Rockbox allows recording (eg from vinyl) of 88.2KHz wav files on the iaudio X5L. These sound absolutely superb, and oggenc-aotuv451 gives great oggs from them. But could someone please advise on how they can be converted to a lossless compressed format like FLAC? Preferably using linux programs. Do they need to be resampled to 96KHz, and if so how is this done, please?
Many thanks.
