RSO files are an audio format used by Lego's Mindstorms NXT system. The program lets users design custom built robots using the popular Lego building blocks. By converting MP3s and other audio files into the RSO format, users can add personalised speech, sound and music to their robot's soundtrack. Unfortunately, it is not possible to convert directly from MP3 to RSO, so files need to first be made into the WAV format, which is easily then made into RSO.
