^ By his responses, I think the OP of this thread is saying that the Click Removal tool is more effective at minimizing the claps than the Hard Limit tool. That said, I haven't use the Click Removal tool for claps, I can only speak to how I use the Hard Limit tool, which I've found can be quite efffective in situations where the level of the clap is alot higher than the level of the music.
OK, so the times that I've found hard limiting to be effective is when the clapper is close to the mics and, when looking at the sound signature in your software, you see distinctive spikes where the clap happens. If the level of the clapping does not cause a level spike, in other words the clap level is the same or lower than the level of the music, then the hard limit tool won't help at all.
What you want to do then is determine what are the peak levels of the music and set the limiter so that it cuts off the levels of the clapping so that they're attenuated to about the same level as the music. This won't do anything to eliminate the clapping, but at least it will make the clapping less annoying since the levels won't be so loud on the master recording.
So, if the music is peaking around -10db and the claps peak above that, then set the limiter for sounds louder than...maybe -9.5db.
Now, you can normalize levels on the entire recording and the level of the claps will only be a half db louder than the level of the music, whereas before hard limiting the claps might have been 10db or more louder. I don't like to set the limiter lower than that, because then you're also going to attenuate the peak levels of the music.
