Hello, Until today I didn't know there was a new version. Today I tested it on the same 2019 MacBook Pro and the error no longer occurs. It is currently installed with Mac Os Monterey. I'll try the other macs I have but I think it will work. Thank you.

Hi all, Compliments the author, This is a rare and valuable piece of software! Just a question: is there a way to change text color or brightness in scales? Thanks sadikkola surely not a Linux guru...

Hi Walter, Thank you for the explanation. That is helpful.

Hi Tim, You are welcome. I am happy that you like AudMeS. Right, the Y scale is not obvious or plain wrong like V/div, The signal you see is +-1.0 full scale since I switched to floating point. When you select 32768 you have full scale of the A/D converter. I cannot say what that is in volts, because it depends on your sound card and its settings. When you select 16348 you get a zoom factor 2, with 8192 a factor 4 and so on. I am working on a fix to make the Y scale clearer.
-
Hello, This is a nice simple program; thank you for making it available. I do have some questions though. Regarding the X and Y scales on the oscilloscope tab: The X scale is understandable. [us/div] obviously means microseconds per division. And this makes sense in my attached screenshot, where X Scale = 1000 and one division is 1m. (1000 microseconds = 1 millisecond.) But I don't get the Y scale. If Res(olution) [V/div] = 8, then what am I looking at here? The displayed signal goes between -0.2...

Hi Michael I installed OpenSUSE Tumbleweed as VM on my machine. I installed: sudo zypper install cmake-full sudo zypper install -t pattern devel_C_C++ sudo zypper install wxWidgets-3_2-devel sudo zypper install alsa-devel sudo zypper install libpulse-devel and in the project: git clone https://github.com/ben-strasser/fast-cpp-csv-parser libfccp After installing all the dependencies, the code compiles and runs fine. wxWidgets has support for localization. https://docs.wxwidgets.org/3.0/overview_i18n.html....

Hi Juan I got Big Sur running on my Mac. AudMeS works fine on it. I cannot reproduce your issue. Are you using an USB audio adapter? Regards Walter
-
Hi, Can be you need to install the Behringer U-Phono right driver from the maker Behringer? I have two interfaces u-phoria model from this manufacturer and them does not works properly on Windows without install its drivers... No matter on Macs, there no need specific driver to work. Regards.
-
Hi, I checked the Windows app version on same machine with VMWare and it woks like a charm. That confirms it must be a system conflict with Big Sur, because the hardware is the same for both, client and host. Of course all privileges and permissions can be necessary at Mac Os host was activated in system preferences, with no positive results at the mac part: access to internal microphone, full access to internal disk and accessibility, input monitor, etc. I expect you reach any solution because this...

Hi Walter, I think you are right, but it's not a problem of the hardware itself but the app itself for any reason. I have 3 more macs with Big Sur and Catalina (1 iMac 2011, 1 Macbook pro 2011 an 1 Macbook pro 2012) and with all of them the app do its job. I think the mac os version isn't the problem. How can I do what you purposing me? Regards.

Hi Walter, I got it. thank you, Karl

Seems the sound card is not properly detected. I only have a mac book pro with Catalina, not Big Sur, sorry. You could try compiling and debugging on your mac...

Hi Karl, the x-axis is depending sample rate. If the rate i 44100Hz, the time in between each sample is 22,68us and at 10 samples/div the time of the graph is 100 samples which equals 2,27ms.
-
Hi Alan, yes, the accuracy improves with more samples. It also depends on the sample rate you are using; e.g.44100Hz/65536 = 0,67Hz.

Hello there, with the oszilloskope I can see wonderfull sinus waves, but i do not know how to measure the frequnency or wave length. The x-axis is signed with samples/div. How much time is a sample?
-
I use the app for sine generator purposes from long time ago. With the mac model of the tittle with Big Sur installed the app does not do the job. When I open it there says: "Sound card issue: Please check Tools -> Audio interface Configuration" There I see no frequency range eligible, and no input selectable too. On system permissions Audmes has full access to the internal Microphone. Any idea how can a solve this problem?

Alan Cashin posted a comment on discussion Open Discussion
I have answered my own question. The accuracy improves the more FFT samples. Using the maximum samples (65536) the reported frequency is good. Usually within 0.2Hz, which is close enough for me.
-
I downloaded AUDio MEasurement System as I created a Top Octave Generator program for an Atmega328P running at 16MHz. The Atmega328P is required to produce 12 simultaneous square waves with frequencies between 3520Hz and 6645Hz. I had no way of testing if the program was producing anything. The System did the job, proved that it was producing the desired output. The reported frequencies were close (within 10Hz) but not exact. I don't think this is a problem, if the System reports frequencies that...

[Diego Lira] What incredible software! But for those who don't use Debian or derivatives, it is very difficult to build. You use very specific libraries and this makes it very difficult to create packages for other distributions. What do you mean? Are the other distributions missing the needed libraries, or do they uprovide the wrong version, or what? Which distribution are you using, and why not use it on Debian if it is a lot easier? Can you please also provide it in Appimage? This way it is easy...

This way it is easy to use in any distro, flatpak is not very friendly to everyone. Thank you for your attention. Best Regards.
