Detailed Description

Return only the power spectrum components above the masking threshold.

This code originates from https://feapi.svn.sourceforge.net/svnroot/feapi/trunk/FEAPI/examples/plugin/FEAPIExamplePluginLoudness/FEAPIExamplePluginLoudness.cpp and has been modified. It is based on the psycho-acoustic model in ITU-R BS.1387.

The input is a power spectrum, the output is the difference of the input spectrum and the masking threshold

Controls:

• mrs_real listeningLevelInDbSpl: since the masking depends on the level, this impacts the masking threshold
