suited to ones preference. Beware that the crossfeed function is capable of making the
audio distort if you choose settings which result in a too high output level.

Rockbox features a parametric equalizer (EQ). In contrast to non-parametric equalizers,
a parametric EQ enables adjusting the center frequency, gain, and width of EQ bands
separately. The ability to adjust the frequency and width of bands enables more precise
control of the EQ frequency response while avoiding the use of a large number of bands
(often 12+) needed in a non-parametric EQ.
The graphic below illustrates how the width of 10kHz band can be adjusted to cover
a wider (lower Q) or narrower (higher Q) range of frequencies.
In some ways the EQ is similar to the

settings described earlier, but
the EQ allows you to control the sound much more carefully. Note that the parameteric
