Problem
Balance background music so consonants and key spoken words remain intelligible on phone speakers.
Solution
Root Cause / Diagnostic:
Background music often contains heavy acoustic energy in the 1 kHz to 4 kHz range—the exact frequency band responsible for human speech intelligibility and consonant definition (T, K, S, P sounds). On compact phone speakers, this frequency overlap turns speech into an unintelligible muddy murmur.
Actionable Step-by-Step Fix:
1. Carve a Parametric EQ Pocket: Apply a 3–4 dB parametric dip in your background music around 1 kHz to 3.5 kHz to carve out space for voiceover clarity.
2. Boost Vocal Formants: Apply a gentle high-shelf boost (1–2 dB above 5 kHz) and a narrow midrange boost around 2.5 kHz to enhance voice clarity.
3. Lower Overall Bed Levels: Keep background music at least 15 to 20 dB below peak voice levels during spoken sections to preserve clear vocal dominance.
Pro Creator Tip:
Phone speakers lack dynamic range and stereo separation; cut the 1 kHz–3 kHz range in your music bed so your words slice through cleanly.
