GB sound emulation w/pascal

[phedon]

Hi,
I'm currently working on a tool (written in pascal), therefor I need to know how this works.
I have absolutly zero knowledge of sound programming (but I know how to code ).
Does anyone have informations for me about where to begin?
Gameboy emulation is declared as rather easy here at emutalk :satisfied

Regards

phedon

edit
For now it's enough to output some tones/notes/sounds/instruments - no full music
For example:
Instrument data:
Type: Pulse
Envelope: 77
Wave: 50%
Length: FF
Sweep: FF
Hope this is helpful

hi,
first of all welcome to the forum.
And well firstly i assume you know how to playback samples in pascal and then you can have a look at this paper:

This sheet is very complete, the sound emulation of my gb i solely based on it.
If you have more specific questions how to exactly emulate it, feel free to post it here

edit:
woops sorry i didnt see your edit, gonna change my post accordingly later on when i got time
