EQ basics for beginner video editors: cleaner dialogue in minutes
EQ is the fastest way to make dialogue sound professional. Here are the beginner moves that clean up voice without making it sound unnatural.
Equalization, or EQ, is the tool that lets you boost or cut specific frequencies. For video editors, it is mostly used to make dialogue clear and remove problems. You do not need to understand every frequency to use EQ well. A few common moves handle 90% of dialogue issues.
Remove rumble with a high-pass filter
A high-pass filter removes low frequencies below a set point. For dialogue, set it around 80 Hz. This removes handling noise, wind rumble, and traffic without hurting the voice. If the voice is very deep, you might use 60 Hz. Do not go higher than 100 Hz or voices will sound thin.
Cut around 200 Hz to reduce boxiness
Recordings made in small rooms, cars, or with lavalier microphones often build up around 200 Hz. This is the boxy or muddy range. A small, narrow cut of 2 to 4 dB here can clean up the voice quickly. Listen while you adjust and stop as soon as the voice opens up.
Add clarity around 4 kHz to 6 kHz
The presence range lives between 4 kHz and 6 kHz. A gentle boost here makes consonants easier to understand and helps dialogue cut through music. Be careful, too much boost sounds harsh and sibilant. A 1 to 2 dB lift is usually enough.
Control sibilance above 7 kHz
Sibilance is the sharp s and sh sound. If a voice is too bright, a narrow cut around 7 kHz to 10 kHz can help. A de-esser is a specialized EQ tool for this job. For a quick fix, use a parametric EQ with a narrow Q.
Always compare before and after
EQ moves are easy to overdo. Bypass the EQ every few adjustments and listen. If the untreated version sounds better, your settings are too aggressive. The goal is a voice that sounds natural and sits clearly in the mix.
