Equalisation. Each EQ band influences different qualities of a mix or instrument:
- 50-60 Hz � adds thump in a kick drum and boom in a bassline
- 100-200 Hz � adds punch in a snare and richness
- 200-500 Hz � adds warmth and weight in guitars, piano and vocals
- 500-1000 Hz � adds body and tone to many instruments
- 2 kHz � adds clarity, edge and bite to guitars and vocals
- 5-10 kHz � adds clarity, openness and life, especially drums
- 16 kHz � adds air, space or sparkle
