Samplerate-rs

A samplerate conversion library for Rust.

This is a fork of the samplerate crate the uses the pure C2Rust transpiled version of libsamplerate in place of the bindings to the C library. This allows compilation without needing to have CMake installed.

Example

```rust extern crate samplerate; extern crate hound;

use samplerate_rs::{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());

} ```
