Equalisation or equalisation is the process of adjusting the balance between frequency components within an electronic signal. The most well known use of equalisation is in sound recording and reproduction but there are many other applications in electronics and telecommunications.
THREE EQ BANDS
50-60 Hz
- Thump in a kick drum
- Boom in a bassline
- Essential in dub, dubstep and reggae !
- Too much and you’ll have flapping speakers and a flabby mix
- Too little, and the mix will never have enough weight or depth
100-200 Hz
- This EQ band adds punch in a snare
- Gives richness or “bloom” to almost anything
- Too much makes things boomy or woolly
- Too little sounds thin and cold
200-500 Hz
- Crucial for warmth and weight in guitars, piano and vocals
- Too much makes things sound muddy or congested
- Too little makes them thin and weak
500-1000 Hz
- One of the trickiest areas
- Gives body and tone to many instruments
- Too much sounds hollow, nasal or honky
- Too little sounds thin and harsh
2 kHz
- Gives edge and bite to guitars and vocals
- Adds aggression and clarity
- Too much is painful!
- Too little will sound soft or muted
5-10 kHz
- Adds clarity, open-ness and life
- Important for the top end of drums, especially snare
- Too much sounds gritty or scratchy
- Too little will lack presence and energy
16 kHz
- Can add air, space or sparkle
- Almost too high to hear
- Too much will sound artificial, hyped or fizzy
- Too little will sound dull and stifled
