Hi all
I've searched for AGC Code along the forum. I found nothing. Finaly I found something on google groups, that has to be ported to SM Code.
I've no plan how to port that thing, cause I'm defenetly no programmer (for no, but still learning).
Can somebody help me out a little bit?
loop forever
{
/* Voltage controlled amplifier is just a multiplier here */
yout=yin*iout
/* error */
err=spoint-abs(yout)
/* Integrate */
iout1=iout
iout=iout1+gain*err
}
I've tried already , without positive result :/

Hi there,
The code there, luckily, can be copied almost directly - I have had to make some educated guesses about what the variables are representing, but I'm pretty sure this is a good translation.
The code will have three inputs - the incoming audio, the target volume level, and a control to set the speed of gain changes. Gain would be between 0 and 1, but I think you'll need pretty small numbers at the "gain" input to get usable times.
streamin yin; //Audio Input
streamin spoint; //Target gain (I think)
streamin gain; //Controls speed of gain changes
For code that is just maths, like that one, the translation is usually fairly simple, you just need to understand those first few lines where "streamin" creates an input connector, "streamout" creates an output connector. Then you must declare a list of variables that you need to use ("float") - so that SM can plan how much memory is needed.
And all code lines in SM must finish with a semi-colon ":".
