 +[Placeholder for Frequency Groups discussion]
  
-===== EQ Library =====+**Vocal Descriptions**
  
-Library for praise team and speakers+  * **Rumble / Thumps** Low-end noise from mic handling, stage footsteps, or hard "P" pops (plosives). Usually __below 80Hz__. (Best fixed by turning on the High-Pass Filter / HPF). 
 +  * **Boomy / Muddy** Too much low-end thickness, often caused by the speaker or singer holding the mic too close to their mouth (proximity effect). Around __100Hz-250Hz__. 
 +  * **Warmth** The good part of the low-end that gives a voice body and weight so it doesn't sound thin. Around __200Hz-300Hz__. 
 +  * **Boxy** Too much frequency buildup making it sound like the person is talking inside a small cardboard box. Around __400Hz-600Hz__. 
 +  * **Honky / Nasal** Sounds like the person is speaking through their nose, cupping the microphone capsule, or talking over a telephone. Around __800Hz-1.5kHz__. 
 +  * **Harsh / Aggressive** Piercing or painful high-mid frequencies that fatigue the ears. Around __2.5kHz-4kHz__. 
 +  * **Presence / Clarity** The sweet spot that helps the congregation clearly understand the actual words being spoken or sung. Around __4kHz-6kHz__. (If vocals are buried under the instruments, a slight boost here helps). 
 +  * **Sibilant ("Esses")** Sharp, painful hissing sounds on consonants like "S", "T", "C", or "Ch". Usually around __5kHz-8kHz__. (Can be fixed with an EQ cut or by using a De-Esser). 
 +  * **Air / Sparkle** The very top end that gives a vocal an open, breathy, and natural feel. Around __10kHz-16kHz__.
