In a modern audio production world, when professional music mixing at adequately high quality degree has become easily achievable with no need to leave own bedroom, one thing the very fundamental in this process has shifted to rear plan being shaded with hype on techniques and super innovative tools. It's arrangement and recording! Let's face - nowadays it's fairly trivial to put the blame for sort of "wrong" sound and music insufficient fascination on audio mixing and mastering services studio. Instead of paying attention to what was happening long time before this process. Namely - to the idea that was put to music, arrangement quality and recording of course. After all it's much easier to put all responsibility on engineer or tight budget, obstructing to hire top-tier pro, instead of admit that production itself wasn't made at proper level. For better understanding let's draw a parallel - online mixing and mastering is alike to our clothing. And arrangement in that case is our body. Now then if we visiting fridge more often than a gym and got surplus 8-10kg, eminent brands clothing is powerless to fix it anyhow. The same is studio engineer can't fix faint production. Please don't take me wrong - this process is also very important and has huge influence at final audio quality. But mixing is far not primary in music opposite to material preparation quality. The proper one even just being put to a DAW already has to expose song's potential and make the listeners wave their heads. Even with just proper balance set. Mixing and mastering engineer's task is just to clean up, to shape this jewel and to show it's strong points. Yet far not to create something it was missing originally. That's what everyone trying to put the blame for own flaws on other's shoulders have to realize. And that's exactly the way to create a piece of art that one day might be considered an "evergreen" - a song that never gets old or uninteresting to audience. But long story short now we're getting right to the point of our talk and will survey in detail all flaws that are awaiting for inexperienced producer. The flaws that will most likely prevent him of getting that desirable "commercial" varnished quality sound at the output.
