What masking sounds like
Frequency masking happens when two sounds compete in the same range and make each other harder to hear. Two basslines can blur the low end. Two vocal ranges can feel harsh. Two bright hi-hat patterns can make the top end brittle. The meters may look safe while the mix still feels crowded.
Your EQ goal is not always to make both tracks equal. Often, one track should lead and the other should support.
Advanced EQ questions
- Which track owns the sub and kick?
- Which track owns the vocal or main melody?
- Is the incoming track adding energy or just adding noise?
- Can a shorter overlap sound more professional than a long blend?
Common mistakes
- Cutting too much low end and making the room feel thin.
- Boosting EQ to solve a balance problem that gain should fix.
- Leaving two songs full-range because the blend sounds exciting in headphones.
Put It Into Practice
Assignment
Record the same transition four times: no EQ, bass swap only, low plus mid control, and short overlap. Compare which version has the clearest kick, vocal, and emotional impact.
