Podcast and Audio Editor/Writer and Voice Overs

United States - Tests: 2

I have been producing podcasts since 2006 and editing audio, particularly spoken work since the late 90's. I live for making your audio pop and shine! Need those "ums" and "ahs" removed? I'm your guy! Have two co-hosts that seem to talk on top of each other, I just might be able to smooth all that out. Need a voice over for your opening? I have you covered there too! Need a host for your podcast? I have hosted several over the years. I can even help you develop your format, create you opening and closing credits, and give you suggestions on how to improved your podcast or production. Besides my audio editing experience, I am also a web developer, so I have a great understanding of the current technology. I am also a theatre guy and have directed several theatrical productions so I can make performance suggestions and have a great sense of the entertainment pace for your production. In short, podcasting is my passion! My rate may be slightly higher than what others propose, but I am good at what I do, and quick at what I do, so you can count on the best "bang for your buck". Quality and speed, what more could you want! Contact me and we can discuss your project!
