This paper describes the design of a Calibrated Source (CalSo) loudspeaker created for audio prototyping of a mobile phone. CalSo is used in conjunction with a PC application, which enables the use of virtual audio prototypes for the enhancement of audio content creation of mobile phones. CalSo provides means to calibrate the output of a PC with the loudspeaker itself or with a pair of headphones. CalSo was primarily developed to ensure that the auralized audio output of a virtual audio prototype from the users PC accurately reproduces the audio output of the real device.
