Mixing is a complex art, and even experienced producers can fall into common traps. A muddy mix, a disappearing vocal, or a low-end that's either too boomy or non-existent can ruin an otherwise great track.
Here are five of the most common mistakes we see and how you can fix them in your own productions.
1. A Muddy Low-Mid Range
This is the #1 problem in most amateur mixes. The 200-500Hz range is where bass, guitars, synths, and even vocals can clash, creating a "muddy" or "boxy" sound.
The Fix: Be aggressive with your EQs. Use a high-pass filter on everything that doesn't need to live in the low-end (like vocals, hi-hats, and guitars). Then, make surgical "cuts" (narrow Q) in the 200-500Hz range on instruments like bass and rhythm guitars to make space for the kick and vocal.
2. Uncontrolled Low End
The opposite problem is a low-end that's all over the place. This is often caused by a sub-bass (under 60Hz) that's too loud or a kick and bass that are fighting for the same frequency.
The Fix: Use sidechain compression. Sidechain the bass to the kick drum so the bass "ducks" by a few dB every time the kick hits. This creates space and rhythm.
3. Harsh Sibilance
Bright vocals and aggressive EQ can leave esses and ch sounds fatiguing, especially on laptop speakers and earbuds.
The Fix: Ride clip gain or volume automation on problem syllables first, then use a de-esser with a narrow band on the harsh region (often 5–9 kHz). Light multiband compression on the top end can also tame peaks without dulling the whole vocal.
4. Squashed Dynamics
Slamming a single compressor or limiter across the mix bus early in the process can steal life from drums and vocals before the song is even balanced.
The Fix: Mix into gentle bus compression if you like the glue, but save loudness for the mastering stage—or a dedicated limiter pass after the balance feels right. Stage your dynamics: clip gain and fader rides first, then character compression on individual elements.
5. Messy Stereo Field
Wide synths and doubled guitars are fun, but phasey low end or an overcrowded sides image can make a mix collapse in mono or on phones.
The Fix: High-pass or mono-sum bass-heavy sources below ~120 Hz when it helps the groove. Use a correlation meter and mono checks; if something disappears or thins in mono, tighten the stereo width or nudge timing on doubles.
