Equalization (or EQ) refers to the adjustment of audio frequencies produced by drums, which can either be cut or boosted to reduce or increase the presence of a specific frequency or frequency band. This is usually done to improve the audio aesthetics of drum sounds.
EQ may be used to eliminate or reduce unwanted sounds and transients, and altering EQ is a good way to adjust the timbre of the drums by modifying the substance of its frequencies. This can furthermore assist in fitting the drum tracks within the sonic spectrum and overall context of the mix.
Depending on the application, different EQ units can be more suitable than others
i.e. frequency fine tuning, removing bad or error frequencies, boosting highlighting tones
Some popular choices include:
Classic Neve EQs such as 1073 and 1084 and API 560 for fine tuning
API 550 and 560 for tweaking problem frequencies and boosting highlighting tones
We love API 550s on toms, 560s on kick and snare and Neves for room mics and overheads
