* volume: Add a PA_VOLUME_UI_MAX define for the recommended max volume to show ↵Colin Guthrie2011-03-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | in UIs This value is not a technical upper limit, it's just a 'sensible' value that is not crazy high, but also allows software amplification above 0dB (aka 100%) for very quiet audio sources. We recommend that a comprehensive volume control UI should allow users to set volumes up to this limit, although of course should deal gracefully if the user has set the volume even higher than this without resulting in a feedback loop that effectively limits the upper volume. The value chosen is +11dB. This was selected somewhat subjectively and is very similar to the current 150% that gnome-volume-control uses (which is ~+10.57dB). On the plus side, we now recommend that everyone allows 'Volumes up to 11' which is pretty awesome. http://en.wikipedia.org/wiki/Up_to_eleven https://tango.0pointer.de/pipermail/pulseaudio-discuss/2010-April/006945.html https://tango.0pointer.de/pipermail/pulseaudio-discuss/2010-April/006950.html

* doxygen: Fix version numbers for new featuresColin Guthrie2010-12-041-2/+2
| | | | | | Due to how our branching worked out, these new features will debut in v1.0 and not v0.9.22 which has already been released from the stable-queue branch
* volume: Decrease PA_VOLUME_MAX to be < 2^31Arun Raghavan2010-10-151-1/+1
| | | | | | | This decrease PA_VOLUME_MAX to be less than 2^31. We want to do this in order to simplify signed arithmetic when applying software volume scaling (since the volume can now always be safely treated as a signed number).
* volume: Clamp volume to PA_VOLUME_MAXArun Raghavan2010-10-151-0/+3
| | | | | | This ensures that we always clamp the volume to PA_VOLUME_MAX. While this currently has no effect, it will be required for making sure we don't exceed PA_VOLUME_MAX when its value changes in the future.
* volume: Use a macro to check if a volume is validArun Raghavan2010-10-151-0/+3
| | | | | | | This adds a PA_VOLUME_IS_VALID() macro for checking if a given pa_volume_t is valid. This makes changes to the volume ranges simpler (just change PA_VOLUME_MAX, for example, without needing to modify any other code).
* doxygen: Add 'See also' linking to the overview pageDavid Fries2010-10-131-1/+4
| | | | | | | A good many of the header files are broken into a function reference page and an overview page. These changes add a direct link from each function reference page to their overview page if one exists.
* doxygen: Fix the "all" comments regarding volume helper functions.David Fries2010-10-131-10/+11
| | | | | | Mostly change "Set the volume of all channels" to "Set the volume of the first n channels" as the first is incorrect, it doesn't set all the channels and doesn't explain what n was for.
* headers: Some trivial fixes for some documentation typosMads Kiilerich2010-01-051-3/+3
| | | | | | | | | | | | | | | | Note also the willneed/will_need inconsistency. I guess it could be nice to ASAP choose one of them and introduce a backward compatibility hack for the other. The issues was mostly found with: for a in $(grep -r '^[ /]\*.*()' $( find -name '*.[ch]') | sed 's,^.* \([^ ]*\)().*$,\1,g' | sort | uniq | grep ^pa_) do grep -rq "^.[^*].*\<$a(" $(find * -name '*.h') || echo $a done
