Professional-grade voice audio from a smartphone? The iRig MIC Cast from IK Multimedia plugs into a headphone jack and takes over for the relatively low-fidelity microphone built into in most phones. It has a pickup pattern which enhances voices while reducing background noises. The result, when tested, was clear-sounding recordings and high-fidelity phone calls, including one to a radio call-in show. The unit comes with a stand and links for free iOS & Android apps.
