Can’t save sounds or export waves on Windows 10. I’m using rfxgen_v2.5_win_x64.

Ray96 days ago

It should work... but I'll review that.

I reviewed rFXGen and I couldn't find any issue. I was able to save/load .rfx files with no problem, as well as export .wav in different wave formats. I tested it on Windows 10. Where did you tried to save the files? Maybe it's a permissions issue.

Orbbloff95 days ago

Thanks for the review! I tried various directories to save the files and I don’t think it’s permission issue. I tried saving on desktop, a folder in desktop, a folder in D: disk. I also tried running the app as administrator but that didn’t help too.

I'm afraid I have no idea why it doesn't work for you. Fortunately, rFXGen is an open-source project, you can try to compile the code yourself and check for the issue with a debugger. A preconfigured Visual Studio 2022 solution as well as a plain Makefile are provided.

.wav export doesn't seem to work. The .wav file generated sounds completely different compared to what's in the editor.
