Equalization (EQ) techniques are important tools that help make your music sound better when you're mixing it. By changing different sound ranges, producers can make their tracks clearer and more balanced.

Key EQ Concepts:

1. Frequency Ranges:

   • Low Frequencies (20 Hz - 250 Hz): These make your sound feel warm and full.
   • Mid Frequencies (250 Hz - 4 kHz): These are key for making sounds clear and easy to understand.
   • High Frequencies (4 kHz - 20 kHz): These add brightness and a light feel to the music.

2. Cutting vs. Boosting:

   • Research shows that cutting (reducing) sounds is often better than boosting (increasing) them for a natural sound. For example, lowering certain sounds by $2 - 6$ dB can help.
   • Boosting can work well too, especially in the $1 - 2$ kHz range for making vocals stand out, but it should be done carefully to keep things clear.

3. Use of EQ in Mixing:

   • About 70% of the decisions you make while mixing involve EQ changes.
   • Good EQ can make your music sound louder by up to 3 dB without actually turning up the volume.

Transformational Benefits:

• Makes the sounds of different instruments clearer and easier to tell apart.
• Stronger vocal sounds can lead to a deeper emotional connection with the listeners.
• Reduces sounds that overlap, helping everything work together nicely in the mix.

By using EQ techniques wisely, you can greatly improve how your music sounds in the end.
