Hi everyone, I start GNU Companion and I m looking for stocking datas. I explain you the situation : I got an audio source and I would like to stock each values which is transmitted into a vector in order to get the max of these values but I don’t know which block can allow it.  
Can you enlighten me?  
Thanks
