The 16bit/48,000 kHz wavs couldn't be encoded by the program though.
I have only ever used EAC to encode wavs so I really am not sure what to use to do this! I DO use Foobar2K for playback on my PC, but I didn't know it could encode flac files as well. Some of you are mentioning that I could use it to encode these higher sample rate wavs. Is there a website I could visit for explicit instruction on how to do this? Foobar seems complex and I have been able to get it looking pretty using 'Columns UI', but beyond that the program is a mystery to me!
[..] you won't lose your original WAVs in the progress (hopefully?).
