If you have music that sounds just a bit off, you can fix that with Audacity. Audacity is completely free software; in fact, if you had the inclination, you could play around with the source code that it is made of. With a few simple tweaks, you can take a song with bad volume and make it perfect. Here’s how.
What’s wrong with your music? Is it too loud? Is there too much static? The tempo is too fast? Too slow? Audacity makes it easy to fix all of these problems. Since this is a short article, though, I will focus on removing clicks from the audio. this is a good example problem that can teach you much about how to use the program.
Start, obviously, by launching Audacity. When you first see it, the interface may look a little intimidating. Don’t worry, it’s not nearly as rough as it looks.
your first step will be to import the track you want. That can be done through the File, Import, Audio tool. that will take your clip and put it in a track, which you should see in the big, blue/grey area of the screen.
Now, if you just wanted to alter the volume level of the clip with Audacity, all you would have to do is alter the Gain slider to the left of your track. This would alter the global volume of the entire track. But how would you strip out the clicks from the audio?
Start by selecting the entire track. this can be done by finding the tool that looks like the text insertion cursor in a text editor. Drag your selection from the very beginning of the track to the very end, highlighting the entire thing in blue. Now, to remove the clicks, all you need to do is go up to effects and select Click Removal. Play around with the options here to get the best results. Just remember that, after you click OK, you will have to undo the changes with a CTRL-Z command.
This is the same basic way you can apply other effects in Audacity, too. You can level the audio easily by selecting the Leveller effect, and alter the playback rate with the Change Speed effect.
When you are done, export your work with the File, Export option. If you want to export to MP3 you will have to do a little more work, because, unlike Audacity, MP3 is not free. Don’t worry, Audacity walks you through how to install an encoder, and you won’t have to pay anything.
These are a few simple ways to improve songs. But Audacity is an extremely powerful program for its price. You can alter the volume level of parts of tracks, generate sounds, cut and paste different parts, and much more. So give Audacity a try for your next audio project.
