However, there are a few difficulties you can face. The main advantages of Audacity are that it’s free and has plenty of audio-editing features. The app’s interface may look a bit confusing for a beginner, but there are many tutorials online that will explain every aspect of the software in detail. The software lets you upload or record audio and then edit it: add fade-in and fade-out, change speed and tempo, normalize the sound, reduce echo, and make the sound cleaner.
Audacity is free noise reduction software for Windows, Mac, and Linux operating systems.
