How To Fix Muddy Vocals

Vocal EQ is a subject most engineers have struggled with.

Since the vocal sound is such an important part of the mix, no wonder it keeps you up at night.

You want just the perfect sounding EQ curve. Thickness and clarity without muddiness.

So here are 5 steps for dealing with muddiness when you're mixing your next vocal track.

1. Filtering

Sometimes you don't need to surgically cut out the lower mids to clear up the muddiness in the vocals. Sometimes you just need to get a little heavy-handed on the high-pass filter.

2. Nasal Sound

If there's one pet peeve I have with vocals, it's the nasally sound caused by too much 1 kHz. But the weird thing is, you can't always just cut the frequency to get rid of the nasal sound. 

That creates a thin sound that's exactly the opposite of what you want. And if you have too much low-mid buildup in your vocal, it will even harder to get that vocal on the right track, no pun intended.

3. Masking

When that nasally sound happens, masking is a good way to hide a certain sound. By boosting slightly above the frequency that's causing problems you can often hide the sound you're having trouble with.

4. Weight

Being scared of muddiness can also cause other problems. You might be avoiding certain frequency ranges because of their reputation for causing muddiness. But then you might end up with a thin sounding vocal. Don't be scared to boost the vocals in the lower-mids if your singer is sounding a little thin. Sometimes that's exactly what a vocal needs.

5. Presence

If you're not having any problems with muddiness, but the vocal doesn't seem to stand out, boosting the higher mids can sometimes save the sound. Subtractive EQ is great and all, but sometimes you just want to smack some 5 kHz on there.


Too much low-mid build up does cause muddiness in your vocals but it's not always a matter of cutting a frequency and leaving it at that. The frequency spectrum is a complicated web of frequencies that all relate to each other.

Cutting one frequency has relative consequences to all the other ones. If you cut the low-mids, the relative gain of the high-mids is increased so carefully navigating the frequency range to get the best sounding vocal sound is tricky.
