"Dominator of Resonances pt1"
Basic understanding
Resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration
The term "resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, acoustic resonance can occur at frequencies outside the range of human hearing.
An acoustically resonant object usually has more than one resonance frequency, especially at harmonics of the strongest resonance. It will easily vibrate at those frequencies, and vibrate less strongly at other frequencies. It will "pick out" its resonance frequency from a complex excitation, such as an impulse or a wideband noise excitation. In effect, it is filtering out all frequencies other than its resonance.
Acoustic resonance is an important consideration for instrument builders, as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute
How do resonances sound?
The resonances are very important in many instruments.
Yes, they might sound ugly and painful when listening in solo, maybe remove it completely and it's sound fine. But when listen in full mix, the instrument might lost their timbre and sound very thin or sound just disappear like a magic.
These resonance eat a lot of headroom, the fun thing is that, annoying as resonances can be once you find them, they are really hard to find from scratch.
It is important to understand the difference between attenuating the resonances and extinguishing them completely, in many cases these resonances play an important role in the tone or timbre so they only have to be balanced at the level of the rest of the spectrum.
Sometimes doing a little wide boost in the opposite direction helps increase transparency and reduce the side effects of the cut. As always, the objective is to reduce the outstanding noises which will allow the rest to be heard better, that is, transparency.
*Translate from my analog notebook.
This is not a mixing trick, but essential part of understanding.
No picture atm sorry.
