All About Noise Floor with Alex the Audio Scientist

We’d like to introduce you to the newest member of the ACX team, Alex the Audio Scientist. Alex has a degree in Audiobook Studies from ACX University, and he’ll be stopping by the blog from time to time to explain some key ADBLCRE-ACX_Character_Iconaspects of audiobook recording and production. So without further ado, take it away Alex!

Nice to Meet You!

Enjoy the video below, and take good notes – there’ll be a quiz afterward!
