is a plugin for the DeadDBeeF music player. This plugin skips quiet passages at the beginning and end of a track. But it can also skip (almost) noiseless areas within a track which is often the case with an attached hidden track.
In the settings of the plug-in you can set which threshold values must be undercut, the values are in dB. Values of -1 deactivate the respective function.
Copy the compiled plugin to the plugin folder (~/.local/lib/deadbeef/) and restart
DeadDBeeF, then it works without further configuration.
