Sound Academy

A Hands-on Lecture on Sound

Sound Academy is a lecture to learn sound from A to Z by experience using your voice.

Do you know what sound is, what your voice looks like, or how to use microphones or speakers? If you don't, visit Sound Academy.

It's for anyone above 10 years old who have no knowledge about sound at all, and there is nothing difficult to understand - we use videos, audios and your voice as much as possible to help you learn.


There is no upcoming workshop / lecture. Feel free to send me your request.
