Volume ramp

If we increase the volume from 0% to 100% immediately, this will generate a large spike in neuronal activity (onset response), this can generate a painful sensation. To make the signal feel smoother, the signal should be ramped.

My setup ramps from 70% from 100% in 30s. This reduces, but not eliminates, the effect.

It'd be nice to know what the ideal ramp looks like.
