High Mids Magic Frequencies
2-4kHz. Can mask the important speech recognition sounds if boosted, introducing a lisping quality into a voice and making sounds formed with the lips such as m, b, and v indistinguishable. Too much boost in this range, especially at 3kHz, can also cause listening fatigue. Dipping the 3kHz range on instrument backgrounds and slightly peaking 3kHz on vocals can make the vocals audible without having to decrease the instrumental level in mixes where the voice would otherwise seem buried.
Description: Contains speech recognition sounds like m, b and v.
Effect: Too much causes listener fatigue.
