|
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);
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
