Add a "volume limit" parameter to the configuration file. The maximum
value of volume setting in sound menu will be limited to the same as
volume limit. Also each time when setvol() is excuted, Rockbox will
check if the global_settings.volume value larger than
global_settings.volume_limit. If larger, take the value of volume_limit
instead. The volume_limit argument shares the same maximum and minimum values
with volume argument, while taking the maximum volume as its default value.

This is an improvement to the current compressor which I have added
to my own Sansa Fuze V2 build. I am submitting here in case others
find it interesting.
Features added to the existing compressor:
Attack, Look-ahead, Sidechain Filtering.
Exponential attack and release characteristic response.
Benefits from adding missing features:
Attack:
Preserve perceived "brightness" of tone by letting onset transients
come through at a higher level than the rest of the compressed program
material.
Look-ahead:
With Attack comes clipping on the leading several cycles of a transient
onset. With look-ahead function, this can be pre-emptively mitigated with
a slower gain change (less distortion). Look-ahead limiting is implemented
to prevent clipping while keeping gain change ramp to an interval near 3ms
instead of instant attack.
The existing compressor implementation distorts the leading edge of a
transient by causing instant gain change, resulting in log() distortion.
This sounds "woofy" to me.
Exponential Attack/Release:
eMore natural sounding. On attack, this is a true straight line of 10dB per
attack interval. Release is a little different, however, sounds natural as
an analog compressor.
Sidechain Filtering:
Mild high-pass filter reduces response to low frequency onsets. For example,
a hard kick drum is less likely to make the whole of the program material
appear to fade in and out. Combined with a moderate attack time, such a
transient will ride through with minimal audible artifact.
Overall these changes make dynamic music sound more "open", more natural. The
goal of a compressor is to make dyanamic music sound louder without necessarily
sounding as though it has been compressed. I believe these changes come closer to this goal.
Enjoy. If not, I am enjoying it

Missing screenshots:
Invadrox, which I can't find in the menu, but on IRC they said it's
for LCD only, so it should be removed.
Pacbox, Rockboy and Zxbox: it's unclear where to find the ROMs.
Poor quality image:
manual/rockbox_interface/images/sansaclipzip-front.png. It can work,
but my “artistic” skills are not enough. Anyway, the information on
the picture is correct.
All the screenshots were taken using the default theme and the
simulator compiled for the Sansa Clip Zip.

Where before there was a single sleep timer menu option which handled
initiating/ cancelling a sleep timer as well as setting the default duration,
now there is one menu option to either start or cancel a sleep timer and
another to set the default duration that will be used for future sleep timers.

Resume positions stored in bookmarks take precedence over autoresume.
Technically, the resume position for the "Resume Playback" function
(which is also saved across power-off/power-on) also takes precedence
over autoresume. However, there is no way for a user to tell as it is
identical to the autoresume position for the last-played track, so
don't highlight it in the manual.
