Hello all!

I am currently experimenting with new ways to edit the audio of my videos. I've edited an online action/comedy film series for years, but the audio has never been that great, so I'm looking to expand my audio-editing abilities.

My biggest question is this: What's the best way to edit a video so that the dialogue (whatever the characters are saying) is loud enough to hear over top of the music, but the music is still loud enough to create suspense/emotion?

I'm very new to editing audio; I know next to nothing about compressors, equalizers, etc. In the past, I've just lowered the volume of the music in order to make sure you can hear what the characters are saying in my movies, but I feel as if this makes the music too low and takes away from the suspense/drama that's occurring in the scene. I'd like to learn more about alternatives to simply lowering the volume of the music. I found this video on YouTube about using an equalizer to make the music sound loud while still being able to hear the character dialogue:



However, is this standard practice, or do better methods exist? (I've tried this out - it works well sometimes, but other times it makes the music sound very strange).

If anyone would like to recommend any books, webinars, professional training, etc., I'd definitely be willing to check that out. I've been searching online for days, but can't find anything good!

Thanks so much for the help!
