Problem
Plosive removal weakens low-frequency consonants along with the unwanted microphone bursts.
Solution
Root Cause / Diagnostic:
High-velocity breath blasts on unshielded microphone diaphragms produce high-amplitude plosive thuds ('P' and 'B' bursts) concentrated below 150 Hz. Applying a blunt, static high-pass filter or broad EQ cut across the entire vocal track eliminates the plosive burst, but simultaneously removes natural chest resonance and vocal weight. This leaves male and low-pitched female voices sounding uncomfortably thin and nasal.
Actionable Fix:
1. Apply targeted dynamic EQ or an automated de-plosive plugin (e.g., iZotope RX De-plosive) calibrated strictly to trigger when energy below 100 Hz exceeds a -18 dBFS threshold.
2. Set a static high-pass filter at a conservative 80 Hz with an 18 dB/octave slope to protect fundamental vocal pitch harmonics.
3. Solo the dialogue track and compare vowel and consonant transitions before and after processing to confirm vocal richness remains intact.
Pro Tip:
Angle the microphone capsule 45 degrees off-axis from talent's mouth line rather than pointing it directly at the lips on set; this diverts aerodynamic breath bursts away from the diaphragm entirely.
