Amplify Audio Files
An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals composed primarily of frequencies between 20 - 20 000 Hz, the human range of hearing) to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain. The degree to which the amplifier magnifies the low-level input signal compared to its output signal is the amplifier's gain, and it is expressed in decibels (dB) because it's a ratio of the amplifier's output divided by its input.
If you are trying to get more volume when playing music from your desktop while you find the volume control on the speakers all the way up, same with the volume control in the control panel. Is there any way to increase the volume output? Use the amplifier in MP3 Editor for Free.
