 * Audio files of type *.ogg* are much smaller, but use considerably more amount of CPU power to play back, so only a few can be played back (especially on mobile!). This format is usually best for music or long sound effect sequences. It also works well for voice at relatively low bitrates.
 
 Keep in mind both .wav and .ogg generally don't contain looping information, so this information must be set on the import options of each:
