Yes they did. But due to the difficulties etc, personally, I am looking at other options. Here are a few that I will evaluate.

- ARTA
- Spectra Plus.
- Virtins Multi Instrument.
- Picoscope 6
- Clio Pocket
- HOLMImpulse
- Digilent Waveforms

All of these do the same or more. I can't wait for Audio Analyzer Suite to maybe pop up again. Anyway, good luck to them who are looking at working things out

Somewhere between my discovering this and ordering the analogy Discovery 2, this software disappeared. Been watching and looking around, starting to feel like something happened to this guy... What a shame

Default Spectrum now suppported in scripts

The latest version of wafeform 2015 now support the use of the spectrum analyser trough the use of scripts.
there is an example of it's usage on the Digilent forum.
Using script with Spectrum on AD2 - Scopes & Instruments - Digilent Forum
I tried it and it works, I am trying to convert the thd value from dbc to %, the math functions are probably there, i just can,t figure this javascript.
I can convert the values in a speadsheet but it is not convenient.

for those like me who do not have access to a working copy of the audio analyser suite, this is a step in the right direction.
You have to adjusts wavegen levels and monitor the output prior to lunching the script.

I supppose there are other also working on this script, so don't despair, a working solution is cooking and should be served soon!

Yup, progress all around! The Analog Discovery is rapidly shaping up to be the ultimate all-in-one beginner's audio analysis tool.

I have used ARTA in demo mode for some time now to do spectrum analyzer measurements of distortion. Demo mode is free...you can save results with screen shots, but can't save data (e.g. numerical values) in demo mode.

Default THD vs Freq script

Hi, for those interested, I posted a new version of the script I am working on.
Using script with Spectrum on AD2 - Scopes & Instruments - Digilent Forum
It is not too complicated to use, set the wavegen voltage to obtain the desired output from your amp under test prior to lunching the script.
also note that if your frequency responce is below 100kHz, the values for high frequencies are invalid. You need at least five harmonics to compute a valid thd figure.
The script is slow compared to the video I have seen of the audio analyser suite, but it is better than nothing for those like me who do not have a working copy.

Could someone send me a copy of this program to me? PM me for email!

Only copy I could find is a non-functional one with no instructions on install.

Nobody in this thread accepts PMs it seems like because people keep asking for it. If anyone can get a copy to me I will host it on my website in my signature for life at no fee.
