Equalizers Flashcards
What is the fundamental?
lowest frequency in a sound (defines pitch)
What are harmonics?
frequencies that are an integer multiple of the fundamental
What are overtones?
frequencies that are not necessarily an integer multiple of the fundamental
What are formants?
frequencies caused by physical resonances that do not alter in relation to pitch being produced
What is the range of the subsonic band of frequencies?
0-20Hz
What is the main characteristic of sub-bass frequencies?
felt and not heard
What is the range of low bass frequencies?
20-60Hz
What is the main characteristic of low bass frequencies?
associated with power more than pitch
What is the range of mid bass frequencies?
60-120Hz
What is the main characteristic of mid bass frequencies?
start to perceive tonality
What is the range of upper bass frequencies?
120-250Hz
What is the main characteristic of upper bass frequencies?
most instruments have their lowest fundamentals here
What is the range of low-mids?
250-2000Hz
What are the main characteristics of low-mids?
meat, color, timbre (also mud at bottom)
What is the range of high-mids?
2000-6000Hz
What are the main characteristics of high-mids?
loudness, presence, definition, speech intelligibility
What is the range of highs?
6000-20,000Hz
What are the main characteristics of highs?
brilliance, sparkle, air
Where is sibilance found in the frequency spectrum?
2-10kHz
What is a filter?
circuit that acts with reference to single frequency
What is EQ?
device that may consist of a few filters
What is a band?
specific range of frequencies
What shape are parametric filters?
bell curve
What does graphic EQ do?
consists of adjacent mini-faders, each controlling gain of narrow bell shaped band
