Amiga Sound Program.

Hello all,

Been a little while since I've been here.

Ok.What I'm looking for is one or both of 2 things.

1. some good reference on the amiga sid chip as in where I need to poke to do this and that on the sid chip (for example, how would I control the ADSR envelop, how I would manipulate and use the LFOs etc.  Here, html, txt, pdf, .GUIDE all good as long as the info is there.

2. Some source code that does this (pretty much regardless of programming language, basically samples I can work with to put into my own project.

Or atleast something to put me on the right track :-).

P.S.: If it helps, I'm using Amiga OS 3.1.  

Thank you all :-).

Amiga doesn't have a  SID chip, C64 does. No ADSR, no LFOs in Amiga (unless if you program them with software).

Amiga sound chip is Paula (MOS Technology 8364). You can find full programming information from the Amiga Hardware Reference Manual (can be found from the Amiga Developer CD for example).

Anyway, poking the hw directly is rather crude thing to do, esp when a lot of people have upgraded their amigas with nice sound cards. You might want consider using AHI.

Hi Piru,

Thanks for the very fast reply.  You'll have to excuse me, I didn't mean to be crude to the amiga :-).  But I come from an amiga era that was before the existence of AHI atleast I'm pretty sure of it....again I might be wrong but I never heard of it in the past.

I'm definitaly going to learn this.  I tried to go to your AHI link listed above but it seems I can't get to the site or something.  

Is there anywhere else I can learn about AHI and how things work?

it finally worked now yes. :-).

toward the end they link to 3 files on the german aminet server....not sure about you, but me, I couldn't get to any of them.  if you can get them, could you email them to me?  or put them on a server so I can get them that way?

3 files?!  It is supposed to link to a description of a large archive of source codes and documentation in LHa format.  Do you have LHa first of all?  If not download it from here.  It comes in a self-extracting archive which contains not only the LHa program but directions on how to use it as well.

Also try that AHI link above again since it should have a link to download the AHI archive.  Make sure your web browser's MIME types are set to recognize a .lha file as an archive that should be downloaded directly to the hard drive.

Post back here if you still have problems.
