Equalizer - Toshiba Gigabeat F Manual

Chapter 6. Sound Settings
High-Frequency Attenuation. How much the upper frequencies of the cross path audio
will be dampened. Note that the total level of the higher frequencies will be a
combination of both this setting and the Cross Gain setting.
High-Frequency Cutoff. Decides at which frequency the cross path audio will start to
be cut by the amount described by the High-Frequency Attenuation setting.
Most users will find the default settings to yield satisfactory results, but for the more
adventurous user the settings can be fine-tuned to provide a virtual speaker placement
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.

6.9. Equalizer

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.
