JSep is a highly experimental work-in-progress Enterprise-128 emulator written in JavaScript for decent, modern browsers. It's my attempt to create an Enterprise-128 emulator using only web techologies.
The problem: http://stackoverflow.com/questions/24907738/webaudio-with-firefox-onaudioprocess-callback-is-not-called.
URL is
http://ep.lgb.hu/jsep/demo.new/?sound=yes. You must click on the "run"
button to start the emulation. You should hear some keyboard
click feedback especially if you hold a key for longer time. You can also
use the PING IS-BASIC command inside the emulator to create a sound.
The sound quality is known to be awful, and subject of over/underflow of the
audio buffer, but it's a known problem of mine. The real problem:
no audio with firefox, but works with chrome. It seems firefox does not even
call the callback registered with .onaudioprocess. My
only problem now to be able to produce any sound with Firefox
as well, not only Chrome.
Beware, the source of the emulator is a mess. Honestly it's a project for me to learn JavaScript and "modern" web technologies ... It will need a major re-construction soon.
Relevant source files:
enterpriseInitEmulation(), near the end of the function.
audioPlay(), called by clicking on the "run" button,
emulator(), the actual "main" function which re-executes
itself with setTimeout().
processAudioJavaScriptCallBack() at the end of the file, it's
the callback registered with audioNode.onaudioprocess.
