A lot of people have to realise the fact, that software and automation is replacing traditional forms of music producing gradually. Some people say it is bad, but I try to see the advantages. If you are not able to get a good sound, try out online mastering platforms like LANDR. You can master two tracks a month for free. Listen to some results.
Before and after LANDR
When you upload a track at LANDR, you can tweak several things like loudness options and other settings. The mastering process is fully automated. After your track was processed, you can download the mastered track. In my opinion, LANDR is doing a great job. But it does not substitute a mixing engineer, who makes the track better by brining new styles and elements into the track.
