thanks for the zipped files, I downloaded and installed them in a directory.
I tried to run the files, with the new dll, the program will start on winX and Win7, but no run button appears.
no joy with older dll.
Anyone has an idea if it is missing a dependency or something similar?

Could the button be outside the window? I vaguely recall some issues due to font scaling. If your Windows is at 125% or higher, see if changing to 100% helps. If I am remembering correctly, the answer may be in this thread or elsewhere on the forum.

Thank for the advise Bitseeker.
Changing the view to 125% on my win7 laptop force the layout to change and the run button appears.
No luck with my winX desktop .
Settings and help menu do not work, not sure if there is important functionnality not accessible.
I made some loopback measurements on my laptop so I guess it will be fine with an amplifier.
I suppose the only way to preserve measurement is to take screenshots, there does not seem to be a save data of some sort.

at least the most important aspect of the software appears to work fine.

Thank you Azer for the files. I do not yet have my AD but it is on Order. Thank you for confirming functionality micro_freak. So glad I got the files

and now do better audio measurements.

Hi sarel.wagner, unfortunately, it is not fully functionnal.
This afternoon, I tried to make some measurements on one of my old amp, and the display does not scale well on some screens.
Worse than that is that some do not work. especially the frequency responce, I double checked with my scope in parallel.
I did not try the input impedence, output impedence and spectrum analyser.

It's the version he posted in Dec 2015 so there are likely some bugs that were fixes since then.
I know there were some fixes for win10, image scaling and the updated waveforms software.
We would need to wait for somebody that installed a later version to upload theirs.

What was the file called again?

I found something on my NAS called AudioAnalyzerV1.9.exe, could that be it? I might have the sw installed still but haven't used the stationary PC for a few months.

EDIT: I have an installation of ImpedanceAnalyzer file version 1.0.0.507 and AudioAnalyzerSuite file version 1.0.148.334 but crashing with fatal error since I don't have the AD connected.
Can upload the files if they're of any use. (Just verified, the version uploaded in an earlier post was 1.0.358.107 - so my files are older)

abzza · « **Reply #132 on:** August 14, 2017, 10:06:30 am »

@Neganur - yes please, please upload! Just bought my AD2 and this would be seriously handy.

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.
https://forum.digilentinc.com/topic/4383-using-script-with-spectrum-on-ad2/?page=0#comment-17254
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!

Thanks for the update, micro_freak.

Curious, has there been any online chatter or conjecture as to why jaxbird has pulled the pin on both the Audio and impedance analyzers

bitseeker · « **Reply #136 on:** September 11, 2017, 06:58:09 pm »

I haven't heard anything about what happened to jaxbird and his software. It's still a mystery.

micro_freak · « **Reply #137 on:** September 13, 2017, 09:07:09 pm »

Hi, for those interested, I posted a new version of the script I am working on.
https://forum.digilentinc.com/topic/4383-using-script-with-spectrum-on-ad2/?page=0#comment-17254Using 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.

In hope that it is usuful for other too!

bitseeker · « **Reply #138 on:** September 13, 2017, 09:21:01 pm »

That script has undergone quite some enhancement. Nice job.

arahmed · « **Reply #139 on:** April 01, 2018, 08:41:11 pm »

The website www.thestuffmade.com isn't working anymore. Does anyone know where I can download a copy?

Thanks in advance.

Some people do not like music and say all sound systems sound the same are deaf to high frequency audio harmonics, noise and distortion and cannot "carry" a tune.
Most old people without hearing aids and younger people who were exposed to loud sounds are deaf to high audio frequencies.

Tripath made some "class-T" audio ICs then they went bankrupt in about 2007. Their remains were bought by Cirrus Logic but I do not know if they made the class-T ICs. I think a Chinese company owns them now but their products might not match the originals.

Good news:

Audio Analyzer Suite 1.0.0.75 Available for Download

bitseeker · « **Reply #142 on:** November 21, 2018, 05:22:19 pm »

Welcome to the forum, kimahansen. That's great news. Glad to see he was able to find a place to upload new versions.

Note: It's not necessary to watch the video as it's pretty much just a placeholder. The download link is in the video's description.

Subscribe to his YT channel, TheStuffMade, as it appears that's where he's going to announce new releases now.

Can you post the URL for the download link?

Details here:

I am currently working on a new version that will allow using windows sound cards together with the analog discovery.

I think you are the best.

I hope there's a program for sound cards.

Thank you very much. Sir~~
