“You make a living by what you get. You make a life by what you give.” ~Winston Churchill


Staff Spotlight: Kevin Ziegler

 Introduction

My name is Kevin Ziegler. I am the Digital Audio Coordinator with Learning Ally. In other words, I’ m the “audio guy”. I am in charge of QA (Quality Control). Basically, I handle all the audio as it is completed. In other terms, I strive to clean up and enhance all the audio. Lastly, through this blog, I was hoping to let everyone into my world and explain a bit about what happens in “post.”

What is “Post- Production”? 

My primary focus is to level all the files across the entire book- which allows them to play smoothly without noticeable volume fluctuations. I also need to remove all the extra noise that can sometimes be introduced from different recording environments. After all of that, I “EQ” each title to best enhance the audio that is there--balancing the sonic frequencies to make it sound “good” to the ear.

What do I utilize?

I use a program called Izotope RX7, which is an industry-standard audio editing and mastering tool. This program allows me to batch process (work with many titles all at once to save time) and customizes different options for dealing with common recurring audio issues.

Is every title treated the same way?

Easiest answer is no. Most "classic audio" titles (textbooks and vocational-type books) are handled in the same fashion. As for the Voicetext, I listen to a sample from each book when it’s completed, and make a decision then about how to treat it, pulling from my different “recipes” as needed.

What are the most common issues we encounter?

Mouse clicks, background noise, plosives (popping sounds on certain letters, esp. P’s and B’s), sibilance (harsh S sounds), electrical noise, & poor recording environments.

 Setting a Proper Level:

I generally recommend that the light gray area of the Easybooks window be filled up with the level being set.

 

That being said, there isn't a precise min and max level. My suggestion is to always avoid any red in the recording level. Digital audio has a tendency to distort at those high levels. The other side if a level is so low it appears as only a blip in the window, it is more than likely much too low. I sincerely hope all this information makes sense. Also, if something looks or sounds wrong to you, point it out to the project lead.

Important takeaway: While the tools I use are indeed very powerful and beneficial, I’m sorry to say, it cannot fix everything. This is especially true when we factor in time limitations and volume of titles we produce--all with our efficient-but-small production staff. That is why it is important to have the best possible audio signal at its source. I hope these answers help deepen your understanding of our process. If you have any questions, please email me at: kziegler@learningally.org and I will get back to you. Thanks again, for all your commitment and dedication towards Learning Ally.
