4DSOUND and SubPac developed a tactile bass application for spatial sound integrating the wireless wearable SubPac M1s within the 4DSOUND system. The low frequencies present in the spatial sound environment are translated into touch by the haptic feedback inside the wearable.

With this application, the experience of bass is naturally extended with physical vibrations anywhere one moves in the room. In combination with a position-tracking system, it can be used for specialised uses of spatial bass, such as personalised experiences of bass, imitation of low-frequency standing waves in space and resonant bass-tones that emerge according to the the distance of listeners in relation to each other.
