Sync voice with gamepad?

How can I synchronize my audio track (recorded with Audacity) and the gameplay (ps4 gameplay recorded with Elgato Game Capture 30 FPS), I always clap on the audio track, but that doesn't work with gameplay, how can I set such a marker for myself? Do you have an idea, thank you in advance.

Hit a button loud enough for the microphone to hear. Then you can synchronize the in-game action with the attack in the sound track.
