(...) See (URL) for the .rso file format. It is a modified .wav file. The only facility in the standard NXT firmware for playing sounds of any kind are playing a tone (frequency/duration) or playing a .rso file which has previously been uploaded to (...) (19 years ago, 5-May-06, to lugnet.robotics)

(...) Most of the file extensions on the NXT start with .R and end with two characters which suggest the file type (SO for sound, XE for executable, TM for "try me", DT for datalog, etc...). A .RSO file is a massaged .WAV file. The .RSO file format (...) (19 years ago, 5-May-06, to lugnet.robotics)

(...) Tim, I don't know of anyone who's done this, but I strongly suspect it can be done. and, a .rso file is what they call the robot sound file. Steve (19 years ago, 5-May-06, to lugnet.robotics)
