Help RT60 Decay

[AlexK1967]

Sorry
it`s good ?

Difficult to tell from that image, you need to use the "Calculate RT60 model" button in the graph controls to produce the trace that shows the RT60 values, it is then more easily viewed on the RT60 graph (it is the T60M trace).

i`m sorry,

Looks good in the region above 300 Hz where the RT60 results are meaningful.

Thank you very much for your answer, I thought I didn't have a good reverb in my square room

There are issues at low frequencies, but RT60 isn't the right way to look at those. You will see more from looking at the waterfall plot or simply looking at the unsmoothed frequency response.

 

[AlexK1967]

yes, there are problems in the lower frequency of the bass, I think they are introduced by the phase inverter speakers have a range of 44-20000 Hz

Pretty typical of room resonances, you may be able to even things out a little by altering the listening and/or speaker positions. One way to look at that is to play the full range Pink Periodic Noise test signal and watch the response on the RTA while you move things.

thank you, I'll try it
