is their a program that amplifies a singan in your computer like something that takes a program and then boosts the signal in your computer to your computer speekers?
Most music and video playing programs have equalizers. the first setting in each setting is something called "pre-amp" that ranges from -12 dB to +12 dB. The higher you make it the louder it will be.
If you use iTunes...
"To open the iTunes equalizer, click the equalizer button in the bottom right corner of the iTunes window."
