This was a microphone that Chad Johnson recommended a while ago. Its really ideal for the sort of filming that we do :)
RØDE smartLav
The smartLav is a professional-grade wearable microphone designed for use in a wide range of film, television and broadcast scenarios, or wherever professional quality audio is required in a discreet, portable format without the complication and expense of additional wireless equipment. With the smartLav the user simply mounts the microphone on the talent, connects it to a smartphone or tablet headset jack and records via the RØDE Rec app for iOS, or any other audio app of their choice.
By employing a high quality omni-directional condenser capsule the smartLav picks up sound equally from all around the microphone, allowing for versatility when mounting and ensuring a high degree of user-friendly operation.
A foam pop shield is supplied to minimise wind noise and vocal plosives (hard 'b', 't' and 'p' sounds), as well as a durable mounting clip with in-built cable management.
The smartLav is compatible with any audio app that accepts input from the headset connection, however it has been designed to pair perfectly with RØDE's RØDE Rec app for Apple iOS devices. RØDE Rec turns the user's iOS device into a fully-featured field recorder, with a wide range of equalisation presets to suit various recording situations, in addition to professional editing functions and the ability to publish to SoundCloud and Dropbox direct from the app.
