Gave a try taking the measurements, not sure if there good or bad (or more importantly, did I do the correctly)???

Hi Celts88,

Your measurements look very well done to me. The impulses are clean. Nothing to say. Congratulations on the measurements !
I noticed that you had only 8 measurements and not 9. Did you not make the sweet-spot ?
As far as presentation is concerned, it is probably easier for Thierry to manipulate one file with the 16 measurements labelled L1..L8 and R1..R8 inside it. Just open a new file, import (open) each measurement and rename it.

A few thoughts on your room if you allow me:

• you look to have a slightly elevated RT60 (reverberation). You might want to think about putting an acoustic ceiling or some sound absorbent

• in some places, you look to have reflections which can affect the sound you listen to:

  To capture this information, you need to look at the Energy Time Curve (ETC). You would not be happy to have reflections above -15db. On the right channel, you have one at -10db and 5ms, which means that the additional distance run by the sound is 5 x 0.340 = 1.7m compared to the direct sound. This might be the wall behind the speaker or a wall on the right of the speaker or the ceiling. You might want to put some absorbent there.
  
• Finally, you have probably noticed some loud resonance in the very low end of the spectrum. [img][/img]
  If this is a nuisance, and instead of installing ugly bass-traps, you can discuss with Thierry the possibility to put a brick-wall filter to not produce sounds below say 20Hz. Up to you.
  

Hope this helps.
