   I repeated this message for the benefit of all concerned.   
      
   We never addressed the software you use. Some software is not licensed to   
   pickup signals   
   for recording because they want you to pay money for that. You can download   
   several   
   free audio recording or dubbing software apps, record in .mp3 at the desired   
   rate, and   
   then copy and paste the completed file over to NextRadio's output folder for   
   audio so   
   you can play it back.   
      
   Or you can record it in 16 bit Stereo wave format (.wav) file, convert it to   
   .mp3 format   
   you desire to convert it to with a convertor. Then dump the file into   
   NextRadio's   
   output folder to playback the finished .mp3 file. In this way, you can bypass   
   the   
   software you speak of stringent requirements and pedantic quirks.   
      
   FYI, sometimes, there is a DRM (Digital Rights Management) on these files or   
   software   
   that play them to prohibit copying copywritten files. DRM is a form of a   
   "copy" guard,   
   again because it boils down to the fact that they want you to pay money to get   
   the   
   composite signal that comes from them. I just provided you work arounds without   
   the cost and the hassle; I also warn that this post is for educational   
   purposes only   
   regarding recording and conversion of signal and is not an encouragement to   
   violate   
   any copyright or infringe upon anyone's work in any other form otherwise.   
      
   Good luck,
