If they are claps, you can use a click reduction, like Click Repair (DeClick):

that does a really good job of removing record pops. Single hand claps are so similar that it works well on those too. It is adjustable, so if it messes too much with the audio, you can lower it, until it reduces the claps & not affect the frequencies overall...

If you're talking about screams/whistles, well, there's nothing but manually selecting each scream/whistle, & either limiting it, or lowering the volume & then listening back & forth, to make sure you didn't get it sounding artificial...

Click Repair has a free trial period, so if you want to play with it, try it out. It's not too expensive if you find it to do what you want. I used it to clean up a recording that had thousands of singular handclaps & it cleaned them up nicely with out any noticeable side-effects...
