Removing clapping from an audio recording

Thanks kozikowski for the advice. I tried to use the “Remove Click” utility with different parameters. I received the best results when I set the threshold to 150 and the max spike with to 40. I didn’t really understand how this effect works so I will appreciate it if you could explain to me.

Try this: Missing features - Audacity Support

When I tried to run the effect on the same sample for a second time the change was less noticeable and on the third time there was barely any change. If I run the effect a few times can it damage the sample?

Probably. The test is whether you can hear the damage, and if the “clap-reduction” is worth the damage.

I added an image of the before and after the click removal effect. Is there a way to make the clapping spikes even lower without lowering the volume of the music?

Looks like you’ve been fairly successful. Read the wiki article and then try different settings on the same chunk of audio to see what works best.

You’ll never get all the claps out. As Koz is wont to say “it’s like trying to take the cream out of the coffee”.

There’s another option, but it’s not free. There’s a program called “ClickRepair” that was designed specifically to take the clicks and pops out of vinyl and shellac (78 RPM) records. You might be able to coax it to do a better job of removing the claps than Audacity’s Click Removal tool can. If you’re interested just Google “ClickRepair”
