In this article, we really hit the first big problem of the series. So far, we’ve looked at generating tones and control voltages. These are fairly straightforward problems on a microcontroller. In this issue, however, we are going to read in an audio signal, manipulate it, and then output it.
The particular module we’re going to look at this month is an enveloper – this takes an audio input and a trigger. When the trigger is activated, it lets the audio signal through. However, it’s not just an on/off. It attempts to mimic the volume profile of a real instrument, where the volume varies over time.
