Blue Microphones helped open up CES week by rolling out three new microphones. The Spark Digital is billed as the first pro-grade mic to reach iOS and is intended for those who want to add vocals or other samples in GarageBand on the iPad through a purer Dock Connector input. As a mic on the level with Blue's studio models, it has a deliberately neutral sound, gain control, zero-lag monitoring, and focus control that generates two different sound signatures.
