Dynamic Range Compression with Limiting and Expansion

Dear friends!

After a lot of TImewasting i askting for ur support.

My Topic is the Dynamic Range Compression. i try to setup a Gain Computer inwhich a Expander, Compressor and a Limiter Included. Therfore i tryed to combine them but failed. The biggest Isues i have is in setting up a Rule where and when which object should be used to Calculate the Gain. I searched a lot but couldn t finde a good solution in which way i can set up an Algorithem who does this. Notice that i dont want to use a Straight Forward system.

Any Help or Links where i can find some Starting points where and how i can Setup this Algorithm would be Great.

hello

not sure, but are you trying to put something like a and mu law companders (compression / expanders) in a script / simulation ?

Hey there,

kinda, i want to amplifie an audio signal and reduce the Low Amplitutes by using the expander or a noisegate. Higher Amplitutes should then be compresst so the strength of the amplifie will be reduced. And after the amplified Signal gets to Loud i want to Limit it to a threshold. All these Modifications should then be combined in an Gain Computer who selects how to React on the Input signal and then apply the Gain to it. It SHould be Like this:

hello

it seems that it already exist :
