removing static "clicks" from audio
by Gilles Gagnon on Jul 4, 2012 at 6:59:22 pm
In a recording, a few clicks which sound like static somehow made their way into the recording file. I have now idea what caused it. I'm using an external Tascam US-122L as a recording device.
No clicks when I record off my Desktop PC but they appear when recording on my laptop.
But.. I digress. the question is... Is there a free plugin that can be used to remove these?

Audacity has a click remover and it's free (not a plug-in but an audio application). Sony Sound Forge also has a Click and Crackle remover as does iZotope RX2 with it's DeClicker but they are not free.

Thanks John,
I loaded the latest version of Audacity last night, quickly tried but didn't work. I'll try again today while I tweak the settings of the de-clicker.
It's a good one to have in my toolbox regardless. Thanks for mentioning it.

Well... I guess it's a case of "you get what you pay for". ;-) If this is your livelihood, I would seriously consider investing in iZotope RX2. It is an amazing tool for fixing audio in post. You can download a free trial and see if it worked in your case before you buy.

I understand John,
In my case, it was just needed in this particular case doing some audio recording. I can usually clean it up using other methods.
I'll definitely purchase if the need increases.
Thanks again,
Gilles

Another suggestion is to take a slice of audio on part of your video that is clean and paste it over the click. Of course that only works when there is no speaking going on. That has saved me many times.
Recently I had a bad spot with some crackle that lasted only a second or two. The video was on a farm and I added a couple seconds of barking dog over that short section to camouflage the bad audio and it worked like a charm.

Thanks Roger,
In this case it's someone signing so this may work. If I can't get Audacity to remove the noise, I'll use your trick. If I can isolate the click, which is barely visible even on an expanded waveform as it's not a spike, I will cut it out and crossfade the resulting cut.

If you are looking for a sound like the dog barking or any sound at all, you can most likely find it for free at: http://www.freesound.org
I upload sounds there and everyone that does shares them royalty free. It's a great resource.
