Abstract: A personal training device is provided for a participant of pace-based physical training. The device includes an input for receiving an input signal indicative of a pace of the participant, and a comparator coupled to the input for comparing the pace of the participant to a predefined criteria. The personal training device further includes a training partner positioner for generating a position of a virtual training partner relative to the participant based on an output of the comparator, and a training partner audio source for providing audio representative of sounds from the virtual training partner. Still further, the personal training device includes a spatial audio processor for producing a multi-dimensional audio signal comprising the audio from the audio source, the multi-dimensional audio signal providing the audio at a spatial location represented by the position generated by the training partner positioner.
