Generate sound effects for your game in realtime.
## Example
```rust
// Create a simple blip sound
let mut sample = usfx::Sample::default();
sample.volume(0.5);
// Use a sine wave oscillator at 500 hz
sample.osc_type(usfx::OscillatorType::Sine);
sample.osc_frequency(500);
// Set the envelope
sample.env_attack(0.02);
sample.env_decay(0.05);
sample.env_sustain(0.2);
sample.env_release(0.5);
// Add some distortion
sample.dis_crunch(0.5);
sample.dis_drive(0.9);
// Create a mixer so we can play the sound
let mut mixer = usfx::Mixer::default();
// Play our sample
mixer.play(sample);
// Plug our mixer into the audio device loop
// ...
mixer.generate(&mut audio_device_buffer);
```
The [`cpal`](examples/cpal.rs) & [`sdl`](examples/sdl2.rs) examples illustrate how to use it with different audio libraries. The [`music`](examples/music.rs) example shows how to create procedurally generated music with it (don't expect a masterpiece though, it's obvious I'm not a musician).
### CPAL Example
To build the [`cpal`](examples/cpal.rs) & [`music`](examples/music.rs) examples on Linux you will need to have the alsa development libraries:
```bash
sudo apt install libasound2-dev
```
### SDL Example
To build the [`sdl`](examples/sdl2.rs) you will need the SDL2 development libraries, on Linux:
```bash
sudo apt install libsdl2-dev
```
