Interesting ways to amplify sound

This project was created on 03/17/2016 and last updated 7 months ago.

Description

This is a small pre-amplifier with bass, treble, surround, compression and volume control. It is based on the teensy3.2 + audio shield. The user interface works with analog potmeters. I made a pcb which supports all the parts and wrote some software to control the whole setup. The software reads the analog pots and adjusts the parameters with software ramping to prevent 'clicks' while adjusting. More info will follow shortly ...
