RobSmithDev | Real-Time Voice/Music Repitch with Arduino! Sound Like A Chipmunk! @RobSmithDev | Uploaded November 2022 | Updated October 2024, 1 hour ago.
In this video we're going to explore the world of analog to digital, and digital to analog to create a real-time repitch solution with hardly any lag running totally on your Arduino UNO!
The UNO is programmed to sample, and then play back in 8-bit by building a digital to analog converter. I explain the theory of how to do the real-time repitching, and then how it's implemented in code.
I also take a quick look at some of the special tricks I've used, and deep dive into what the word volatile does and why its used in this program.
There is a followup video to this planned, to make sure you subscribe so you don't miss it!
