Current Characterization Application Note
... In order to minimize ripple voltage, a 0.1uF capacitor should be placed on each VDD and VDDQn input, as close to the pin as possible. VDD pins that are close together may share a bypass capacitor, but VDD should be isolated from the VDDQn inputs. Use of the recommended bypass capacitors will reduce ...

Audio power
Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts. The electrical power delivered to the loudspeaker, together with its sensitivity, determines the sound power level generated (with the rest being converted to heat).Amplifiers are limited in the electrical energy they can amplify, while loudspeakers are limited in the electrical energy they can convert to sound energy without distorting the audio signal or being damaged. These power ratings are important to consumers finding compatible products and comparing competitors.
