A very lightweight (14kbyte, samplecycle-based) and fast SID emulator written entirely in pure JavaScript (from scratch) for the Web Audio API, supported by most major web-browsers. No need for Flash/Java or other plugins to play SID files directly in the browser by the visitors of the webpage...

Features
- Very small (14kbyte) coded from scratch in pure JS
- Very lightweight on CPU (running in 44kHz sample-periods not at 1MHz)
- High pitched and thin sounds are cleaned from aliasing (band-limited)
- ADSR delay-bug/wraparound emulation for crisp/modern short soundstarts required in most music
- 6581 and 8580 models selectable on the fly (cutoff-curve/combined-waveform)
- Combined waveforms generated algorithmically (workings reverse engineered from SID-schematic)
- Background-noise can be added if wished
- Cycle-based CPU emulation despite 44kHz samplecycle operation
- Some illegal opcodes (LAX,SAX) are supported by CPU part
- Easy-to-use interfaces and callbacks for e.g. auto-advance in playlist
- 2nd and 3rd SID support - playing 2SID and 3SID tunes (since v0.9.1)
