| Mozzi version v1.1.0 sound synthesis library for Arduino |

09.Delays/AudioDelay/AudioDelay.ino

This is an example of how to use the AudioDelay class.

/* Example of modulating a signal by using a variable delay,
using Mozzi sonification library.
Demonstrates AudioDelay.
Circuit: Audio output on digital pin 9 on a Uno or similar, or
DAC/A14 on Teensy 3.1, or
