LDC stands for Large Diaphragm Condenser microphone. And yes - It’s a mono microphone. It is surprising you can even get any signal on the second (right) channel. It’s probably because you are using ASIO4ALL. This is not really an ASIO driver, but a wrap-aroud for the standard windows drivers (and can add some weird things like “environmental effects” stuff). Make sure you do not use any effects settings in ASIO4ALL and record the signal as clean as possible.
As the microphone is a mono microphone, you have to record on a mono track. Later on you can use effects (or duplicate) to create a stereo track from that mono track if you really want to. Keep in mind that you can pan a mono track everywhere in the stereo image, so it’s not really needed to create a stereo track.
