Add the Percentage Articulation Loss of Consonants indicator

See this reference: V. M. A. Peutz. "Articulation Loss of Consonants as a Criteria for Speech Transmission in a Room," Journal of Audio Engineering Society, Dec 1971

This is an outdated room acoustics parameter. The STI (speech transmission index) is used nowadays

I have added basic STI calculation in my fork of I-SIMPA. The results are comparable to ones obtained with CATT-Acoustic. The main issue is that it currently it doesn't compensate for speaker characteristics (female, male etc.). If you are interested I can try to port the code to the main branch.

The main commit is https://github.com/wbinek/I-Simpa/commit/c11273c9d8157fd37cb26f30ea0cd2c024bc220f , but unfortunately some other changes are spreaded across other commits.

Hi,

Great, thanks for the contribution. @Picaut Are you interested in STI ?

Picaut commented 5 years ago

Yes. Of course. Can be merged easily ? Should be tested too.

wbinek commented 5 years ago

Ok, I will port the code and create a pull request in main repository next week.
