Tips for Effective MP4 Audio Normalization

While the process might seem straightforward, there are a few tips that can help you get the best results:

The better your original audio, the better your normalized audio will be. Try to start with the highest quality MP4 file available.
Be careful not to push the normalization too far. You want to balance the audio, not flatten it completely.
After normalizing, test your MP4 on various devices to ensure it sounds good across the board.
Different types of content might require different normalization approaches. A quiet dialogue scene might need different treatment than a loud action sequence.
Always keep a copy of your original MP4 file before normalizing, just in case you need to start over.
