INFORMATION PROCESSING SYSTEM, NON-TRANSITORY STORAGE MEDIUM HAVING INFORMATION PROCESSING PROGRAM STORED THEREIN, INFORMATION PROCESSING APPARATUS, AND INFORMATION PROCESSING METHOD

A determination section determines whether or not contact of an object has occurred, based on an orientation, of a controller, calculated by an orientation calculation section. A first waveform generation section generates a first vibration waveform when the determination section determines that the contact of the object has occurred. An audio vibration waveform generation section generates an audio vibration waveform based on a sound signal. An output section outputs the sound signal and outputs a signal representing a combined waveform obtained by the first vibration waveform and the audio vibration waveform based on the sound signal being combined with each other, when the determination section determines that the contact of the object has occurred.
