If you watched some of my recent iPad 2 video recording tests, you probably noticed the loud wind related noise in those videos. That problem got me thinking about the general issue of dealing with noise in recordings made outdoors. So, last night, I took an iPad, the Apple Camera Connection Kit USB interface, and a Microsoft Lifechat LX-3000 noise cancelling headset (with microphone) outside with winds shifting from mild to moderate speeds (up to about 15 MPH) to record a short audio podcast.
The Microsoft Lifechat LX-3000 headset was plugged into the Apple Camera Connection Kit USB dongle. This dongle is normally used with a USB cable from a digital camera to transfer photo files. The dongle was plugged into the iPad’s 30-pin connector at the bottom. I used a 99 cent app named Voice Recorder for iPad (named Voice Memos for iPad in the iTunes Store) to record the podcast.
The audio levels of my voice recorded using the Lifechat headset was much lower than the levels recorded using the iPad’s built-in microphone. I adjusted the volume levels of the two segments so that you would not have to reach for the volume control twice during the short podcast. I also thought that the iPad’s microphone recording sounded much warmer than the Lifechat. However, while the iPad’s microhone did a reasonably good job of reducing noise, I think that wind caused noise was not heard at all in the segment recorded using the noise cancelling headset.
My next test will be to record video and a narration track on an iPad 2 at a noisy (wind and water) oceanside location.
