jsSID by Hermit - a javascript SID emulator and player for the Web Audio API
(It doesn't need Flash-player or Java-VM, it's pure JavaScript.)

Web Audio API is supported (and contained) by browsers (according to Wikipedia) since these versions:
Firefox 23, Chrome 10, Opera 15, Safari 6, M$ Edge 12,
Chrome for Android 28, Mobile Safari 6 (restricted), Mobile Firefox 23, Tizen

The player supports simple Vsync/CIA timed SIDs. SIDs with custom player and digis are not fully implemented.
To include jsSID at your page, 'jsSID.js' should be included in body/header of your HTML code:
<script type="text/javascript" src="jsSID.js"> </script>

Let's see some examples (HTML buttons that handle various aspects of jsSID):

Simple way: If you just want to simply play a SID without manually creating and initializing a JS object:
(This creates a jsSID object called 'SIDplayer' automatically behind the scene, so you can use its functions.)

playSID('URL',subtune);

A bit more expert way: If you want to create a SIDplayer object manually before using its functions:
objectname = new jsSID(buffersize, background_noise); //background noise around 0.0005 is suitable
(We use 'SIDplayer' as objectname in this example. Samplerate is inherited from the web-browser, usually 44100Hz.)
(Buffersize values that make sense: 1024/2048/4096/8192/16384, maximal 16384 advised at 44100Hz and above)
Then (as jsSID object called 'SIDplayer' is created) you can use its subfunctions/methods:

Choose file: or type local URL:
SIDplayer.loadstart('URL', subtune);


SIDplayer.loadinit('URL', subtune);

subtune:1
SIDplayer.start(subtune); SIDplayer.playcont(); SIDplayer.pause(); SIDplayer.stop();

volume: 100%
SIDplayer.setvolume(volume); SIDplayer.getoutput(); //volume range: 0..1.0

SID Title: ...
SID Author: ...
SID release info: ...
No. of subtunes: 0 , preferred SID-model for tune: 0, using:
SIDplayer.gettitle(); SIDplayer.getauthor(); SIDplayer.getinfo();
SIDplayer.getsubtunes(); SIDplayer.getprefmodel(); SIDplayer.getplaytime(); //'playtime' is in seconds
SID-model for playback: SIDplayer.getmodel(); SIDplayer.setmodel(model); //models: 8580.0 or 6581.0
Set callback functions (e.g. displaying SID-file info) for jsSID events:
SIDplayer.setloadcallback(function_name); SIDplayer.setstartcallback(fn); SIDplayer.setendcallback(fn,playtime); //in seconds

A simple playlist player can be found in this folder: playlist.html
