This is a demo video for the iRig Mic Cast, whic is a $40 portable micrphone for the iPhone, iPod touch and iPad.

The iRig Mic Cast is designed for recording podcasts, interviews, lectures, voice memos and speeches. It features a unidirectional pickup pattern that minimizes background noise, making it ideal for single-source audio recording.

The video demonstrates the difference between using the iPhone’s built-in microphone and the iRig Mic Cast, in a couple of noisy locations.
