General information on filters in Moodle 2.0 can be found at Filters 2.0 and for developers at Filters 2.0.

Add language folder: \lang\en\ and put filter_nanogong.php file with the following content there:

$string['filtername'] = 'NanoGong';

The filter function is wrapped inside a class:

class filter_nanogong extends moodle_text_filter {

   function filter($text, array $options = array()){
   ...
   }

}

Note: The callback function has to be outside this class definition!

$CFG->currenttextiscacheable = false;

is deprecated, outcommented

Instead of the old file.php the new File API uses pluginfile.php.
I uploaded a test file (sentence.wav) as a resource to find out the internal URL Moodle uses for serving this file.
I then added this full URL as attribute to the NanoGong tag:

<nanogong

   caption="Testing NanoGong..." 
   url="http://localhost/moodle-MOODLE_20_WEEKLY/pluginfile.php/130/mod_resource/content/1/sentence.wav"

/>

As the URL is already in its full format I just commented out the following lines in filter.php.

if ($url != "") {

   if ($CFG->slasharguments)
       $url; # = "{$CFG->wwwroot}/file.php$url";
   else
       $url; # = "{$CFG->wwwroot}/file.php?file=$url";

}

This modification does also work:

<nanogong

   caption="Testing NanoGong..." 
   url="/130/mod_resource/content/1/sentence.wav"

/>

if ($url != "") {

   if ($CFG->slasharguments)
       $url = "{$CFG->wwwroot}/pluginfile.php$url";
   else
       $url; # = "{$CFG->wwwroot}/file.php?file=$url";

}
