rFXGen

A simple and easy-to-use fx sounds generator, based on the amazing Dr.Petter's sfxr.

rFXGen can be used for free as a WebAssembly online tool and it can also be downloaded as a standalone tool for Windows and Linux with some extra features. Binaries for other OSs are not released but they can be compiled from sources.

rFXGen Features

  • Predefined sound presets (Coin, Shoot, Explosion, PowerUp...)
  • Multiple wave types supported (Square, Sawtooth, Sine, Noise)
  • Up to 5 sound slots to store generated sound (temporary save)
  • Load .rfx files with sound generation parameters
  • Save .rfx files with sound generation parameters (104 bytes only)
  • Export wave data as .wav, .raw data or .h code file (byte array)
  • Configurable sample-rate, bits-per-sample and channels on export
  • Multiple GUI styles with support for custom ones (.rgs)
  • Completely free and open-source

rFXGen Standalone Additional Features

  • Command-line support for .rfx to .wav batch conversion
  • Command-line audio player for .wav, .ogg, .mp3 and .flac
  • Completely portable (single-file, no-dependencies)

rFXGen Usage

Open the tools and use the buttons to generate random sounds. Use the sliders to customize sound parameters. Sounds could be saved as .rfx (sound generation parameters) and also exported to .wav, .raw (samples data) and .h (byte array code file).

rFXGen Standalone comes with command-line support for batch conversion and audio playing. For usage help:

rfxgen.exe --help

wow, this tool is super cool (and I love your GUI style too). I tried it out and it made some pretty cool sound effects for my game. Thanks for making this, I found it very helpful :)

Thanks! Glad you like it! 😄

sonar.prochijack!g47 threat notification with Norton AV-- removed my exe several times

That’s a false positive but in case of doubt you can check the source code. rFXGen is open source.

one of the best fx tools i've used! thank you so much for making this :D

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

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.

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.

Save Sound and Export Wave don't work!

Why?

 I use rfxgen_v2.5_win_x64.

It's on my list for review!

Thanks!

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

Thanks for reporting. Please, could you open an issue on rfxgen github project for review?

these sound like the sounds from fighties!

Is there a way to scale this app by a factor 2 or 3? Using it on a high-dpi screen makes everything unreadable for me because everything is tiny.

on the desktop version, there is a Screen Scale x2 button

Linux version lauch this:

./rfxgen: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./rfxgen)

rFXGen was compiled for a newer libc version...

Thanks Ray

It freezes on Arch Linux after the last update lol....

I'll try to recompile it next week...

It should be ok now. :)

Can any sounds generated be exported?

(+1)

yes, you should be able to export generated sounds as .wav just pressing the Export button. Did you try it?

Great tool!

Thank you! Enjoy it! :D

I'd be happy to pay few bucks for Linux version :)

Uploaded! ;)

Thank you <3 I love the dark theme :)

(+3)

Can you make this available for Linux?

(2 edits)

Hi! Sorry, don't have a Linux system right now but you can compile it yourself from source.

Required dependencies are minimum: raylib, raygui, tinyfiledialogs.

If I can compile it myself at some point, I'll upload it.

Can you provide a Makefile or something? Because I get errors trying to compile them from source
