 @return threshold 

   * Make a dead map based on the gain of the channels.  If the gain
   * of a paraticular channel falls outside the range specified by @a
   * min and @a max, then the channel is marked as dead.
   *
   * If the argument @a dead is non-null, then the map passed is
   * modified.  That is, channels marked as dead in the map will
   * remain marked.   Channels that meat the criterion (gain outside
   * the specified range) will in addition be marked as dead.
   *
   * If the argument @a dead is null, then a new map is created and a
   * pointer to this will be returned.
   *
   * @param min Minimum value of gain for a channel before it is
   * @param max Maximum value of gain for a channel before it is
   * marked as dead.
   * @param dead If non-null, then modify this map.
   *
   * @return A pointer to possibly newly allocated dead map.
