper 1's and 0's (or raw CDDA or bin). But have no way to test since I don't have a standard serial to usb interface (just plain ground and data cable).
I'm thinking to transfer the EFM through a high speed serial port in Linux, and do something like 'cat /dev/ttyS0 >> /tmp/data.efm', but I'm not sure what the best serial to usb choice may be.
Does anyone have a suggestion?
