No problem on the initial private mail; as I said there, initial results
looked excellent! By now, I have used your advice to make a successful
transfer of 14 segments of F32 wav sound into a lossless 16-bit Flac
file, though each segment got independently normalized resulting in
minor level jumps now and then. I can reduce that next time by converting
the full source file set before segment extraction, but there may still
be slight jumps between files I suppose.

Thanks much; this prevented me from having to tinker with each file in
turn under GoldWave in Windows just to put together the file I wanted.
