RustDCT is a pure-Rust signal processing library that computes the most common Discrete Cosine Transforms: 

 * Discrete Cosine Transform (DCT) Types 1, 2, 3, 4
 * Discrete Sine Transform (DST) Types 1, 2, 3, 4
 * Modified Discrete Cosine Transform (MDCT)

## Example
```rust
// Compute a DCT Type 2 of size 1234
use rustdct::DctPlanner;

let mut planner = DctPlanner::new();
let mut dct = planner.plan_dct2(1234);

let mut buffer = vec![0f32; 1234];

dct.process_dct2(&mut buffer);

```

## Compatibility
The `rustdct` crate requires rustc 1.37 or greater.
