### Overview

Port of reSID, a MOS6581 SID emulator engine, to Rust.

### Story

This project originated from zinc64, a Commodore 64 emulator, around Jan 2017.

It evolved to the point where it can be useful to others working on C64 sound/emulation

so it is packaged and shipped as a standalone crate.

### Usage

Once SID register read/writes are wired up to resid, all that is left to do

is to generate audio samples and push them to audio output buffer.

    while delta > 0 {

        let (samples, next_delta) = self.resid.sample(delta, &mut buffer[..], 1);

        let mut output = self.sound_buffer.lock().unwrap();

        for i in 0..samples {

            output.write(buffer[i]);

        }

        delta = next_delta;

    }

| ExternalFilter    | Done        |

| Filter            | Done        |

| Sampler           | Done        |

| Spline            | Done        |

### Changelog

- 0.3 - compliance with the original resid

- 0.4 - full sampler support 

- 0.5 - closed performance gap largely due to resampling 

- 0.6 - SIMD optimization 

- 0.7 - continuous integration and GPLv3 

- 0.8 - documentation and api refinements/internal cleanup

- 0.9 - migration to Rust 2018

- 1.0 - no_std support

- 1.1 - more idiomatic implementation, removes interior mutability and improves support for async rust
