For those new to Audacity or experienced users looking for tips, this guide will help you diminish and even eliminate white noise in recording sessions.

1. Set Up Your Recording Environment
   Before even opening up Audacity, take care of your recording environment. Find a quiet place, away from external noise sources such as people, traffic, or appliances. Close windows, doors, and make sure the computer's fan, if noisy, isn't prominently heard in the recording. Setting up proper acoustics with foam panels, curtains, and rugs can also help absorb unwanted sounds.

Select the appropriate recording device and make sure the input volume is set to the sweet spot where it will capture your voice without distorting it or picking up excessive background noise. Test recordings are always useful in finding this spot.
