As you probably guessed, you need a microphone to record your voice over. So much is straight ahead. What is not so straightforward is the difference in sound quality that different microphones can capture.

For example, take two vote YouTube videos that I recorded. One was recorded with a computer microphone and the other was recorded with a smartphone. The differences between the two were extraordinary! The person who was recorded with a computer music was very hollow and had no base on it while the one recorded with the smartphone had very solid quality and sounded quite natural.

Now, I can not say that this is necessarily for all smartphones, but I've tried to compare the sound recording quality of my own device to all the other equipment with the recording capabilities I have and somehow the smartphone comes out at the top every time. It's even better than my HD video recorder. Try all the microphones you own, and if you do not have one then you can easily purchase a computer microphone from staples or any other office / power outlet for about $ 30.

Here's how to remove unwanted sounds from your voice over.

Free audio editing software like Audacity comes with already great tools installed that can help you remove unwanted background noise from your audio recording. However, there are some things you can do before and during the process of recording your voice over which makes the job a lot easier.

Record your voice over in a room without existing background noise.

Leave 10 seconds blank space at the beginning of the recording so that you can give an example of any background noise without your voice in the way.

Keep an even distance from your microphone during the process of recording audio from your computer.

Avoid taking deep breaths. You can always delete these while editing, but the less you have to remove the easier your job becomes.

In Audacity, mark the blank space in the first 10 seconds of your voice over. Now select in the upper field Effect -> Noise Removal and click the button that says Get a Noise Profile. Audacity has now received a sound sample from your recording. Now highlight the entire clip (CTRL + A) and go to Effect -> Noise Removal. Now press OK and voila!

How to use a compressor to ensure the same volume of sound throughout the recording.

Each voice recording will have its high volume points and its low volume points. It is the compressor's job to smooth these points while keeping your noise consistent.

Here's what you need to do. In Audacity, select the entire clip (CTRL + A) and then go to Effect -> Compressor. You should see a line chart with some options, for example. threshold, noise level, ratio, attack time and maturity. Even if you do not fully understand what these options do, the default settings will generally dramatically improve the overall quality of your voice recording. But here are some basic explanations and recommended settings:

Threshold: This is the most important setting. It tells us that Audacity applies compression and does not let the volume go slightly higher than the point you say it should go. Set this between -14 and -30. Relationship: How much compression will apply? At 2: 1, your nails will be halved. At 3: 1, they will be cut to one third of their original size. Noise Floors, Attack Time, Maturity: Leave these as they are.
