What Can You Do About that Pesky Background Noise?
The topic of enhancing the audio in your web video or screencast project came up in a discussion with friends during the last couple of weeks.
Of course, your best bet against degraded audio in the final production is to front load your project with decent hardware (e.g., microphone, mixer, etc.), while sanitizing your acoustic environment as much as possible from background noises.
But, then again, saying all that is sort of like telling someone that they can save a lot on the cost of multi-vitamins by simply “eating right.” The fact is, we don’t always get it right. Or, it’s not always practical; impurities seem to find their way into the system somewhere. So, that’s where a little software magic can help you.
Free Sound Editing Software is Always Good
The video at the top of this post is a short tutorial that illustrates the simplicity with which you can filter away some undesirable background sounds from the audio in your screencast or web video projects. In the demo above, you’ll find me using Audacity’s sound editor. (Free, cross-platform… both PC and Mac versions of Audacity are available for download here.)
Did I mention it’s free?
In the demo above, I kick it off with a prepared audio file devoid of any video that it may have been originally attached to. I do this a lot. All you would need to do is export the audio as its own file from your video project. Exporting it out to MP3, WAV or AIFF are some pretty common formats.
Then, simply import that sound file into a sound editor like Audacity for filtering and processing.
When you’re ready to make it part of your video again, simply save it (from the sound editor) and import it back into a sound track in your video editing software. (Maybe I should create a video tutorial to show how I do this? Let me know. I’m flexible.)
If you find the video above useful, feel free to bookmark it so you can have it as a reference in the future.
