[FEATURE] RoomAnalysis class for monaural room impulse response parameters calculation.

[Chum4k3r]

Developed this new class inside rooms.py to provide ways to calculate room parameters like Clarity, Definition, Early Decay Time, Reverberation Time and other.

It inherits from the Analysis class, so it is a class for calculating and viewing the parameters values, but still cannot cross reference impulse responses from different source-room-receiver arrangements, as if means and standard deviations are to be calculated together with the parameters. These still can be done with some looping through IRs and accessing the desired parameter data.

It also drops the need of Numba for JIT compilation of the reverberation time routines.

There is an example file that have a quick demonstration on how to instantiate a RoomParameters object and view its room evaluations.

wow, nice contribution \o/ I needed some time to analyse everything :>

Looks you are cropping the IR twice, I pointed in the code and commented a bit more. My suggestion to solve the problem is to calculate all the energy parameters from the EDC, maybe the energy compensation is something we want for the other parameters as well. Prof @eric-brandao can comment a bit more on this for sure.

About removing Numba dependency: I did some tests here, and for small calculations, it's okay to wait a bit more, but if you are calculating from many impulsive responses to do some sort of averaging and statistical analysis it would get painful. About making the toolbox compatible with ARM devices, is Numba the only thing that makes the toolbox useless on those devices? Is it worth to trade speed which is important to room-acoustics users for some compatibility with those devices?

I've tested with a few different IRs I've found, including some from the last Round Robin and it runs ok. Believe it is now ready for merge.
