The analysis shows that, by adjusting the pulsewidth (PW) of a push-pull
symmetric square waveform such that PW = 4.5 tau, the total charge
delivered to the tissue load can be minimised without impacting the
efficiency of the nerve stimulation. Additionally, by minimising the charge
exchange supported portion of the current pulse, which is primarily
responsible for the pH shift and subsequent tissue burning with long-term
use, the latter can be reduced to an acceptable level.
Push/pull audio amplifier [It would be rare to find one that isn't that]
playing a tone to set duty cycle [charge exchange supported portion of the
current pulse] with frequency....same thing.
Amplitude = "intensity" = volume control knob.
Customize the wave form with a graphics equalizer.....put spikes or hard
edges in wherever you want.....or take them out.
You can even be stereo. [Channel A&B ..aka right and left side speakers]

The pulse shape is very similar to that you'd get by putting a pulse
through an audio transformer. And it turns out that there is a study for
that too: http://www.ncbi.nlm.nih.gov/pubmed/12917999. I don't think it
would be too difficult to design a circuit to get the waveform.
