For capturing audio the DGT 650 USB Microphone by Lewitt is a good choice. As a USB microphone it can be used for recording directly to mobile devices and supports ASIO for Windows and OS X Core audio. It features a frequency range of 20 Hz to 20 kHz, and can be powered by a built-in lithium-ion battery. In addition, it is built with a headphone output, analog preamp, two condenser capsules, switchable high-pass filter, two pre-attenuation settings, and four different recording modes.
In stereo mode, the two condenser capsules provide a 90° XY stereo signal. Cardioid mode offers a polar pattern for recording speech or singing. The DGT 650 can also put out both a mono signal and a line signal. For the stereo line-in mode there's a stereo input that makes it possible to have two-channel recording from a mixer or other line source. With a dynamic range of 110 dB-A and 24-bit resolution, this microphone is suitable for many applications.
