Blue Snowball Microphone
At the end of the day (or the beginning of your podcast) your microphone is the most important piece of your podcasting puzzle. I selected a Blue Snowball microphone for my show. The cost falls between a cheap Best Buy shelf mic and a pricy professional studio mic. You can find one on Amazon or Apple for around $60.
Blue Microphones also offer the Yeti and Nessie desktop microphones which I highly recommend. My next mic will most likely be one of these beautiful desktop companions.
I always wanted guests to be a strong part of The Dr. Sci-Fi Show. Having listened to several podcasts where Skype was used to perform out of studio interviews I decided to look for another solution. Skype seemed too unpredictable and often dropped the call during the interview.
I settled on using Google Hangouts as my medium of choice. This video chat room service provides a very clear audio signal and has the added benefit of allowing you to sometimes see your guest if they have a camera equipped computer. Seeing each other helps the conversation flow naturally as you can read the body cues as well as voice tone to direct your talk.
All of my show audio ends up in GarageBand, a great program which is included with every Mac. But in order to wrangle some of my audio inputs into the program I rely on two applications. Line In and Soundflower.
First off, a big thank you to the SoLoMo Show for their setup article. It was a HUGE help in getting my system configured. I recommend reading their post to further understand the workings of Line In and Soundflower.
