Q: Will all (at least all widely used) 'lossless' audio encoders abort with the appropriate error message if the user tries to feed unsupported audio? Or is there any which will discard channels, downsample, crop bits or just produce nonsense?
The reason why I ask, is that this forum fairly often gets the n00b question of whether 'lossless' is indeed lossless -- and get no more than a simple 'Yes' (or 'Yes, thread closed'). The devil in the detail is hardly ever mentioned, and most users will anyway never encounter that mismatch. But if the situation is 'in the few instances where the usual answer is inadequate, the encoder will warn the users rather than eating audio information', it would certainly be A Good Thing. -------------------- geocities.com/hydrogenaudio: http://goo.gl/tqYZj

FWIW, AFAIK, neither flac.exe nor foobar2000 warns the user when encoding floating-point lossless sources to FLAC. (FLAC does not support floating point so an implicit conversion to 24-bit fixed point is necessary.)
