That is a statement of opinion rather than fact but I won't go into
that here.

However, there is a way avoid that feature of libsndfile by avoiding
the use of floats during the conversion. For instance, when convering
from one format to another, sndfile-convert does this:

	if ((outfileminor == SF_FORMAT_DOUBLE) || (outfileminor == SF_FORMAT_FLOAT)
			|| (infileminor == SF_FORMAT_DOUBLE) || (infileminor == SF_FORMAT_FLOAT)
			|| (infileminor == SF_FORMAT_VORBIS) || (outfileminor == SF_FORMAT_VORBIS))
		sfe_copy_data_fp (outfile, infile, sfinfo.channels) ;
	else
		sfe_copy_data_int (outfile, infile, sfinfo.channels) ;

That is the second path (sfe_copy_data_int) would be used for FLAC
-> CAF and CAF -> FLAC conversions.
