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>

Examples

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.)

Simple SID playback

playSID('URL', subtune);

A bit more expert way

If you want to create a SIDplayer object manually before using its functions:

SIDplayer = new jsSID(buffersize, background_noise); //background noise around 0.0005 is suitable

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: go

SIDplayer.loadstart('URL', subtune);

Load

SIDplayer.loadinit('URL', subtune);

Controls

In JavaScript:

SIDplayer.start(subtune);

SIDplayer.playcont();

SIDplayer.pause();

SIDplayer.stop();

In JavaScript:

SIDplayer.setvolume(volume);

SIDplayer.getoutput(); //volume range: 0..1

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
