SignalScope / Re: RTA Averaging

Yes. With those settings, you'll get the average sound level over 20 seconds in each whole or 1/3 octave band, plus an overall (full bandwidth) average level. You can see the overall level by tapping the graph to turn on the cursor.

Hi Faber, when I tap the graph nothing happens. Is this a bug?

SoundMeter / Re: Calibrate MicW i437L
« Last post by FaberAST on November 27, 2017, 04:50:01 PM »
Unfortunately, the i437L presents itself as if it were a standard headset jack. This means that apps like SoundMeter cannot automatically distinguish between an i437L and a standard headset jack.

Your approach is correct (i.e. Device Units = FS, Channel Units = Pa, Gain = Mid). We do not know the precise input gain used by MicW when testing the sensitivity of the i437L, but using the Mid gain setting in SoundMeter seems to work well.

It's too bad MicW didn't take advantage of the opportunity to produce a digital microphone that presented itself uniquely to iOS. That would have allowed automatic loading of sensitivity information, similar to what SignalScope does with the Digiducer digital accelerometers.

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.
