RustDCT
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
// 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.
