There is no way to expect for commercial quality sound from EDM music at professional online audio mixing mastering services if the music producer hasn't made all his best to get as much "perfect" sound as possible at music production stage. No doubts the best is when engineer who is engaged in mixingmakes final decisions on audio processing. Yet there are procedures which are the best to get executed by producer at arrangement stage. Thus producer assures oneself the actions he takes are proper and he delivers to professional mixing and mastering services the edit which is the closest to desired final sound.
1.Filter up Bottom end
Since EDM genre mixing is exceptionally demanding to sound clarity and transparency, there is strong recommendation to cut sub lows at most elements of the music track except Kick and Bass. Beyond dispute it's absolutely right! But it's really important not to carry out this procedure mindlessly otherwise you can harm the audio quality easily. There is a trick broadly used by engineers. In the first instance they build song's foundation by setting the Kick's and Bass' balance up. And only afterwards they add midrangy instruments and sounds - starting from ones which have lower fundamental tone and so on as fundamental tone increases. Say, we have bass, Kick drum, piano progression with broad tessitura, synth pad and saw waveform based lead. Let's get the mixing started. We're adding to perfectly working foundation the next element - most likely it will be Piano since it's register incorporates quite low sounds. Now it's time to clean up bottom end. Apply and rise High Pass filter until your hear piano sound gets thin and wimpy. If engineer did his job on preparing edm track to mixing and mastering services right Piano's lows loss won't get audible thanks to Bass. It compensates the loss with own bottom harmonics. Say, saw Lead will be the next. Most likely it will have to be filtered out at online music mixing and mastering services even more intensively by cause of already three low sounding elements. Working altogether they give plethora of low and mid harmonics.
