The popularity of the car led to a great improvement in auto radio，and the rapid development of the mobile Internet can give to radio a new lease of life. A wide variety of audio software enables us to listen to the world through mobile phone apps，such as listening to a book，listening to music，listening to audio information，obtaining education through audio，and taking UGC classes. Such information is available by push，on-demand，and in personalized forms. These colorful audio apps are being widely welcomed by users. Currently，the audio quality of phone software is limited，copyright issues exist，and government has to face regulatory difficulties. These problems need to be resolved.
