http://www.mobilepodcaster.com Podcasting directly into your iPad mic is great but some people may prefer better quality audio. In this episode I demonstrate podcasting with the Samson CO1U Condenser Microphone and the iPad Camera Connection Kit via Mobile Podcaster.
If you’re having trouble with your recording volume, I recommend you install Garageband for iPad ($5) and boost the microphone input level. Then when you switch to other recording apps, the mic is noticeably louder. This worked for me.
Here’s a screenshot from Garageband that shows the Input Level slider. Turn it all the way up if necessary.
