Introduction To Additive Eqing
Additive EQing involves boosting specific frequencies to enhance or shape a sound. Unlike subtractive EQing, which involves cutting frequencies to remove unwanted sounds, additive EQing allows for precise adjustments to bring out desired tones and frequencies.
What Is Additive Eqing?
Additive EQing is one of the most crucial audio mixing techniques. It involves boosting certain frequencies in a track to make them more prominent. This means adding a frequency range to a sound that is not present or not easily heard. Additive EQing can often add depth and warmth to a mix and is commonly used in music production, particularly in genres like hip hop, electronic, and pop.
How It Is Used?
Additive EQing is commonly used when a track has a particular frequency that is lacking. By boosting certain frequency ranges, the sound becomes fuller, and the mix becomes more balanced. For example, if a guitar track doesn’t have much low end, then adding some lower frequencies with the equalizer can give the guitar a fuller sound. When using additive EQ, it’s essential not to overdo it. Too much boosting can make the sound too harsh or muddy. Therefore, it’s critical to keep a balance between adding frequencies and maintaining the integrity of the original sound.
Best Practices
There are some best practices when it comes to using additive EQing. Firstly, it’s essential to make sure that the audio sounds good in its raw form. Eqing should not be used to fix poorly recorded audio. Instead, it should be used to enhance it further. Another best practice is to use a high-pass filter before adding any frequencies. A high-pass filter removes the low-end noise that can affect your mixes negatively. Also, using a narrow Q when boosting frequencies can help improve the accuracy of the boost. Finally, when using additive EQing, it’s crucial to take breaks regularly. The ears can get fatigued when listening to the same frequencies for an extended period, which can affect the quality of your final mix.
