Chapter 8. General Settings

Scale.
Select whether the peak meter displays linear or logarithmic values. The
human ear perceives loudness on a logarithmic scale. If the Scale setting is
set to
Logarithmic
(dB) scale, the volume values are scaled logarithmically.
The volume meters of digital audio devices usually are scaled this way. On
the other hand, if you are interested in the power level that is applied to
your headphones you should choose
Linear
display.
This setting cannot
be displayed in units like volts or watts because such units depend on your
headphones.
Minimum and maximum range.
These two options define the full value range
that the peak meter displays. Recommended values for the
Logarithmic
(dB) setting are -40 dB for minimum and 0 dB for maximum. Recommended
values for
Linear
display are 0 and 100%. Note that -40 dB is approxi-
mately 1% in linear value, but if you change the minimum setting in linear
mode slightly and then change to the dB scale, there will be a large change.
You can use these values for ‘zooming’ into the peak meter.
Default Codepage.
A codepage describes the way extended characters that are not
available within the ASCII character set are encoded. ID3v1 tags do not have a
codepage encoding contained so Rockbox needs to know what encoding has been
used when generating these tags. This should be “ISO-8859-1” but to support lan-
guages outside Western Europe most applications use the setting of your operating
system instead. If your operating system uses a different codepage and you are
getting garbled extended characters you should adjust this settings. In most cases
sticking to “ISO-8859-1” would be sufficient.
8.5. System
8.5.1. Battery
Options relating to the battery in the player.
Battery Capacity.
This setting can be used to tell Rockbox what capacity (in mAh) the
battery being used has. The default is 2000 mAh, which is the capacity value for
the standard battery shipped with the player. Rockbox uses this value for runtime
estimation, not battery percentage calculation. Changing this setting has no effect
whatsoever on actual battery life. This setting only affects the accuracy of the
runtime estimation as shown on screen.
8.5.2. Disk
Options relating to the hard disk.
Disk Spindown.
Rockbox has a timer that makes it spin down the hard disk after it is
idle for a certain amount of time. This setting controls the amount of time between
the last user activity and the time that the disk spins down. This idle time is only
