Monitoring if audio's peaking?

Hi I'm at the phase of development where mastering the in-game audio's become main priority. I see myself struggling with balancing all the music and SFX together since I can't seem to find any good tools for monitoring when the audio peaks (essentially when the volume levels would end up in the red in audio/video editing software)? Is there any way to get data on this rather than just having to do it all by ear?

Thanks.
