# `rFXGen`

A simple and easy-to-use fx sounds generator, based on the amazing [Dr.Petter's sfxr](http://www.drpetter.se/project_sfxr.html).

`rFXGen` can be used for free as a [WebAssembly online tool](https://raylibtech.itch.io/rfxgen) 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.

## 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`)

 - 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)**

 - **Free and open-source**

## 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
