![minimum rustc 1.37](https://img.shields.io/badge/rustc-1.37+-red.svg)

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.

## Releases

Release notes are available in [RELEASES.md](RELEASES.md).
