Equalization is basictal for getting your tracks to blend together. I wrote several techniques that you may want to realize about when using equalization in audio mixing
Gauge each and every frequency range in every single track and then make adjustments that builds a continuous and cohesive sound that blends well together.
Avoid cutting and boosting all your tracks at the same frequency range. You need to construct EQ settings that work well together. If each track is boosted and cut at the same frequency range, your song will most likely very harsh and your tracks will be competing for the same frequency ranges.
You need to make strategic cuts and boost on your tracks so instruments in the same frequency range do not mask each other. For illustration the Kick drum and the bass guitar both sit in the low end of the frequency spectrum. If you boost the kick drum at 65kHz, you should not boost your bass guitar at 65kHz. You should actually cut your bass guitar at 65kHz and boost it someplace else, like 250Hz and if you boost your bass guitar at 250Hz, then you need to cut your kick drum at 250Hz. Are you following the trend here? Practicing this technique will improve your mixes drastically. This kind of EQ techniques is called Complimentary EQ’ing.
Linear Phase EQ:
Eqs are made from filters that change the frequency of an audio signal. When an EQ filters frequencies within the range, the signal can be delayed a very small amount. These delays can cause phase issues with the audio signal. A linear phase EQ fixes that issue.
That’s why linear phase Eq’a are smooth and transparent eq’s.
For example: Chorus’s and flanges work with changing the phase and they make beautiful effects. Those effects alter the phase (timing) of the path of an audio signal.
