How It works
PeppySpectrum leverages fifo/named pipe for receiving volume signal from audio players. The communication over named pipe doesn't need any additional library. That makes PeppySpectrum a simple and slim application. peppyalsa ALSA plugin should be installed to make PeppySpectrum functional. That plugin outputs volume level signal to the named pipe. PeppySpectrum reads that signal from another end of the named pipe.
