Blue Microphones is unveiling some new gear at CES 2012, and it's aimed squarely at the portable recording crowd. The lineup begins with Tiki ($59), which the company bills as "the first USB mic employing advanced DSP that mimics the intelligence of human hearing," apparently through some sort of voice isolation, intelligent mute, and noise-cancelling technologies. There's no telling how all of this will actually work in practice, but it sure does seem promising. Other new devices include Mikey Digital ($99) and Spark Digital ($199). The former is a stereo external mic for iPad, iPod touch, and iPhone 4 and 4s that has a 3.5mm input with automatic and manual gain control, while the latter offers both USB and iPhone dock connections. Spark Digital is pictured above, while Tiki and Mikey Digital can be seen below.
