A system to control an audio signal that is to be provided to a subject wearing a leg prosthesis in response to changes in motion patterns of the subject, the system comprising: one or more processors; one or more memories; a leg prosthesis having a socket portion and a lower portion connected by a knee joint, the leg prosthesis including one or more kinematic, kinetic, spatial and/or temporal sensors; characterized in that: a sensor module stored on the one or more memories and adapted to receive sensor motion data of a subject wearing the leg prosthesis from the one or more kinematic, kinetic, spatial and/or temporal sensors and extract motion characteristics from the sensor motion data; a motion analysis module stored on the one or more memories and adapted to cause the one or more processors to analyze the sensor motion data and determine an amount of deviation of the sensor motion data from baseline motion data for each of the extracted motion characteristics, wherein the determining produces a set of deviated sensor motion characteristics; a perceptual mapping module stored on the one or more memories and adapted to cause the one or more processors to map the set of deviated sensor motion characteristics to one or more audio features of an audio signal to be provided to the subject, wherein the mapping includes accessing a lookup table that associates various controllable audio features to various motion characteristics, wherein the mapping produces a set of mapped audio features of the audio signal; and an audio effects module stored on the one or more memories and adapted to cause the one or more processors to adjust values of each of the set of mapped audio features based on the amount of deviation of the set of deviated sensor motion characteristics, wherein the adjusting produces an audio signal effects model to be applied to the audio signal. one or more processors;
