Abstract
User interface signals representing volume change requests are converted to volume control signals using a mapping. The mapping is overridden (modified) within a given time interval after starting (which includes resuming) playback. During this interval, the mapping for volume decreases is modified so that the resulting volume decreases are accelerated relative to those that would be generated by the default mapping. This allows the user to quickly reduce the volume of the device when begins playing very loud music. The mapping for volume increases can be modified during this interval.
