# Samplerate

[![Build Status](https://travis-ci.org/Prior99/rust-samplerate.svg?branch=master)](https://travis-ci.org/Prior99/rust-samplerate)

[![Docs](https://docs.rs/samplerate/badge.svg)](https://docs.rs/samplerate/)

A samplerate conversion library for Rust.

This library provides a high-level API for [libsamplerate-sys](https://github.com/Prior99/libsamplerate-sys) and hence is built on top of [libsamplerate](http://www.mega-nerd.com/SRC/api.html).

# Example

```rust

extern crate samplerate;

extern crate hound;

use samplerate::{convert, ConverterType};

use hound::{WavSpec, WavWriter, SampleFormat};

fn main() {

    // Generate a 880Hz sine wave for 1 second in 44100Hz with one channel.

    let freq = std::f32::consts::PI * 880f32 / 44100f32;

    let input: Vec = (0..44100 * 5).map(|i| (freq * i as f32).sin()).collect();

    // Resample the input from 44100Hz to 48000Hz.

    let resampled = convert(44100, 48000, 1, ConverterType::SincBestQuality, &input).unwrap();

    // Write the resampled pcm data to disk.

    let mut writer = WavWriter::create("resampled.wav", WavSpec {

        channels: 1,

        sample_rate: 48000,

        bits_per_sample: 32,

        sample_format: SampleFormat::Float,

    }).unwrap();

    resampled.iter().for_each(|i| writer.write_sample(*i).unwrap());

}

```
