Step 1: remove rumbleUse a high pass filter (aka low cut filter). Increase the cut-off frequency until you just start to hear the difference, then reduce it a bit. That's right, aim for not hearing the effect. This ensures that you only remove rubbish, and don't remove valuable data. A typical cut-off frequency will be around 80Hz-120Hz.
When done, check the effect in the mix.
Step 2: give glitter
Step 3: sweep sound
Step 4: special fxThis step is optional.
- To make sound brighter, try to boost 2kHz-5kHz.
- To make vocal sit better in the mix in quieter passages, try cutting between 100Hz-250Hz
