I use the soft knee limiter at 12db with the attack, sustain and decay values configured to something like 3ms, 5ms, and 3ms with lookahead enabled. That will catch the impulses and drop them down with minimal effect on the surrounding music. This should apply to any editing tool that allows configuration of the limiter parameters.
The behavior I see with the usual default settings is that when an impulse is detected, the clap triggers the limiter. The attack is too slow to apply the complete 12db attenuation to the impulse but then the limiter stays applied long past the impulse. That affects the sound following the impulse such that the entire selection was affected and there seems to be breathing in the levels. The default settings cause the affected channel to be lower than the other channel so the entire image shifted toward the untreated channel. When I zoom and select just the impulse, the attack is so long that it barely affects the clap if at all.
With the configuration values suggested above, the limiter kicks in quickly and drops away quickly so the surrounding music is hardly affected. I found this very effective for cleaning up a show in which there was a clapper in one channel that was louder than the music. I was able to drop her down so that she was about the same volume as the rest of the crowd noise and I operated on just that channel. With the limiter settings I chose, I could not hear any difference in the average levels of the two channels.
In the cases where the clapping was after the music, I was able to select a wide area and apply my settings. However, where the clapping is coincidental with the music, you will need to selectively apply the limiter to the impulses you want to remove. Otherwise the impulses of the music will be affected too.
To get a feel for this, zoom into the waveform and measure the width of the clap impulse. You will find that it is a few milliseconds only. Select about 400 ms centered around the clap and then play with the limiter settings. You can dail in the settings with a few trials. Then apply the limiter across a wider selection area.
