A method of neurostimulation includes delivering an electrical signal to a plurality of electrodes (215A, 215B) connected to a patient. The electrical signal is characterized by an amplitude and a carrier frequency. The method includes modulating an electrical signal based on an audio waveform. In some cases, the modulation may include modulating at least one of an amplitude and a carrier frequency based on the audio waveform. A neurostimulation device (200) comprising first and second electrodes is also disclosed.
