A couple of questions here.
1: My understanding of mix and master is the process for the big project including many instruments. I use Alice Key Piano VST to write some simple piano pieces. Is there any mix/master technique that I might be able to apply to the piano solo songs to make them more impressive?
2: Another question is that sometimes, the exported song's volume is low. Because it is a piano piece, I cannot use a compressor to reduce the dynamic range, then enhance all frequency together. So, is there any way to make it louder? If the music hit the end of the peak meter and clipping, is that still good to export (Because it sounds ok after I export a song that was clipping badly in FL-studio)? How should I know the volume is good and proper for the exported songs to be released and heard by a listener, or we just try to make it as loud as possible without clipping?
3: If you turn up/down the volume via the FL studio volume knob on the top right. Will it influence the final exported track's volume. Or, the knob is only used for convenience when you work on a project in FL studio, no matter how you turn the knob, it doesn't impact the exported song's volume?
4: When you work on Fl-studio, is the sound the best quality? I mean, sometimes when I export the wav. the document about 40-50Mb, it seems to sound better than I heard when I was working on it, such as some noise it not that obvious to hear.
