Thank you for your understanding.
1, why I need to import our code to audio.c
I think, It's for Alex. If we add clear code in audio.c, he is only need to manage single files. Also we can get Alex's code tweak.
2, why I got frustration
Now I'm main worker for 600D audio. But the repo is not mine , scrax's work is really good and provided a good platform to us at that time. But now, he can't understand all of codes when he marge our codes.(too much codes are confusing to him)
The codes are back to old one . and deleted duplicate functions are revival.
So I think, we need to move my repo. I'm almost finished porting audioki.c to my repo.
Then, If you write a production code ,you fork my repo. and make a pull request to me.
And, tragic-lantern will going for your debugging.
It's my concern. How about it?
P.S. Now my code is , agc on/off, controlled from menu . and HighPass filter bug is solved.
