UNDERSTAND EQ
HERE IS A VERY HELPFUL OVERVIEW OF FREQUENCIES
Although these definitions were clearly compiled for rock music, with a little bit of abstraction they can be applied to any sound used – even in the electronic realm.
The “low end” is the weakness of many home studio mixes, and the same applies here: if you can’t hear exactly what you’re doing, you should avoid extreme settings.
Popular: dull bass drums, completely filtered out bass, exaggerated “crisp” hihats and cymbals.
Not only does this usually mean that it doesn’t sound good, but you can no longer cut it on vinyl.
It’s best to print them out and hang them up in the studio – have fun!
BASSDRUM
- “Mud frequencies” can be lowered at 300Hz.
- Try a small boost at 5-7kHz for presence.
- 50-100Hz – defines the depth
- 100-250Hz – makes the sound “round”
- 250-800Hz – “mud” range
- 5-8kHz – Presence
- 8-12kHz – Sibilance
SNARE
- Try boosting at 60-120 Hz if the sound is too weak.
- 6KHz for a crisper sound.
- 100-250Hz – Fullness
- 6-8kHz – Presence
HIHATS AND CYMBALS
- Again: lower the muddiness at 300Hz.
To bring in brilliance, boost a little at 3 kHz. - 250-800Hz – mud range
- 1-6kHz – Presence
- 6-8kHz – Definition
- 8-12kHz – Brilliance
BASS
- Try boosting at 60Hz to define more “body”.
Mud at 300Hz.
If the sound needs to be more present, boost at 6kHz. - 50-100Hz – gives depth
- 100-250Hz – makes the sound rounder
- 250-800Hz – Mud
- 800-1kHz – “meat” on smaller speakers
- 1-6kHz – Presence
- 6-8kHz – treble presence
- 8-12kHz – Sibilance
PIANO
- Who would have thought it, lower the 300Hz 🙂 and raise the 6kHz for definition.
- 50-100Hz – Body
- 100-250Hz – “round”
- 250-1kHz – Mud
- 1-6kHz – Presence
- 6-8Khz – Clarity
- 8-12kHz – “stringiness”
E-GUITARS
- Again, it all depends on the mix and the recording. Either cut or boost the 300Hz range, depending on the song and the guitar sound. “Edge” at 3kHz boost, or transparency by lowering this frequency. Boosting at 6kHz brings presence and boosting at 10kHz brings brilliance.
- 100-250Hz – Body
- 250-800Hz – mud range
- 1-6Khz – comes through well in the mix
- 6-8kHz – Clarity
- 8-12kHz – Sibilance
ACUSTIC GUITAR
- Look for and attenuate muddy frequencies between 100 and 300Hz. Small cuts between 1-3kHz help to shift the sound image further upwards. Boosting at 5kHz leads to greater presence.
- 100-250Hz – Body
- 6-8kHz – Clarity
- 8-12kHz – Brilliance
STREICHER
- Completely dependent on sound and mix.
- 50-100Hz – Depth
- 100-250Hz – Body
- 250-800Hz – mud range
- 1-6hHz – “crunchy”
- 6-8kHz – Clarity
- 8-12kHz – Brilliance
VOCALS
- Difficult, because it depends entirely on the mic used.
Anyway: the usual 300Hz, but either boost or cut depending on the mic and song.
Boost very little at 6kHz to increase clarity. - 100-250Hz – brings the voice forward
- 250-800Hz – Mud
100HZ
- Boost to create a harder bass sound for the lowest-frequency instruments.
- Boost to give guitars and snare more fullness.
(Rock) - Raise to warm up piano and brass sounds.
- Attenuate to make boomy guitars clearer.
200HZ
- Boost to make vocals fuller.
- Boost to make snare and hard guitar sound fuller.
- Lowering to avoid muddiness of vocals or mid-range instruments.
- Lowering to eliminate the “gong sound” of cymbals.
400HZ
- Boost to give the bassline clarity (especially when listening quietly).
- Lowering to minimize the “cardboard sound” of bass drum and toms.
- Lowering to reduce the room sound on overheads and cymbals.
800HZ
- Boost to increase the clarity and “punch” of the bass.
- Lower the volume to avoid a cheap guitar sound.
1.5KHZ
- Boost to emphasize the crispness and clarity of the bass.
- Attenuation to make the guitar sound less muffled.
3KHZ
- Raise to make bass more defined.
- Boost for more “attack” on guitars and low piano parts.
- Boost to make voices clearer/harder.
- Lowering to get an airy, soft sound from background vocals.
- Lowering to conceal out-of-tune guitars/vocals.
5KHZ
- Lifting for vocal presence
- Boost to give bass drums more attack (also toms).
- Raise to bring out plucking noises in the bass.
- Boost to increase the “attack” of piano, acoustic guitar.
- Lower to make the elements in the background appear “further away”.
- Lowering to make quiet guitars softer.
7KHZ
- Boost to give (bass) drums a more metallic sound (NuMetal).
- Boost to give percussion sounds more attack.
- Boost to make muffled vocals clearer.
- Raise to make the double bass more defined.
- The S frequency of the most votes.
- Boost to make synthesizers, rock guitars, acoustic guitars and piano “sharper”.
10KHZ
- Boost to make vocals more brilliant.
- Boost to make acoustic guitar and piano more gently brilliant.
- Raise to make the pelvis “harder”.
- Lowering for an overall less sharp S-sound for vocals
15KHZ
- Boost to make vocals “airier”.
- Raise to make cymbals, strings and flutes more “expensive”.
- Boost to make samples sound more “real”.
AND THIS IS ALSO HELPFUL:
Subbass: everything below 50Hz
Bass drum and bass usually take up the most space in this area.
Sub bass is one of the reasons why maxi singles came on the market: low frequencies need much wider grooves – so you have to cut everything below 50Hz on long albums or 7″ singles.
We recommend NOT boosting in this range unless you have REALLY good studio speakers.
It’s a common mistake that leaves you wondering why the record sounds 10dB quieter than others…
Bass: 50-250Hz
This is where most “bass” controls on stereo systems intervene, although nowadays the bass range is between 90 and 200Hz (with the above-mentioned boosts in the “presence” frequencies.
muddiness/”irritating” range: 200-800Hz
The “most popular” reason for dull and undefined sounding mixes – hence the term “irritating range”.
Most frequencies around this range can lead to psychoacoustic problems: if too many sounds dominate here, the mix quickly becomes annoying, so that you want to finish quickly or boost an exaggerated amount of highs to conceal this, even if the sounds used don’t want to sound like that.
Mid-range (presence): 800-6kHz
The human ear is extremely sensitive in this range, and even a 1dB boost will result in a big change in sound – as if you were to boost 10dB in other ranges!
This is because our voices are located in this area of the frequency spectrum – that’s why you can hear more accurately here than
elsewhere.
Most telephones are loudest around 3kHz because this is where speech intelligibility is greatest.
Work very carefully here, especially with vocals.
Treble: 6-8kHz
This is where the “treble” controls on the average stereo system come into play.
Boosts in this area make the sound artificially more brilliant – one is inclined to say “more real” if one is not careful when mastering.
Highest treble: 8-20kHz
This range is dominated by the high frequencies of cymbals and hihats – but boosting can result in a “more expensive” hi-fi sound.
In any case, only boost very carefully here too – and on good speakers.
The ear tires quickly with too many “high trebles” and you should always have a reference CD to hand.
