Measuring room acoustics

Hello there!

It's been a while since I was active but here I am again with new question. I was working on my room in summer and finally finished it so it's "usable". Here're my threads:

Acoustic treatment of a small mixing/tracking room & Ceiling treatment in low ceiling rooms

I'll post some photos of my room later.

So my question is, how to find out whether my room has good acoustics. I mean there are few softwares to measure this but I don't know where to start. I am on mac. Any recommendations?
I don't want a dead room and I really want to have nice and usable early reflections. Here's the only picture I've got so far for my website but I'll take few more so you can see more details.



First reflection panels are 12cm thick and 50kg/m3 dense. Those on the ceiling are 6cm thick and also 50kg/m3 dense. Corner traps are triangle (40x40x56) based and are 5kPa*s/m2 dense.

So basically what I am asking for is an advice on how to measure the quality of my room's acoustics and how to treat them according to my needs.

Thanks!
