Effects on music
Fundamentals of bass drum, tuba, double bass and organ.
These frequencies give music a sense of power. If over-
emphasized they make the music "muddy". The 50 or 60
Hz band is also used to reject AC mains hum.
Fundamentals of lower tympani. Too much boost produces
excessive "boom". 100 or 125 Hz are also used for hum
rejection.
Drum and lower bass. Too much boost produces
excessive "boom". Also useful for 3rd harmonic mains hum
rejection.
Fundamentals of strings and percussion.
Fundamentals and harmonics of strings, keyboards and
percussion. Boosting the 600 to 1 kHz range can make
instruments sound horn-like.
Drums, guitar, accentuation of vocals, strings and bass.
Too much boost in the 1 to 2 kHz range can make
instuments sound tinny. Too much boost anywhere
between 1 to 4 kHz can produce "listening fatigue".
Accentuation of percussion, cymbals and snare drum.
Reduction at 5 kHz makes overall sound more distant and
transparent. Reduction of tape hiss and system noise. The
1.25 to 8 kHz governs clarity and definition.
Cymbals and overall brightness. Too much boost causes
sibilance. Reduction of tape hiss and system noise.
