Audio Editing How To Voice Over

Noise Reduction Fun



I’ve been fortunate enough to acquire some mixing projects from a Southern California marketing company in the past few months or so. It’s been quite a learning experience in many ways, but I couldn’t ask for a better client to drop in my lap. Essentially, they make vignettes (marketing videos) for local companies. They film the footage, record the voice-overs and interviews, add their background music and send it to me. I then fix the audio and polish it up and mix the VO and music together for the vignettes.

The key element here is; I fix the audio. What exactly does that mean? Well, when they go to film/record the client for the vignette, sometimes background audio gets in the way. It could be a bird, a fountain or anything that’s not pleasing to the ear. When I polish that audio up and raise the volume level, all of that noise becomes very apparent and essentially ruins all of their hard work. So, before I can even mix the VO and music together, I have to get rid of that noise.

The weapon of choice for my noise removal is Adobe Audition. I basically find the frequencies that are causing trouble and tell Adobe Audition to remove those frequencies and only those frequencies in the exact spots I tell it to do so.  I wish I could say that it is a one button operation, but the truth is that a person has to use all the tools available in the software to fine-tune the process so as to not affect the voice-over itself. I’ve enjoyed the learning curve associated with noise removal. Every project is different and so one must put on the troubleshooting hat and get to work.

I thought it would be fun to show a snippet of what I have done in regards to removing the noise and mixing the overall audio on one of the projects sent me. So, let’s begin.

This first clip is the raw audio given to me. There appears to be a low-level hum in the background and you can tell he is most likely sitting in a very large room due to the amount of echo flutter.


This clip is after the noise removal has been applied. I was able to reduce the amount of echo flutter and what echo is still there has little in the way of decay. Also, the low level hum has been completely removed. I also punched up his voice with some some EQ and compression… not to mention some other little goodies the Cali Dingo has up his sleeve.


Finally, I mix that clip in with the music provided.



Thanks for checking out my latest post. I hope you found it either useful or entertaining.

Till next time…

Cartoon Sample 1


It’s been a while. The holiday season and projects galore have been keeping me away from ye old blog. However, I am now finding time to start posting some of my projects for the internet world to view. Lots of great stuff coming down the pike. Keeps me busy, but keeps me creative.

This particular sample is of a cartoon I had the pleasure making for AIMS Educational Foundation. This goes with an educational video regarding Archimedes’ Principle. This video aims to help explain what Archimedes’ Principle is in layman’s terms. So, Archimedes sets to chiseling out the technical words in favor of words that make more sense to the average student… like me. 😉

I used Adobe After Effects to create this and didn’t use any bells or whistles. I did it the old fashioned way…. I drew each frame out and synched them using pencil and paper on a light board. I know, so techie, right? I’ve found for cartooning there is nothing like the tried and true. It turns out more fluid and the artist ends up having much more control over the animation and spends less time fighting the interface of your animation program.


Cartoon Sketch Sequence
Here is a section of the walk cycle in sketch form. I put all of these (approximately 40 cells) into After Effects and tweaked in Photoshop to make it as smooth as possible.


I then scanned the drawings into Adobe Illustrator to ink and color the frames.

I also created the sound effects using Garageband and Adobe Audition. The chisel sound was the only toughie. I ended up using two variations of a clave sample and effects loop of a chisel breaking ice; blended them together in Audition and came out with a satisfactory chisel sound.

Here is the cartoon sample.




I’ll be back with some samplings in the near future.

Till then…
