Mozzi  version v1.1.0
sound synthesis library for Arduino
08.Samples/Sample/Sample.ino


This example demonstrates the Sample class.

/* Example of playing a sampled sound,
using Mozzi sonification library.
Demonstrates one-shot samples scheduled
with EventDelay.
Circuit: Audio output on digital pin 9 on a Uno or similar, or
DAC/A14 on Teensy 3.1, or
