Lacquer cutting

Input(s):

L5: Filtered and amplified analog signal

Output(s):

L8: Physical movement of the sound

3.3) VinyGo sound mastering

For a price reduction of the project, we will use audio software instead of VinyGo sound mastering board. So this part will not be presented to the Hackaday contest.
