Dynamic Voltage Rail Audio Amplifier

The goal of this project is to create a high-quality, power-efficient audio amplifier. Most modern audio amplifiers use a constant amount of power regardless of the signal that is being amplified. This means that both loud and quiet portions of the audio signal require the same amount of power to amplify. The idea for this high-quality, power-efficient audio amplifier is that the quieter portions of the audio signal can be amplified using less power. This will be achieved by first analyzing the audio signal and controlling the power source based on the signal’s needs. Therefore, louder parts of the audio signal will use the typical amount of power, while quieter parts of the signal will not use as much power. When comparing a standard audio amplifier and the high-quality power-efficient audio amplifier, the average power usage for the power-efficient amplifier should be less than the standard amplifier
