How do I master a song with clear and loud sound in FL Studio?
First of all, one should be very clear about mastering the mix. It's not a single virtual knob to deal with. It's a huge concept, require lots of experience. I think, no one till now is the king of mastering, they can't even say themselves, the same.No one can teach you, how to master.It's a self learning process. You'll develop after each and every attempt, examining the sounds with the perfect gear (it's important).Mastering the mix is an art to give the perfect space to each elements, without losing it's significant frequencies, up to the maximum volume(gain) level.In the case of FL studio, inbuilt tools like Maximus (optimize towards the required frequencies), Soundgoodizer (makes sound crispier), Wavecandy (examining the inhead audio distribution & db level) etc. are mostly used.Well, the above mentions uses the basic audio equalization. It's direct and easiest way to do. But, when it comes to channel splitting (mono/ stereo), mechanical arrangements are required, or it can be performed virtually in FL studio. For, this it's mandatory to know about “Mid-side Processing”.What is Mid/Side Processing?In FL studio, Patcher is the ultimate tool to implement Mid-Side Processing.The above arrangements, which allows you to split the optimistized mono & stereo channel passing over Stereo Shaper & then through Fruity Parametric EQ 2, which creates the balanced output.Remember : All these operations are done only in master channel.These are some of the basic theory to do so, but remember again, there is no hard & fast rule for mastering. Everyone is learning by their mistakes. Using tools (vsts/plugins) effectively is also an art. Go! train your ears.
