1: Reduce echo and background noise by lowering the volume of your microphone and amplifying it later while editing. This can greatly improve the overall track and comes with an interesting side effect of making for a deeper more radio-like vocal presence. If you are using a hyper-sensitive microphone, background noises can often drown out even the most projective of speakers.
2: Find an audio editor that allows for noise cancellation and normalizing. When editing your podcast, make sure that you are using a program that has a noise cancellation filter. When using this filter, make sure to record 10-15 seconds without speaking or making any sounds so that your ambient noise may be reduced used in this filter. Normalizing can give you a consistent volume throughout your entire podcast and helps especially when you’re using a stationary microphone as you tend to move closer and further away during the recording.
3: Chose a microphone that suits your voice and needs. Not every podcaster out there really needs an expensive professional microphone. At the same time, you should avoid using a cheap mic as well. Desktop microphones that plug directly into your computer’s audio port, or built in microphones that are found on your webcam or laptop are best avoided. These microphones tend to pick up a lot of background noise and create a lot of static that can ruin an otherwise good recording. A good USB headset or USB condenser microphone can sound as good as much of the more expensive professional equipment on the market. A good example would be the Samson C01U which I and I believe Chris Pirillo uses to record with.
4: Be aware of your breathing. Professional broadcasters tend to speak with their mouths aimed slightly away from the microphone for a very good reason. This keeps their breathing out of the audio track and improves their volume levels. This can also reduce the pop sound that people make when they pronounce the letter “P”. A pop filter is also a good idea if you decide to go with a stationary microphone.
5: Add an audio track under your speech to hide breathing and unfiltered static. If you edit your podcast and apply all of the recommended filters, but still notice not only your breathing but a hint of static, a good idea would be to use a pod safe instrumental track at very low amplification under your speech. This has been shown, through several studies, to have dramatic effects on someone’s attention levels to your content. Somewhere in the human mind, if there’s music that is just out of the range of clear perception, a person will concentrate on the presentation more subconsciously in an attempt to take in and understand every part of what they are hearing. This is a method that many teachers are starting to use in classrooms by playing a very low volume radio while they give lessons.
I hope you enjoyed this top five list. I use some of these tips provided on my podcast, The Daily PWN. I wish everyone that wants to get into the world of podcasting the best.
