A modern parser and player for C64 SID files using the Web Audio API.
This SID-Player is a modern reimplementation of the classic Sidplayer by Craig Chamberlain in TypeScript. It uses the Web Audio API to reproduce the sound of the C64 SID chip. Like the original player it displays the played notes in real-time on a virtual piano keyboard. A number of songs can be selected from a drop down menu. Additionally files can be selected from the local drive (e.g. downloaded from Compute's Gazette Sid Collection).
- Supports all features of the original Sidplayer
- Implementation of core SID chip functionalities
- Pure TypeScript implementation without external dependencies
A live version of the player is available here: https://stevi84.github.io/sidplayer/
The player uses the Web Audio API for audio processing. The following diagram shows the structure of the audio network:
- Advanced Sidplayer features not yet implemented
- Waveforms were intendedly not exactly copied from the C64
