The CAD M179 is an inexpensive dual large diaphragm multipattern condenser mic. Unlike the more common 3 pattern mics, it offers continuously variable patterns from omni to bidirectional. Here I'm comparing my CAD M179 to the much more expensive Schoeps CMC64. The audio in this clip was captured through an RME UFX interface and level matched using a 1 khz test tone before being exported from REAPER. Then I used Edius to switch back and forth from one microphone to the other. Of course listening on Youtube is not the best way to compare audio, so I've also provided both clips for you to download.
