EQ

Understanding EQ

Equalisation (EQ) is a crucial tool for sound manipulation in recording and production.

  • Purpose: The main purpose of using EQ is to balance the different frequencies in a sound.
  • Components: There are typically referred to as ‘bands’ which represent specific frequency ranges that can be adjusted, e.g. ‘low’, ‘mid’, ‘high’.
  • Types: There are various types of EQs including graphic, parametric, semi-parametric and shelving.

Utilising EQ for Corrective Purposes

EQ serves an essential role in making corrections during the recording and production process.

  • Freqeuncy Imbalances: You can use EQ to fix frequency imbalances to avoid overloaded or ‘muddy’ areas within a recording.
  • Remove Unwanted Frequencies: You can also use EQ to remove unwanted low frequency rumble or high frequency hiss.
  • Avoid Masking: EQ is a central tool in ensuring one instrument or sound does not mask another.

Using EQ for Creative Purposes

In addition to corrective actions, EQ is widely used for creative effect.

  • Shape Character: EQ can shape the character of an instrument, adding warmth or brightness, depth or edge.
  • Vocals Enhancement: With vocals, you can use EQ to improve clarity, body and presence.
  • Add Variety: It can be used to add variety to arrangements by highlighting different frequencies in repeated sections.

Understanding EQ Settings

Getting to grips with various settings in EQ can help shape your sound.

  • Frequency: This setting selects the centre frequency you’ll be affecting.
  • Gain: This setting affects how much you boost or cut the selected frequency.
  • Bandwidth/Q Factor: This setting adjusts the range of frequencies affected around the centre frequency.

EQ in Context

Understanding how to use EQ in context can take your mixing abilities to new heights.

  • Hearsafe: Avoid ‘soloing’ an instrument when EQing. The settings may sound great on their own but can negatively impact the overall mix.
  • Ear Fatigue: Take regular breaks to avoid ear fatigue and to keep a fresh perspective.
  • Subtractive over Additive: Following the principle of ‘subtractive over additive’ EQ can help manage headroom and noise build-up.

Remember, EQ is a powerful and nuanced tool. Be patient and practice regularly to develop your skills and intuition in using it.
