Graphic equalizers like this one in Studio Ultimate are similar in concept to the treble and bass “tone” controls on audio equipment, but provides a much finer degree of adjustment. Studio’s equalizer divides the audio spectrum into ten bands, each centered on a different sound frequency.
Note: In musical terms, each equalization band covers one octave, and the center frequency is close in pitch to the note B.
The sliders let you increase or decrease the contribution of each band’s frequencies to the total sound over a range of 48 dB (-24 to +24). The adjustment to a band is applied full strength at the center frequency, and tapers to zero in either direction.
The display above the slider shows the activity across the audio spectrum as your project is played back.
