Hi all, I am 63 years young and new here and to audacity. I watched lots of YouTube tutorial videos before downloading and trying to create a record, and the tutorials included removing clicks. I have created a 3:22 min audio that was created by combining 4 different tracks. I had no problems combining the tracks, but where I have added the 2nd, 3rd,and 4th track, there are audible clicks that are also visible in the audio clip. I have tried using the click removal tool, but to no avail. The message I get back is that the “Algorithm not effective on this audio. Nothing changed”
I have a couple of screenshot where the click is visible but i do not know how to share them with this post. Sorry for that but if someone could explain how to share those three screenshots I will post them.
Any help would be greatly appreciated as I am trying for the last two days to remove the clicks by re-combining the tracks (the clicks are still there) by deleting the part (the click is still there) and by using the click removal tool but whatever I do I be unable to remove the clicks.
DC offset can also cause a click when it kicks-in and kicks-out. (The Normalize effect has offset removal, and you can un-check normalization if you don’t want to change the volume.)
Or when you are “splicing”, a crossfade almost always takes care of any issues and makes a smooth transition. You can make a short crossfade of a few milliseconds if you don’t want to hear it as a crossfade.
P.S.
As you may know MP3 is lossy compression. When you open an MP3 in Audacity (or any regular audio editor) it gets decompressed. If you re-export as MP3 you are going-through another generation of lossy compression and some “damage” accumulates. You may not notice any quality loss, but try to minimize the number of times it’s compressed/re-compressed. (i.e. Save any temporary files as WAV or FLAC.)
Thank you, I will try this allso I’m not sure what DC offset and splicing or crossfade mean or do. By cutting the waveline at the zero-crossing I do believe I know what you mean and have given that a try however i actually intoduced a new, also not at audible, click and every time i try to cut the new click I just seem to introduce a new click. I do zoom in so that only the part with the click is visible on the screen to make sure that i cut on the zero-crossing line but i still get a new click. I will have a look on YouTube again to see if there are some more tutorials that do explain the DC offset and crossfade so i know what they are. Again, many thanks. I really appreciate your input.
