I *hope* that's not the reason Linn went with WMAL instead of FLAC! are the tracks DRMed? anyway I am considering using one of the reserved codes (there are 3 left) in the frame header for 88.2KHz and letting it be in the subset. as far as FLAC is concerned the sample rate makes no difference to anything, it's just a number. the constrained set is mainly a concession to hardware makers to not have to support every oddball rate to be subset compliant. also in 1999, I didn't really know how things would shake out with regards to what rates would be common.
