RobSmithDev | Real-Time AutoTune on Arduino - Sing like a Pro! @RobSmithDev | Uploaded November 2022 | Updated October 2024, 1 hour ago.
In this video we're going to continue from where we left off with the real-time voice repitching, and we're going to explore autotune.
The concept behind autotune is to detect what note you're trying to sing, and automatically correct the pitch of that note if you're out of tune.
We'll take a look at using the Yin algorithm to detect the pitch, optimise it so it runs fast enough on the Arduino, and then see how we can use that with our repitch code.
You can download the source code and schematics from here: robsmithdev.co.uk/youtube/autotune.zip
