Crate libsoxr

libsoxr-rs

This library is a thin wrapper for libsoxr which is a "High quality, one-dimensional sample-rate conversion library".

For direct access to the libsoxr functions, you can use the libsoxr-sys crate.

This wrapper library is licensed the same as libsoxr itself: LGPLv2.

The documentation can be found here.

Install

add the following to your Cargo.toml:

[dependencies]
libsoxr = "0.2"

Example

// upscale factor 2, one channel with all the defaults
let soxr = Soxr::create(1.0, 2.0, 1, None, None, None).unwrap();

// source data, taken from 1-single-block.c of libsoxr examples.
let source: [f32; 48] = [0.0, 1.0, 0.0, -1.0, 0.0, 1.0, 0.0, -1.0, 0.0, 1.0, 0.0, -1.0, 0.0,
                         1.0, 0.0, -1.0, 0.0, 1.0, 0.0, -1.0, 0.0, 1.0, 0.0, -1.0, 0.0, 1.0,
                         0.0, -1.0, 0.0, 1.0, 0.0, -1.0, 0.0, 1.0, 0.0, -1.0, 0.0, 1.0, 0.0,
                         -1.0, 0.0, 1.0, 0.0, -1.0, 0.0, 1.0, 0.0, -1.0];

// create room for 2*48 = 96 samples
let mut target: [f32; 96] = [0.0; 96];

// Two runs. First run will convert the source data into target.
// Last run with None is to inform resampler of end-of-input so it can clean up
soxr.process(Some(&source), &mut target).unwrap();
soxr.process::<f32,_>(None, &mut target[0..]).unwrap();

// just print the values in target
for s in target.iter() {
  print!("{:?}\t", s)
}
