are where you want to start looking. These examples might be a easier way to start:

although even this page assumes a lot of background on audio engineering. If you search

Google with the query:

"Sound on Sound" "Compression Made Easy"

the top link should be a tutorial in the magazine Sound on Sound on the topic. Good luck,

Hello Gustav1851,

I assume the product you are inquiring about is the ADAU1701?

I designed this AGC circuit to try to keep the output at a target level you set.

This should be a good start for you.
