Hi, I'm new to PD, using it as an elective for college.
How would I go about stopping audio input from dropping back to 0 once it reaches a certain point. ie: If the Audio levels reach +20, It will go no lower than +20, as it reaches +30 it will go no lower than +30 an so on. Hope thats understandable.
Any info would be much appreciated.

Cheers!
