Found an answer to my problem. It’s from the following web page: http://transom.org/2013/lost-and-found-files/
Below is the part that I used. Note that Start offsets of 0 and 1 gave me nothing but static. But I kept trying and a start offset of 2 worked perfectly. I also had to change the defaults to match my recording parameters of 48,000 sample rate and 24 bit record format.
Tip: Set the Amount to Import to less than 100% until you find the right settings. It won’t take as long on each attempt. Then once you’ve got the right settings, use 100%.
"(S)ome of these problems can be fixed with the free audio editor called Audacity. Audacity will run on many operating systems, and is a small and efficient program, so it’s handy to keep around even if it’s not your primary audio editing tool.
Trying to import the corrupt file into Audacity as an audio file crashed the program, but there’s another option: to import as Raw Data. (File>>Import>>Raw Data…) It’s important to know something about the file when importing as Raw Data. You will be presented with an import dialog asking for the sample rate, the number of channels (one for mono, two for stereo, more for interleaved multitrack files), the kind of encoding (in this case, 16-bit PCM). It will also ask for an oddly-named parameter called “Little-Endian” or “Big-Endian.” The disc formats that most current field recorders use, FAT 16 or FAT 32, write WAV files with accompanying metadata at the end, known as “Little Endian.”
There are a few other settings, but it’s usually best to try the defaults first and see what happens. In this case, it worked fine with the default settings, but if the file did not import correctly, it’s worth trying some variations in the start offset value. If the file opened, but was full of static and other noise, try again with the “Start Offset” set to 1 sample. Once the file is successfully imported, you will have to Export it as a standard WAV file in order to re-write the correct header data. Don’t just hit SAVE in Audacity, that will merely save your session information, you must Export to make a new file."
