You’ve at least taken the first step: recognizing how important sound is.
As others have mentioned, there’s no simple answer to your question.
However, here are some things to consider:
— You gotta know what “good” sound is to know what needs to be done to get it.
— “Good” sound starts in the field, just like “good” video.
— High quality microphones and associated systems tend to get rather costly. Sometimes renting is a good option. Knowing how to use them really well takes training or guidance from an experienced pro.
— Having an accurate system to monitor the sound is an essential part of the process, and such systems are never cheap. I use a pair of Tannoys. If I had to do it again I’d get a pair of Genelecs.
— Often overlooked is the room you’re working in. Good speakers won’t perform well in a bad room. Consider the room as an integral part of the equipment.
— Some controls to consider: compression for some voice tracks. Equalization. Mixdown levels.
— Lastly, never mix on headphones. Always use speakers. Headphones will give you a false audio image and you’ll end up with a weak or inaccurate mixdown.
