While usually this is a good thing (think about a bomb which make you jump on your chair), sometimes you may want or need to be quiet and you don't want to continuously use the volume button on your remote controller.
Mplayer comes with a filter named volnorm (which you find in xt7 under chains window) which tries to raise the volume level without distorting the sound, it is useful but not always effective enough.
In my experience, i found ladspa plugins + mplayer very useful for this job.
You will need:
* ladspa swh plugins
* mplayer compiled with ladspa plugin support (which gives -af ladspa)
* xt7-player >= 0.8.2
Even if xt7-player doesn't wrap ladspa,
you can still use the custom audio filter in chains window:
Under the Custom audio filter configuration,
you will enable a slot and write the ladspa filter parameters:
What i use is:
- Code: Select all
Use the ladspa filter in: /usr/lib/ladspa/fast_lookahead_limiter_1913.so
From that filter, use the plugin: fastLookaheadLimiter
Plugin parameters follows: "10:0:2", the most important is "10" which tells the filter to dinamically boost the sound up to 10db, while not distort the sound.
You can raise this value up to 20db.
