Handy EQ tips for filtering lows, taming muddiness and bringing out the mids

Published: Thu, 09/15/16

You'll like this handy EQ tip method I came up with the other day.

I used it on an electric keyboard track but the theory can be used for numerous tracks.

The goal is to filter out the lows, tame the muddiness and boxiness while adding slight masking via boosting to bring out some of the mids to make the instrument cut through.

Step 1 - Filter

If it's not a bass instrument you're perfectly fine with filtering everything out below 100 Hz.

If you hear your mix clean up with more drastic filtering while you play this track in context with the rest of the mix then keep going on the filter.

Just make sure it's not really thin in case it's a crucial part of the mix somewhere and you've accidentally taken all the weight out.

Step 2 - Shelving Cut

On instruments where low-mids aren't the most important because...

  • a) There are already enough low frequency instruments
  • b) This track has problem with causing muddiness in the low-mids

...I like using a shelving cut instead of a bell cut.

It basically acts as a less aggressive filter.

Instead of taking all the frequencies out with the filter I'm reducing the energy from the filter cut-off frequency to the shelving cut frequency.

In this case the piano was getting in the way of the bass guitar and distorted electric guitars in the 2-400 Hz area. This made everything sit a bit better but I still needed to give the keyboard its spot in the mix.

Step 3 - Masking Boost

I find keyboards sounding very nice when I boost them in the 500-700 Hz range. It's a mid-frequency range that seems to go  unused but can work wonders to bring out certain instruments in the mix.

Also try hunting around that area for:

  • Roundness in the snare
  • Harmonics in the bass guitar
  • Character frequency for electric guitars (midway between "weight" and "attack")

I just used a high Q on the shelving EQ to create a boost at the end of the shelving cut but you can easily use a separate bell boost if you need to go hunting any higher.

Results

This accomplishes three things:

  1. Cleanup in the low region
  2. A controlled lower-mid range that doesn't clutter up the rest of the mix
  3. A place for the instrument to cut through

You can also do this using a low-pass filter in case you have a full-range instrument that needs some cleanup in the highs and high-mids.

Say an crunchy electric guitar that sounds a bit hissy. Then you just filter out the highs, add a bit of shelving to tame the very high-mids and add a boost to make them cut through.

Try this tip out the next you want a simple EQ approach that gives you very effective results.
