OS: Arch 64 bit When I run rfxgen empty black window appears. Tested on following versions:

• c132ff build from source with raylib built from master (61e0e4 commit)
• Itch.io builds (both dark and light theme

I tested both options with Intel graphics as well as primusun (Nvidia GPU)

Windows build works via Wine. I tried to run few Raylib examples, they work fine.

cli output:

Screenshot:

This bug is 100% reproducible, follow these steps:

1. Open rfxgen.exe
2. Increase Min frequency value greater or equal to 0.30
3. Decrease Delta Slide value below 0
4. CRASH!

I tried doing the same thing with the GUI version of rfxgen, but it was not working either.

On Windows 10, when using the version downloaded from itch.io .

When I unplug the headphones, the OS automatically selects my screen speakers as the audio output device. RFXGen is still working, but not a sound will play.

If I try to close the application then, it will freeze, forcing me to kill it from the Task Manager.

On Windows 10, when using the version downloaded from itch.io .

I've been saving a lot of files, but when I wanted to load none of them was there :-( .

Splitting the WaveParams-specific API to its own RFXGEN_IMPLEMENTATION rfxgen.h header allows other raylib applications to integrate with its API to generate new wave sounds on the fly.

Once again not the biggest deal, and fixed by hiding task bar or dragging the title bar upwards. But it would be nice if it all fit on screen without doing that.

Following this answer here I compiled the source on my mac, but it gives the follow error

What I actually ran

clang -framework CoreVideo -framework IOKit -framework Cocoa -framework GLUT -framework OpenGL /usr/local/Cellar/raylib/3.5.0/lib/libraylib.a -std=c99 -I/opt/raylib/src -I../../raygui/src/ rfxgen.c external/tinyfiledialogs.c -o rfxgen

Make the code a bit more readable by having RFXGEN_GEN_SAMPLE_SIZE and RFXGEN_GEN_CHANNELS constants. Magic numbers are ambiguous and can cause confusion.

laser.zip

This was the first .sfs file I tried and it doesn't seem compatible.

I don't mind no compatibility but just reporting it as the readme says it is.

Are more features planned for this? Shortcuts for save slots and changing between the waveforms to make them faster to use would be great. Otherwise maybe undo option?
