 /*
- * This program reads an extended-libgsm binary file, dumps every frame in
- * human-readable form just like gsmrec-dump, but then also passes it through
- * our GSM FR decoder (libgsmfrp+libgsm) and looks for the highest-magnitude
- * PCM sample in the decoder output.  This maximum output sample magnitude is
- * reported after the dump of each input frame.  This program is intended to
- * serve as a debug aid, for troubleshooting of our libgsmfrp+libgsm stack.
+ * This program reads an extended-libgsm binary file (which must be in FR
+ * codec format, not EFR) and performs the following processing, in this
+ * order:
+ *
+ * 1) dumps every frame in human-readable form just like gsmrec-dump;
+ * 2) passes the frame stream through our DTX Rx preprocessor;
+ * 3) dumps the output from the preprocessor;
+ * 4) feeds this output to the standard 06.10 decoder (libgsm);
+ * 5) finds the highest-magnitude PCM sample in the decoder output and
+ *    reports this maximum output magnitude.
