Audio Interface Dock for iPhone 4/4S

No, it's not a Dalek. The primary purpose of this device is to enable the audio capture quality of your iPhone 4 or 4S to become good enough for broadcast use.

Whilst the iPhone 4/4S takes pretty good HD quality video, there’s one issue that lets it down completely - its pretty dreadful sound quality. The iPhone 4's mini internal microphone only records in mono and you have no control over it. So this is where the innovative Fostex AR-4i comes in. It delivers broadcast quality stereo audio recording via its Dock connector and in-built AD/DA converter. And with its LED input level metering, gain control and headphone monitoring, the AR-4i has been designed to provide better control of your dramatically improved sound quality.

The AR-4i's enhanced audio versatility transforms an iPhone 4/4S into a serious  professional tool. For example, in ENG applications where budgets are tight, it turns an iPhone 4 into a high quality, hard working audio/video capture device for streaming audio & video to web services such as UStream. And, in radio, reporters can conduct an interview and then immediately send it from their iPhone 4 to their station for airing within minutes. No wonder national and local broadcasters are ordering the AR-4i in significant quantities.

 

• iPhone App

A dedicated, easy to use iPhone App is available for the AR-4i and this provides intuitive control of input level, microphone setting, equalisation, filters, etc.

The App can be download from Apple's iTunes App Store by clicking here
