How to Edit Audio

Last Updated: May 6, 2021

Digital audio editing technology has created many ways to edit audio. While professional studios use specialized equipment such as studio microphones and mixing boards to create sounds of higher quality, basic editing can be done quite easily with just a virtual studio installed on a home computer. The basic features of the sound editing software remain the same.

Installing Sound Studio Software

1
Install a software that can edit sound on your computer. You can purchase a CD or download the program from the Internet and just follow the steps in the installation guide for that program. There are many programs available but here are some of the popular ones that you may want to choose from.
- Audacity: an open source software that can record and edit multiple tracks. It also has a very effective noise removal function to remove hissing, static and humming by simply selecting a sample of the noise and then removing it from the whole track.
- Power Sound Editor: can record and change tracks that need to be mixed with other parts of a musical composition. You can also alter the audio data by adding time-shifting effects such as Echo, Chorus and Reverb. Power Sound Editor allows you to easily share your edited audios over the Internet or through email. You can also burn finalized files onto a CD.
- Mp3DirectCut: specializes in recording and editing MP3 files. This file format is ideal for someone who wants to compress files to smaller sizes.
- Wavosaur: specializes in capturing and processing WAV files. It offers real-time effects so you can hear what the effects sound like while you are recording the audio. Wavosaur also supports MP3 format.

Question

How can I fix an audio recording that has too much background noise without affecting vocals?

Community Answer

To do that in Audacity specifically, you have to select a part of the video where you don't speak, then go to "Effect." Next choose "Noise reduction," and click "Get noise profile." Then you use CTRL+A to select all of the recording, and go again into "Noise reduction" and click "OK." Be sure you have selected "Reduce."
Question

How can I choose one section of a voice recording file?

Community Answer

If you want to keep the track you're working on unchanged, you select the section you need to extract, then you go to Edit--> Copy and open a new file in File. Then paste that file in.
Question

How do I remove the noise that sounds like somebody is walking on plastic, and how do I fix voices that are too close to the microphone?

You either have to resize the length of the microphone to reach a point, or you have to record while they are away.
