How to clean up a voice track or narration track in audacity
One of the best ways to improve your home videos whether they are of family events, outings, or even videos you are making for online consumption is in the area of audio.
There is an old saying that the most important part of video is audio and in this case you can make your videos more watchable by making them more… listenable! (OK! I know that’s not really a word!)
Quite often when you are looking at other peoples videos you may have noticed that although the video itself seemed quite OK, there was something that seemed to be annoying about it or some way that it was failing to hold your attention.
The techniques apply to any voice recording you have done regardless of the source but before that always remember when you are recording a voice to set your device at the highest possible quality.
Some devices don’t offer this but many do, so take the time to go into the settings of whatever you are using to make sure you are getting the best audio quality you can.
Once you have your recording we are going to use a free audio editing software program to polish the sound file you have, so we need to get that file isolated and into a format suitable for editing.
If you have recorded a voice track on your computer this is simple because you will already have a single audio file and most likely it will be in the .wav format that we need.
If you have used some other kind of system and do not have a .wav file then you can get a free audio converter here that will do the job, or just Google for one.
Because we are going to edit the file and are also going to be adding that file back to a video project it is very important to stick to the .wav format.
If you are dealing with a voice track from one of your existing videos simply load the video into your video editing software then go to the output – sharing – distribute part of the program and choose to output the file as a .wav audio file.
One you have the sound file you will need another free software program called Audacity which you can download for free here: Download Audacity.
Now that we have Audacity installed, open the program and load your audio file by selecting “File” then “Open” and navigating to where you put the audio file.
Audacity will give you the option of either directly editing the original file (faster) or making a copy of the file and editing the copy (safer).
That way I always have the original to go back to if I mess up and I am not getting Audacity to do anything extra that could lead to problems.
It would be worth anyones time to delve further into learning how to effectively use Audacity for all parts of your video soundtracks. No 1 data recovery software Cleaning Up Your Voice Track
Once you have chosen the method of editing, the file will load into the program and be displayed as a waveform representing the sounds within the file.
In the example track I have used the mouse to select a portion of the file but very often there will be a silent “lead in” at the front of the audio file you could also use.
Now go back and select Effect, Noise Reduction again and the same dialogue box will open only this time, check the bottom of the box to see that (1.) Remove Noise is checked then hit OK.
It will immediately run and you will notice that the areas where there were no vocals before have now become much thinner indicating the reduction in noise.
What you may now notice is that the small areas where you previously removed noise have now kind of fattened up a little because of the Eq changes.
If the Eq has raised the noise level to a noticeable degree then re-do the noise removal step once more for final clean and you should be done.
