Sound is low

After I record audio, I can barely here it in Audacity. What can I do to have the sound be louder? I want to produce audio that is loud enough. Running Windows 7 home. Audacity 2.1.1, exe. Thanks for your help :smiley: !

We have no idea what you are doing, other than trying to record something, with something connected in some way to your computer. Pleas give more information.
