Beefing Up Audio

I’m just posting this because I listened to Tim Ferris interview with Tony Robbins this week and it doesn’t do well in the car or while running because of the mix. Tim has a page where you can submit comments and I wanted to post a sample to show what I’m talking about.

For anyone podcasting here are two simple things that can significantly improve your audio. Here’s a screenshot of an audio wave:

Sound Wave Before/After

You can listen to this audio file here:

If you cut the picture above in half, the left side is the “Before” and the right side is the “After”. On the left side┬áthe recording is not taking advantage of the power available to it. In other words, you are going to have to turn the volume up twice as much compared to the average song, or audio cues on your phone. These are the situations where you turn up a podcast and then when you get a text message, or your running app cuts in to tell you how many miles you are at, it blows your ears out.

Now there’s an entire profession dedicated to mastering audio – making it sound great and taking into account the devices it will be played on. I am by no means an expert in this area, but I can give you two simple things to at least get from annoying to sounding closer to an NPR podcast:

The Levelator is a free tool that will adjust the entire file so that it uses most of the dynamic range. This includes fixing where one person is louder than the other. All you do is drag and drop your file on to the window and it spits out a second file that sounds better.

Soundsoap is not free but does a great job at reducing background noise and can also add some Barry White to your sound. If you realize that the air conditioner or other stray noise in the background is annoying this can make a huge difference.

Enjoy!
