Electroacoustics Toolbox / Spectrogram 3D Surface: missing x/y/z scale
« Last post by audiot1949 on October 31, 2015, 10:46:49 AM »
You can rotate the diagram but the scales are missing.
The shown scales respond to the 2D diagram and not to the 3D.
Please have a look at the screenshot.

Well, they are in the collected measurement data as values. To have it as selectable curves too would be nice!

Electroacoustics Toolbox / Room Tools Analyzer: General
« Last post by audiot1949 on October 31, 2015, 10:45:19 AM »
This is really, really a great and awesome tool!
Like it very much, but you should provide a “cooking recipe” with a block diagram and screen shots how to set it up and get it work.
It took me hours to make the setup and get sensible results because of missing info.
Ben, thank you again, without your detailed help I couldn’t have got it work properly!

Electroacoustics Toolbox / Re: nan dB

"nan" stands for "not a number" and indicates that some invalid arithmetic operation occurred (like dividing zero by zero).

Electroacoustics Toolbox / nan dB
« Last post by brianf7408 on October 16, 2015, 06:41:46 PM »
Occasionally when attempting to take a THD, SNR, etc., I get the characters "nan".  What does that stand for and what can i do about it?

Am I correct in assuming that the number of spectral lines is equivalent to the number of bins?
Yes. Each line represents one bin.

SignalScope Pro / signal generator burst
« Last post by geadinc on August 19, 2015, 11:41:32 AM »
I don't suppose there's an easy way to create a burst of audio i.e. 100% AM modulated, using the signal generator? Trying to measure the response of a compressor.

Cool, thanks! I'll be using a Presonus Firestudio Mobile to give me the XLR in and out.

SignalScope Pro / Re: THD measurement

SignalScope Pro's FFT Analyzer tool is capable of computing THD with up to 15 harmonics.
In order to get good results, you'll need to use a test signal that's at a frequency that matches one of the frequency bins in the FFT. This is fairly simple if you use SignalScope Pro's built-in signal generator and use the same audio device for both output and input in your measurements.
