Audio files used as Sound objects are loaded and decoded so that they can be directly sent to the audio device. Obviously, the decoded audio data kept in memory can heavily increase the overall memory usage. On the contrary, audio files used as Music objects are streamed, which means that only the necessary portion of it is decoded and held in memory. Therefore, Music objects should be used for playing long audio files like background music.
Music objects may require more CPU cycles because the streamed audio data needs to be...
