Conversion of n3r files to mp3 file format

It looks like that you can use WV-ASM200 software from Panasonic for export of .n3r videos to standard MP4 format and then convert that further to MP3 should you need it. Unfortunately, there doesn't seem to exist any converter that offers n3r to mp3 conversion and overall the options for n3r export are limited.
