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

rFXGen can be used for free as an 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.

• Predefined sound presets (Coin, Shoot, Explosion, PowerUp...)
• Multiple wave types supported (Square, Sawtooth, Sine, Noise)
• Up to 4 save slots to store generated sound (temporary save)
• Load .rfx sounds or import .sfs files (compatible with sfxr)
• Save .rfx sounds with generation parameters (104 bytes only)
• Export generated waves with configurable sample-rate and bits-per-sample
• Export to .wav, .raw data or .h code file (byte array)
• Five unique GUI styles: Light, Jungle, Candy, Lavanda and Cyber

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

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:
