AY_FLY Library

[Guva]

I managed to build the library using cmake.
But I was never able to test it.

It's working!!!   

fwiw: I abandoned this particular project because it depends on sdlaudio and which is besides my use case (I want to play the decoded frames myself and choose which audio backend to use)

Binding to sdl is only needed for an example from the author of the library as a backend, the library itself does not need sdl.

you can use this to avoid dragging the entire raylib https://github.com/raysan5/raudio

It's working!!!   

Confirmed (e.g. works with raudio for me as well)   

Thank you very much guva for that automake wizardry (automake really isn't my virtue).

I am assuming that the changes in the source-code are yours as well ? If so, would you be ok if I put those changes into a patch that can run over the original repository sources and put everything into a bash script like I did for the other projects ? (probably takes me a few days though as I have other things to attend to first).

no, I did not change the source code, I took it from here https://github.com/TTK-qmmp/qmmp-ayfly/tree/master/libayfly

Splendid.

Thank you very much for that hint Guva.

fwiw, I have enhanced the CMakeFiles.txt so that the original source-code does not require any patching.

Attached the libayfly/raudio project with big thank you to Guva for the automake part.

Oh, shit! Very cool script, good job. 

Could you write for raudio as well?
So that I don't have to use the whole raylib.

You meant like the attachment in this post Guva ?

BTW: I am not that familiar with the different YM chips (and the emulation) but libayfly does not seem to support a digital channel.

I didn't quite understand what you mean by Digital Sound? If you're talking about Fm synthesis, then it shouldn't be.
It emulates the AY-3-8910, AY-3-8912 and YM2149 chips. It's just a three-channel sound generator.

I meant digital audio samples 

If you're talking about Fm synthesis, then it shouldn't be.

As said, I am not that familiar with these chips but to my knowledge there are ym chips that do support rendering digital samples. Feel free to correct me though.

He can't play digital samples because there is no fm synthesis.
yes, there are chips that can do this, for example
Yamaha YMF278, YMF262 (OPL3), YM3812, etc

Ah, got it. Thank you very much for the educational lesson there

FM synthesis can be completely done in software as many VST plugins prove. It is actually quite easy to do:
Given X number of pure sine waves let them modulate each other. Where in the case of Yamaha emulation it is likely 5 or 7. What you end up with are raw buffers and those can be played, even in real time (below 5ms latency) on old machines and with quite high sample rates..(96000 or higher)
There's lots of freeware FM VST's around since the early 2000's.
The Stanford/Yamaha patents expired in 1995.
