Libgdx provides cross-platform audio playback for prerecorded audio files of the following three supported file formats:
There are two interfaces called
Sound. They serve two different use cases of playing back audio files. In terms of Libgdx, sounds are audio files that usually play no longer than one second; think of laser or machine gun sounds. 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.
