## Usage

Add to your `Cargo.toml`:

```toml
[dependencies]
oximedia-effects = "0.1.8"
```

```rust
use oximedia_effects::{AudioEffect, reverb::Freeverb, ReverbConfig};

let config = ReverbConfig::default()
    .with_room_size(0.8)
    .with_damping(0.5)
    .with_wet(0.3);

let mut reverb = Freeverb::new(config, 48000.0);

let mut left = vec![0.0; 1024];
let mut right = vec![0.0; 1024];
reverb.process_stereo(&mut left, &mut right);
```
