 gsmrec-dump		See Binary-file-format article.
 
+pcm16-check13		This program reads a 16-bit linear PCM recording file
+			(raw BE by default, or raw LE with -l option) and checks
+			if the 3 least significant bits of every sample are all
+			zeros.  All linear PCM samples consumed or generated by
+			GSM codecs are only 13 bits wide, left-justified in
+			16-bit words, and so is output from G.711 A-law decoding
+			- thus it is useful to be able to check if a given file
+			in 16-bit PCM format is purely 13-bit or not.
