If you need to record vocals on-the-go, iRig Mic Studio, coupled with your phone, is just about the most portable solution you could ever come up with.
Into the palm-sized package, you get a 1″ electret condenser capsule, with cardioid pattern, and all of your ‘conversion’ is done right there in the microphone.
The 24-bit A/D converter works to output via the micro-USB port, and you get a variety of cables to suit, just about any device, including iPhone, iPad, Android, Mac / PC laptop and desktop computers. Should you need a 30-pin cable for your older iPad, there is one additionally available.
iRig Mic Studio comes with a stand mount, plus a handy (compact) desk stand.
There is a headphone output (with volume control knob) on board, along with gain control for the microphone.
