Translating user interface sounds into 3D audio comprises: receiving an audio request call from a process relating to a user interface event; converting the audio request call into a position in 3D audio space representative of the process from which the call has been received; and playing a corresponding sound in a surround sound system in the position in 3D audio space. Each open application in a graphical user interface may be provided with a sound space, in the 3D audio space, from which any event sounds are played.
