I've been interested in recording using the Stereo Mid-sides technique... However, no one I know owns a Bi-directional microphone, and nor do I. I tried it with 3 mics (all caridiod, one facing forward, the other 2 in a figure 8 pattern 180 degrees - as a bi-directional mic would pick up). It works well. But it creates a clutter of cords and stands. I'd like to reduce it to 2 mics if possible (these are live recordings by the way). I don't know where to begin searching for a BD Mic... They don't seem to be in very common practice. I have a pretty small budget... I don't need anything great. Really just something to experiment with. If anyone has a suggestion of a Bi-directional microphone that is close to the above description please let me know! Thank you.
