--- Quote from: jaxbird on June 03, 2016, 04:33:48 pm ---It would be nice to have a decent 24bit, 192/384ksps sound card cover the 20Hz to 20-40kHz range to get more dynamic range while having the Analog Discovery measure the levels. It would be fairly simple to implement code wise, but it would require some external hardware for input/output switching, attenuation selection etc.

There is an alternative, you can combine the two channels into one with a simple attenuator. Obviously this will drift a lot with temperature, but with online calibration it can work. In fact with online calibration you can create a ultra pure sine with such a makeshift DAC.

See "Low Cost Ultra-Pure Sine Wave Generation with Self Calibration". In short you selectively low pass the DACs, because the low pass only affects the harmonics for the DACs you can detect/correct them even with an ADC which itself is also significantly non-linear. The software is not entirely trivial, but with the ADC/DAC using one clock it will be simpler than in the paper (no need to detect the fundamental).

I just bought a Analog Discovery 2 but now the software is not available anymore!
Could anyone or jaxbird share a copy with me please.
Thanks!
bitseeker:
The Audio Analyzer Suite cannot easily be shared. Why? Because the download was only an installer. It did not include the software. Only after running the installer was the latest version of the software downloaded directly from the site and onto your computer. So, without the site being up, the required installation package is not available even if you had downloaded the .exe file before the site went offline.

Try the attached files, it is the files downloaded by the installer.
I don't think it is the latest version. I don't have the AD here and it complains that it can't be found on startup so I don't know if it runs ok without the server online.
The files are located in a subfolder of c:\users\yourusername\AppData\Local\Apps\2.0\ if anybody has one of the later versions.
bitseeker:
Thanks azer. I don't know if it'll run as-is from the already-installed files. My PC already has all the proper registry entries, folders, etc. created by the installer, so I don't know what it'll do on a clean system. Someone very familiar with the Windows installer may be able to take the next step to make it installable. I see the manifest and config files in your archive, but haven't worked with Windows installers in decades, so I'm unsure if that has all the necessary information.

The processor architecture in my version is different from yours. Interesting. So, the app and/or .Net version that they were built for may be sufficiently different.

Mine:
<assemblyIdentity name="AudioAnalyzerSuite" processorArchitecture="msil" version="1.0.26.374" />

Yours:
<assemblyIdentity name="AudioAnalyzerSuite" processorArchitecture="x86" version="1.0.358.107" />
