Audio masking threshold estimation lib headers, docs and examples

Evaluates the simultaneous masking threshold for audio. The masking threshold is a psychoacoustics property of the perception of sound. This threshold determines the cut-off in perception. Any Fourier signal below the threshold is not perceived by listeners.

Simultaneous masking is the basis of mp3 audio compression. This GPL implementation allows arbitrary sample rate and window sizes. It is extremely simple to use, rather cheap in computation complexity and gives great results. To alter the degree of masking (quality of the playback after compression), simply shift the threshold this library generates up and down.

The development files are found in the documentation directory under /usr/share/doc. It includes a good API, as well as examples. The examples include C++ and an octave file to view the result.
