Well, sox can do it after all, at the command line of both Linux and Windows:
... will concatenate the three input wav files and produce a flac of compression level 5 (0 is least compression, 8 is highest). My faulty 7.3GB wav was replaced by a 3.4GB (compression level 8) or 3.9GB (level 0). Level 8 takes more time to produce, and the size difference in my test is not very significant so I've opted for the default 5; YMMV. Regardless of the compression level used, flac uncompressed file data will be identical to the original.
In both Linux and Windows, too, Audacity can export a selected assembled track in flac; compression level is set in the export options.
I'm working on a Linux bash script that will handle the trailing "a"s that USB Audio Recorder PRO produces in successive filenames so correctly sequencing a collection of 2GB files in a folder should be easier. I suppose a Windows batch file could do the same.
