Doesn't Work in Unity about libpyin

[xstreck1]

I've just tested on 2020.3.7f1 and it works (see below), so no idea what exactly your issue is. I'd recommend looking for the specific error you get: https://www.google.com/search?q=unity+DllNotFoundException .

Not out of the box, you have to compile the library for each platform separately. I built the DLL/so back then since I was using it on Windows and Ubuntu. It's a quick process but you need the appropriate tools:

Hmmm, I don't know why it's not working on my end then. Thanks for your reply
Just to make sure, all I need to do in the other classes (in your case, TestLibrary) is call LoadLibrary().use right?
And nothing else? Or is there anything that I should do other than that?

Edit :

I'm fairly new to Unity & C#, but I just wanna ask. Is it because I'm using unity on MacOS?
After searching for a while, I got that one of the cause that might lead to DLL not found is due to some dependencies.

Oh, the DLL is native (it's a C code), so it will not work on Mac (or Linux). This project was published before .NET was even ported to Mac so it did not really make sense to specify.

If you want to run on Mac you'll have to build your own library from the source code. I can't do it since I don't even have a Mac...

Ahh I see, that makes sense now. Thanks for your answer!
I have another question, let say I'm developing this on Windows, am I still able to build the project for mobile devices (Android & iOS)?

Thanks

Okay, I get it, thanks!
I do have another question, so I've tried this library in Windows and it works really well with the simple example that you've provided.

However, I'm having a problem when trying to feed the data with audio files such as mp3. I'm not sure what kind of data that I need to provide for the pyin_feed methods. I've tried to feed the GetSpectrumData & GetOutputData from the AudioSource to the methods but still failed.
