Overview

The video explains what an equalizer (EQ) does and demonstrates how EQ controls affect a spoken voice. The presenter uses his own voice, an SM57 microphone, and software EQ.

Main Concepts

• EQ shapes tone by changing frequency levels. It makes selected parts of a sound louder or quieter, changing the sound’s character.
• Graphic EQ (GEQ) uses fixed frequency bands, usually adjusted with sliders. The pattern of raised and lowered bands shapes the tone.
• Parametric EQ gives more control over each adjustment:
  • Frequency: Where the adjustment is centered
  • Q or bandwidth: How wide or narrow the affected range is
  • Gain: How much that range is boosted or reduced
• High-pass filter (HPF or low-cut) reduces frequencies below a chosen point. It can remove unnecessary low-end energy, but setting it too high can make a voice sound thin.
• Low-pass filter (LPF) reduces high frequencies. In a mix, gently reducing highs on some sounds can help them avoid competing with a lead voice or other prominent sound.
• Shelving EQ raises or lowers a broad range of frequencies above or below a chosen point rather than focusing on a narrow band.

Vocal EQ Observations

The demonstrations show that an EQ adjustment’s effect depends on the voice, microphone, and settings.

• Low and low-mid frequencies add weight or body. Too much can make a voice boomy; too little can make it thin.
• Midrange changes can affect how full, close, or distant a voice sounds.
• The presenter highlights the roughly 1–5 kHz region as particularly sensitive to listeners. Reducing it too much can make speech less clear, while boosting it too much can sound harsh.
• Higher frequencies contribute to brightness and sibilance. Too much emphasis can make “s” sounds and other sharp consonants unpleasant. Useful frequency points vary by voice and recording.

Finding and Correcting an Unpleasant Frequency

1. Listen for a specific problem, such as a harsh, nasal, boomy, or ringing quality.
2. Use a narrow Q and temporarily boost a band while sweeping its center frequency to find where the problem becomes most obvious.
3. Once you identify the offending frequency, reduce it rather than leaving the boost in place.
4. Adjust the Q and amount of reduction so the correction addresses the problem without making the voice sound unnatural.
5. Compare the result with the original and use the smallest adjustment that solves the issue.

Cautions and Practical Advice

• Use EQ sparingly. Repeated or excessive processing can alter sound quality.
• Prefer cutting problem frequencies over making large boosts. Boosts can increase energy at those frequencies and use up headroom.
• Making a speaker sound flat is not automatically the right goal. The presenter advises against aggressively equalizing speakers to force a particular frequency response; listen to the system and make restrained adjustments.
• A brighter or more heavily processed sound is not necessarily better. EQ decisions should support clarity and balance rather than simply make every sound more prominent.

Speakers and Sources
