If the spike is in a place where there is music (and not just audience noise between songs), I don't like to use gain reduction, either through the Amplify function or the envelope.  You want to reduce the offending clap / stand hit / drunk person / whatever without reducing the music.

So a compressor is the way to go, but I don't really like Audacity's compressor module.  What I've found works better (for me) is starting with the Hard Limiter and softening it a bit.

Sometimes you can just zoom/select and cut it out completely - and not really miss it...depends on the material.

Volt, thanks for the re-post of the Hard Limiter tip. I copied that into my Audacity tips file and will use it. I hate using the negative amplify to do this when music is playing.
music IS love

When you get confused, listen to the music play!

Maybe if it's only a few ms long.  Is that like the opposite of inserting extra frames into movies, a-la Fight Club?

So, using the negative amplification feature on the non-music, crowd/clapping sections is a game changer for me. It can be tough to get exactly right without hearing the change, but it's minimal, and as long as it's not during the music - it does a great job of balancing things out. The hard limiter is ok, but it always created that weird compressed sound to me. This is a much better option IMO.
