Techniques (methods and devices) for neural stimulation through audio with dynamic modulation characteristics are disclosed. The techniques include receiving a mapping of sensor-input values and modulation-characteristic values, wherein each sensor-input value corresponds to a respective modulation-characteristic value; receiving an audio element from an audio source, wherein the audio element comprises at least one audio parameter; identifying an audio-parameter value of the audio parameter; receiving a sensor-input value from a sensor; determining a sensor-input value based on the sensor-input value; selecting from the mapping of sensor-input values and modulation-characteristic values, a modulation-characteristic value that corresponds to the sensor-input value; generating an audio output based on the audio-parameter value and the modulation-characteristic value; and playing the audio output.
