"The Neuros Audio Computer is not only an mp3 player. It is an mp3 player on a high dosage of caffeine. One of my favorite features on the Neuros is the HiSi(HearItSayIt). You may hear a tune on the radio while listening to the Neuros that you can't get out of your head. You must find out the name of the song. The Neuros comes to your aid. Click the orange button on the unit and it will record a 30 second sample of the song. The Neuros uses advanced audio footprint technology made available by Relatable to not only identify the song name but the artist as well. Next time you synchronize your Neuros with your PC it will identify your HiSi requests."
