Bands 1-3: Peaking filters
- & Peaking EQ filters boost or low a center frequency that you select,
- as well as the frequencies within a certain distance of that
- center. Graphic equalizers in home stereos are usually peaking
- filters. The peaking EQs on Rockbox's parametric equalizer let
- you adjust three different parameters for each EQ band 1
- through 3. The ``center'' parameter controls the center
- frequency that is adjusted by that EQ band. The ``gain''
- parameter controls how much each band is adjusted. Positive
- numbers make the EQ band louder, while negative numbers make
- that EQ band quieter. Finally, the ``Q'' parameter controls how wide
- or narrow each EQ band is. Higher Q values will affect a
- narrow band of frequencies, while lower EQ values will affect
- a wider band of frequencies. \\
