simple as that? So the program averages all the measurements it takes during the set "duration" automatically?

Based on your description, I would recommend that you look in the Octave Analyzer options menu and set Level Type to Leq, turn on Auto Stop, and set the duration to 20 seconds.

Well, I'd like to be able to take RTA measurements, moving the mic around the listening position where the listeners head would be situated during the 20 second interval, and have the RTA average the measurements taken during the 20 second interval.

(I hope that makes sense!)

Can it do that? if so, how do I do that?

Many thanks for your indulgence!

What would you like to do with averaging?

Hi,
Thank you for your response.
I found that, but I can't seem to find anything pertaining to how to use the averaging function.

Do you happen to have instructions you could give me?

Thank you in advance!

In SignalScope, you'll see an info button (a little 'i' in a circle) on the right side of the toolbar at the top of the screen. Tap that, and then tap on Help.

Hi,

The Octave analyzer tool (RTA) supports both exponential (Lp) and linear (Leq) averaging of the signal in each whole or 1/3-octave frequency band. For exponential averaging, Fast, Slow, and Impulse time weightings are supported. For linear averaging, the average level is calculated over the entire duration of the measurement.

SignalScope's built-in documentation includes information on how to access the averaging options.

Let us know if you have more questions.

SignalScope / RTA Averaging

Hi all,

I am wanting to confirm that the RTA program does indeed perform measurement averaging?

am I correct that when running the RTA program, the softwar averages the response measurements made during and controlled  the "duration" time that is specified in the submenu?

As there is no user manual that I have found, I am hoping to confirm this, and also if possible know the proper method/instructions for making use of this functionality please.

Many thanks in advance!

I also requested a multiple-driver option for Speaker Draft app shortly after purchasing it, however, I found a simple way around the problem, which I believe gives accurate results. 

1. Select a preset driver from the list or insert TS values for a new one you intend to use.   

2. Estimate the dimensions for the cabinet you want and Calculate volume and reflex port dimensions for just one driver.

3. Double the volume of the enclosure, and this should be suitable for two identical drivers and two identical reflex tubes. 

If my design does not work out well or sound as it should I will post again to say so.
