The first one is via the Noise Reduction tool. Two options in Audacity remove background noise. Which means, again, installing additional software. So, you’ll have to get a video editor to combine the new audio with the video file and erase the old audio track. Another disadvantage is that even though you can import videos into the program, you cannot export them back as videos. While opening a file in Audacity, watch out for error messages – they should point out the software you need to install. The most common requirements are FFmpeg and Lame. First of all, you may need to install additional software to make the app open your files. 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.
