How would 10 or 12 bit even be packed? (It can't be packed in WAV, right?) Anyway, the FLAC specification has room for any bitdepth between 4 and 32 bit, but I'm not sure whether the reference encoder accepts those, I never tried.
10 bit sample: 0111111111; Requires to be placed in a 16 bit container for WAV, i.e. 0111111111000000. As I said previously, WAV requires sample sizes to be an integer number of bytes.
